what molecule that cells mainly use to grow and build muscle is?

Answers

Answer 1

Answer:

Muscle cells use fatty acids, glucose, and amino acids as energy sources. Most cells use glucose for ATP synthesis, but there are other fuel molecules equally important for maintaining the body's equilibrium or homeostasis

Explanation:

Answer 2

Answer:

Most cells use glucose for ATP synthesis, but there are other fuel molecules equally important for maintaining the body's equilibrium or homeostasis. Indeed, although the oxidation pathways of fatty acids, amino acids, and glucose begin differently, these mechanisms ultimately converge onto a common pathway, the TCA cycle, occurring within the mitochondria (Figure 1). As mentioned earlier, the ATP yield obtained from lipid oxidation is over twice the amount obtained from carbohydrates and amino acids.

Answer:

B. The number of atoms in a molecular formula is always greater than the number of atoms in an empirical  formula.

Explanation:

It is not always true that the number of atoms in a molecular formula is always greater than the number of atoms in an empirical formula.

The chemical formulae of a compound are of two main types;

The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio. The molecular formula shows the actual ratio of the atoms in a compound.

Sometimes the number of atoms in the molecular and empirical formula can be the same.

Also, the number of atoms in the molecular formula is always greater than that of the empirical formula when they are not the same.

A gas has a density of 1.57 g/L at 40.0 °C and 2.00 atm of pressure. What is the identity of the gas?

Answers

Answer:

Neon

Explanation:

Step 1: Given and required data

Density of the gas (ρ): 1.57 g/LTemperature (T): 40.0°CPressure (P): 2.00 atmIdeal gas constant (R): 0.08206 atm.L/mol.K

Step 2: Convert T to Kelvin

We will use the following expression.

K = °C + 273.15 = 40.0 + 273.15 = 313.2 K

Step 3: Calculate the molar mass of the gas (M)

For an ideal gas, we will use the following expression.

ρ = P × M/R × T

M = ρ × R × T/P

M = 1.57 g/L × 0.08206 atm.L/mol.K × 313.2 K/2.00 atm

M = 20.17 g/mol

The gas with a molar mass of 20.17 g/mol is Neon.

In Chemistry, the gas with a molar mass of 20.18 g/mol is neon (Ne) and this is the identity of the gas.

Given the following data:

Density of gas = 1.57 g/LTemperature = 40.0°CPressure = 2.00 atm

Scientific data:

Ideal gas constant, R = 0.0821 L⋅atm/mol⋅K

Conversion:

Temperature = 40.0°C to K = [tex]273 +40=313\;K[/tex]

To determine the identity of this gas, we would apply the ideal gas law equation;

[tex]MM = \frac{R\rho T}{P}[/tex]

Where;

P is the pressure.MM is the molar mass of a gas.R is the ideal gas constant.T is the temperature.[tex]\rho[/tex] is the density of a gas.

Substituting the given parameters into the formula, we have;

[tex]MM=\frac{0.0821 \times 1.57 \times 313}{2} \\\\MM=\frac{40.35}{2}[/tex]

Molar mass = 20.18 g/mol.

In Chemistry, the gas with a molar mass of 20.18 g/mol is neon (Ne).

On average what is the time between collisions of a xenon atom at 300 K and (a) one torr pressure; (b) one bar pressure.

Answers

Answer:

(a). 132 × 10^-9 s = 132 nanoseconds.

(b)..176.5 pico-seconds.

Explanation:

(a). At one torr, the first thing to do is to find the speed and that can be done by using the formula below;

Speed = [ (8 × R × T)/ Mm × π]^1/2.

Where Mm = molar mass, T = temperature and R = gas constant.

Speed= [ ( 8 × 8.314 × 300)/ 131.293 × π × 10^-3)^1/2. = 220m/s.

The next thing to do now is to calculate for the degree of collision which can be calculated by using the formula below;

Degree of collision = √2 × π × speed × d^2 × pressure/ K × T.

Note that pressure = 1 torr = 133.32 N/m^2 and d = collision diameter.

Degree of collision = √2 × π × 220 × (4.9 × 10^-10)^2 × 133.32/ 1.38 × 10^-23 × 300.

Degree of collision = 7.55 × 10^6 s^-1.

Thus, 1/ 7.55 × 10^6. = 132 × 10^-9 s = 132 nanoseconds.

(b). At one bar;

1/10^5 × 10^3 × 56.65 = 1.765 × 10^-10 = 176.5 pico-seconds.

What does the group number plus number of bonds equal?

It’s talking about the periodic table

Answers

Answer:

A stable compound with a complete octet or electronic configuration

Explanation:

The Periodic table is the arrangements of chemical elements in horizontal rows (called 'Periods') and vertical columns (called 'Groups') based on their various physical and chemical properties.

Elements in the same group have a common quality being that they have the same number of free (valent) electrons in their outermost shell. For example, elements in group 1 all have one valent electron in the outermost shell as compared to elements in group 5 which have five valent electrons in the outermost shell. Therefore the group number tells us the number of valence electrons of all the elements in that group.

Meanwhile, elements in the same period have the same number of outermost shell but an increasing number of valence electrons as one goes across the period from left to right.

Elements form chemical bonds in an effort to achieve chemical stability. Chemical stability is achieved when the shells of the elements are fully filled with electrons and achieved a stable electronic configuration of 2 or 8.

The type of bonds formed depend on the number of valence electrons available for bonding in the outermost shell of the element.

So the element Oxygen for example which has 6 valence electrons, in its outermost shell tends to form covalent bonds (a bond achieved by sharing electrons). It is easier for oxygen to form a covalent bond by sharing its valence electrons with another element than to lose all six valence electrons in order to achieve a stable octet state  

The element Chlorine (Cl, with seven valence electrons) on the other hand tends to form electrovalent or ionic bonds by accepting an electron from a metal element like Sodium (Na) to achieve a complete octet. It is easier for Cl to achieve a stable octet state by accepting an electron than losing all 7 valence electrons.

Therefore, the group number (an indicator of the number of valence electrons in the outermost shell) plus the number of bonds formed equals a stable atom or compound with a complete electronic configuration.

in the following chemical reaction between H_2 and Cl_2 to produce HCl, what is the sum of the mass of HCl produced plus the mass of left over reactants when 0.40 g of H_2 completely reacts with 12.35 g of Cl_2?
H_2(g) + Cl_2(g) → 2HCl(g)

Answers

Answer:

Left over mass of hydrogen = 0.06 g

Mass of HCl produced = 12.41 g

Explanation:

Given data:

Mass of H₂ = 0.40 g

Mass of Cl₂ = 12.35 g

Mass of left over reactant = ?

Mass of HCl produced = ?

Solution:

Chemical equation:

H₂ + Cl₂    →     2HCl

Number of moles of H₂:

Number of moles = mass / molar mass

Number of moles = 0.40 g/ 2 g/mol

Number of moles = 0.2 mol

Number of moles of Cl₂:

Number of moles = mass / molar mass

Number of moles = 12.35 g/ 71 g/mol

Number of moles = 0.17 mol

Now we will compare the moles of HCl with H₂ and Cl₂.

                     H₂             :            HCl

                      1               :               2

                   0.2              :           2×0.2 = 0.4

                     Cl₂             :             HCl

                      1               :              2

                    0.17           :            2 × 0.17 = 0.34

Chlorine is limiting reactant.

Mass of HCl produced:

Mass = number of moles × molar mass

Mass = 0.34 mol × 36.5 g/mol

Mass = 12.41 g

Leftover mass of hydrogen:

                          Cl₂               :               H₂

                            1                :                 1

                           0.17            :             0.17

Number of moles of H₂ react with Cl₂  are 0.17.

Moles remain unreacted = 0.2 - 0.17 = 0.03 mol

Mass left over:

Mass = number of moles × molar mass

Mass = 0.03 mol × 2 g/mol

Mass = 0.06 g

The sum of the mass of HCl produced plus the mass of left over reactants is:

Mass of hydrogen = 0.06 g

Mass of HCl  = 12.41 g

Chemical Reaction

Given:

Mass of H₂ = 0.40 g

Mass of Cl₂ = 12.35 g

Mass of left over reactant = ?

Mass of HCl produced = ?

Chemical equation: H₂ + Cl₂    →     2HCl

Number of moles of H₂:

Number of moles = mass / molar mass

Number of moles = 0.40 g/ 2 g/mol

Number of moles = 0.2 mol

Number of moles of Cl₂:

Number of moles = mass / molar mass

Number of moles = 12.35 g/ 71 g/mol

Number of moles = 0.17 mol

The moles of HCl with H₂ and Cl₂.                

  H₂             :            HCl              

     1              :               2          

     0.2          :           2×0.2 = 0.4                

    Cl₂             :             HCl            

        1             :              2          

       0.17         :          2 × 0.17 = 0.34

The chlorine is limiting reactant.

Mass of HCl produced:

Mass = number of moles × molar mass

Mass = 0.34 mol × 36.5 g/mol

Mass = 12.41 g

Leftover mass of hydrogen:                

         Cl₂               :               H₂            

              1             :                 1          

               0.17       :             0.17

Number of moles of H₂ react with Cl₂  are 0.17.

c. The scientists’ calculations were incorrect; the energy totals should have been the same.

Explanation:

We must remember that energy can not be created nor destroyed according to the law of conservation of mechanical energy.

The total energy of a body remains a constant throughout its motion. For a body rolling down a ramp, the energy  changes from potential to kinetic + potential and then to kinetic.

In all of these stages of its motion, the total energy of the glass marble remains constant.

What is the angle between the carbon-hydrogen bond and one of the carbon-fluorine bonds in the fluoroform (

Answers

Answer:

110.43 degrees

Explanation:

Fluoroform is CHF3. The molecule is expected to be tetrahedral  in shape.

Recall that any molecule with four electron domains and no lone pair on the central atom (AX4) is expected to be tetrahedral with a bond angle of 109.28 degrees.

This ideal bond angle of 109.28 degrees for tetrahedral molecules only obtains when all the atoms bonded to the central atom are the same. In the case of CHF3, the bond angles of the H-C-F bond(bond angle of 110.43 degrees) is different from that of the F-C-F bonds(bond angle of 108.50 degrees) because the bonding atoms (hydrogen and fluorine) have different electronegativities and all the bonds are not equivalent.

What are the signs of ΔH, ΔS, and ΔG for the spontaneous conversion of a crystalline solid into a gas?

Answers

Answer:

ΔH>0, ΔS>0, and ΔG<0

Explanation:

Crystalline solid → Gas

ΔG < 0 T  as the reaction is Spontaneous The solid is converted into gas so the Entropy will increase as randomness is more in gas than solid, ΔS > 0

using Gibbs equation

ΔG = ΔH - TΔS

as ΔG < 0 and ΔS > 0

ΔH - TΔS <0

ΔH < TΔS ⇒ΔH >0

This gives that ΔH will be Positive but it will be less than TΔS. So we need to provide some energy to convert crystalline solid into gas.

Molecules of air in direct contact with Earth's solid, warm surface absorb heat energy with conduction.

What is conduction ?

The process by which heat is transmitted from an object's hotter end to its cooler end is known as conduction. The term "thermal conductivity" refers to an object's capacity to transfer heat, and it is represented by the letter k. Along a temperature gradient, heat flows naturally.

When two materials or objects come into direct touch with one another, conduction takes place. More quickly than in a cooler item, the molecules in a warmer one vibrate. The slower molecules clash with the faster vibrating molecules.

Ground-level heat is radiated into the lower atmosphere. In conduction, heat is transferred directly from hotter regions to cooler ones. Warmer molecules bounce vigorously and clash with molecules close by, exchanging energy.

Thus, option A is correct.
