Answer:

0.0977M is the concentration of the final solution

Explanation:

In a dilution process, to the original solution (Stock solution) you add more solvent in order to decrease its original concentration. To know how many times the solution was diluted you must find the dilution factor (Ratio between the initial and final volume). That is:

Intial Volume: 5.73mL

Final volume: 5.73mL + 20.26mL = 25.99mL

Dilution factor: 25.99mL / 5.73mL = 4.536 → 4.536 times the solution is diluted. The concentration of the diluted solution is:

0.443M / 4.536 =

The concentration of the solution is 0.099 M.

We have to use the dilution formula here;

C1V1 = C2V2

Where;

C1 = initial concentration

C2 = final concentration

V1 = initial volume

V2 = final volume

Now;

C2 = C1V1/V2

C2 =0.443 M × 5.73 mL / (5.73 mL  + 20.26 mL)

C2 = 0.099 M

Explanation:

Let us represent lauric acid with the symbol LaCOOH and the anion as LaCOO-. The reaction between the anion and H2SO4 is;

LaCOO-(aq) +  H2SO4(aq) ----->  LaCOOH(aq) + HSO4-(aq)

Number of moles of LaCOO- = 2.75 g/200 g/mol = 0.014 moles

Since the mole ratio of the reaction is 1:1, then the amount of H2SO4 required is also 0.014 moles

Then;

n = CV

n = number of moles

C= concentration

V = volume

V = n/C

V = 0.014 moles/4.0 M

V= 3.5 * 10^-3 L

V = 3.5 mL

Answer: Periodic Trends

Zeff increases because the positive charge of the nucleus increases while the outermost electrons stay the same distance from the nucleus (filling the same orbital). In other words, going across a period, the outermost electrons are more tightly held. This explains the trend in atomic radius.

It refers to how strongly an atom attracts electrons from other atoms. Electronegativity is a measure of an atom's ability to draw electrons towards itself, or the ability of the nucleus to hold electrons tightly

Answer:

4 g/cm³

Explanation:

Volume(V) = 60 cm³

mass (m) = 240 gm

density (d) = ?

We know density is defined as mass per unit volume so

d = m / v

= 240 / 60

= 4 g/cm³

Answer:

methane on the other hand is made of one carbon atom and 4 hydrogen atoms. like water, the bonds are covalent.

Liquid methane and Liquid water are both covalent compounds, thus, they both have covalent bonds in common.

Methane is a covalent compound which exists as a gas at room temperature.

Methane is composed of four hydrogen atoms and a carbon atom linked together by covalent bonds.

Water is a covalent compound which exists as a liquid at room temperature.

Water is composed of two atoms of hydrogen and one atom of oxygen linked together by covalent bonds.

Since both liquid water and liquid methane are covalent compounds, they both have covalent bonds in common.

Therefore, liquid methane and liquid water have covalent bonds in common.

Hello!

In this case, since the molarity of a solution is computed via:

[tex]M=\frac{n}{V}[/tex]

Whereas we are asked to compute the volume:

[tex]V=\frac{n}{M}[/tex]

Thus, we first compute the moles in 12.0 g of NaOH as its molar mass is about 40.0 g/mol:

[tex]n=\frac{12.0g}{40.0g/mol}=0.3mol[/tex]

Thus, at first instance, the volume liters is:

[tex]V=\frac{0.3mol}{2.0mol/L} \\\\V=0.15L[/tex]

Which in milliliters is:

[tex]V=0.15L*\frac{1000mL}{1L}\\\\V=150mL[/tex]

Answer:

[NaCl] = 0.31 m

Explanation:

Molality is a sort of solute's concentration, that indicates the moles of solute contained in 1kg of solvent.

In this problem:

solute → NaCl

solvent → H₂O

We need the mass of solvent in kg and we have the volume, so let's convert the volume to mass by the use of density.

1 g/mL = mass / 159 mL

(Notice we needed to convert the volume from L to mL)

159 g is the mass of water. We convert to kg

159 g . 1 kg/1000 g = 0.159 kg

We convert the mass of solute to moles → 2.89 g . 1mol/ 58.45 g = 0.049 moles of NaCl

Molality → mol/kg → 0.049 mol /0.159 kg = 0.31 m

Answer: The average kinetic energy of the particles in a gas is proportional to the temperature of the gas. Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer. The volume of the gas therefore becomes larger as the temperature of the gas increases.

Answer:

Human chorionic gonadotropin (HCG) injections are much safer to use with some mild side effects to treat issues of testicular atrophy. Human chorionic gonadotropin (HCG) injections would increase blood flow and enable the testes' produce testosterone, reduce the shrinkage of the testicles and it also aids in the production of sperm cells which has been initially impaired due to testicular atrophy.

Explanation:

Anabolic steroid is a drug that plays the role of testosterone.

Testicular atrophy is the shrinkage of the testicles caused by old age or infections. Once it occurs, it lowers the production of testosterone and sperm cells.

Trenbolone increases muscle building, aids lean fat deposition, reduces the production of testosterone, and could also lead to testicular atrophy.

There are six main requirements for a typhoon to form and develop. It needs an abundance of unstable atmosphere/ vertical motion. The ocean waters must have a temperature of 26.5ºC spanning from the surface up to a depth of at least 50 meters (160 ft.) or more. Another requirement is to have too much water vapor present in air known as relative humidity. The low vertical wind shear also contributes to the formation of typhoon. It also needs an existing distance/pre-existing disturbance  for typhoon development which is 500 km (300 mi) from the equator. The Coriolis force causes the powerful wind to spin at this particular region.

If any one of these requirements were below average or minimum, a tropical cyclone would not form.

Answer:

CH₂

Explanation:

From the question given above, the following data were obtained:

Mass of Carbon (C) = 5.41 g

Mass of compound = 6.32 g

Empirical formula =?

Next, we shall determine the mass of Hydrogen (H) in the compound. This can be obtained as follow:

Mass of Carbon (C) = 5.41 g

Mass of compound = 6.32 g

Mass of Hydrogen (H) =?

Mass of H = mass of compound – mass of C

Mass of H = 6.32 – 5.41

Mass of H = 0.91 g

Finally, we shall determine the empirical formula of the compound. This can be obtained as follow:

Mass of C = 5.41 g

Mass of H = 0.91 g

Divide by their molar mass

C = 5.41 / 12 = 0.451

H = 0.91 / 1 = 0.91

Divide by the smallest

C = 0.451 / 0.451 = 1

H = 0.91 / 0.451 = 2

Thus, the empirical formula for the compound is CH₂

In this case, since the mole ratio between nitrogen and oxygen is 2:5 respectively, we realize we first need the moles of nitrogen given it's atomic mass (14.01 g/mol):

[tex]n_N=0.750g*\frac{1mol}{14.01g}=0.0535molN[/tex]

Now, we calculate the moles of oxygen:
