How much of earth's freshwater is in the solid state or under ground?

Answer:

Insulin production would decrease.

Explanation:

Insulin and Glucagon work together to balance the sugar levels in the human blood stream. They work together in a negative feedback loop. Glucagon stimulates the liver to release glucose into the bloodstream in a process known as glycogenolysis. Insulin on the other hand is a sugar-lowering hormone.

Therefore, if glucagon secretion were permanently inhibited, insulin production would decrease as there would not be excess blood sugar to be reduced.

Answer:

Insulin production would decrease.

Answer:

Polar covalent bond

Explanation:

When the electronegativity difference between two elements A and X is 0.8, the bond AX formed will most likely be a polar covalent bond.

A polar covalent bond is one whose electronegativity difference is between 0.5 and 2.1.

In such a bond type, we have heteronuclear species with one of the species having a higher electronegativity value.

Answer:

V₂ = 1.41 L

Explanation:

Given data:

Initial temperature = 35°C (35 +273.15 K = 308.15 K)

Initial volume = 1.5 L

Final temperature = 17°C (17+273.15 K = 290.15 K)

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.5 L × 290.15 K / 308.15 k

V₂ = 435.23 L.K / 308.15 k

V₂ = 1.41 L

pOH of a solution = 5.95

Given

The concentration of hydronium ions : 8.9 x 10⁻⁹

Required

pOH

Solution

pOH = - log[OH]​

[H₃O⁺]= 8.9 x 10⁻⁹

pH = - log[H₃O⁺]

pH = 9 - log 8.9

pH = 8.05

pH + pOH = 14

pOH = 14-pH

pOH= 14-8.05

pOH = 5.95

2NaBr + I2 Right arrow. 2NaI + Br2

2AgNO3 + Ni Right arrow. Ni(NO3)2 + 2Ag

Explanation:

The activity or electrochemical series is an arrangement of elements according to their order

of reactivity.

If we look at the reactions, one thing that we must note is that the reactions that can occur are those in which an element that is higher in the series displaces another element that is lower in the series.

Br is higher in the electrochemical series than I so it can displace it. Ni is higher than Ag in the electrochemical series hence it can displace it.

Answer:

[tex]4.13[/tex] x [tex]10^{2}[/tex] = 413 kg

Explanation:

4.13 x 10 = 41.3 then we multiply 41.3 by 10 agian = 41.3 x 10 = 413

so, we multiplied ten two times that = [tex]10^{2}[/tex]

= 4.13 x [tex]10^{2}[/tex]= 413 kg

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

Note that;

1 kilogram = 1000grams

Given that;

Since, 1 kilogram = 1000grams

413 kilograms = ( 413 × 1000 )grams

413 kilograms = ( 413000 )grams

413 kilograms = 4.13 × 10⁵ g

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

Answer:

only hydrogen atoms that are part of a highly polar covalent bond are ionizable. The hydrogen atom is attracted to the lone pair of electrons in a water molecule when HCl is dissolved in water. The result is that the H−Cl bond breaks, with both bonding electrons remaining with the Cl, forming a chloride ion.

Explanation:

Answer:

In an acid molecule, hydrogen atoms may be substituted by metal atoms.

Explanation:

It is ionizable only to hydrogen atoms that are part of a strongly polar covalent bond. As HCl is dissolved in water, the hydrogen atom is drawn to the lone pair of electrons in a water molecule. The effect is that the H-Cl bond splits, with the Cl remaining with both bonding electrons, forming a chloride ion.

Mass = 3.24 g

Explanation:

Given data:

Number of atoms of cobalt = 3.31 × 10²² atoms

Mass of cobalt atoms  = ?

Solution:

We will calculate the number of moles of cobalt by using Avogadro number.

1 mole contain 6.022× 10²³ atoms

3.31 × 10²² atoms  × 1 mol / 6.022× 10²³ atoms

0.549 mol × 10⁻¹

0.0549 mol

Mass of cobalt:

Mass = number of moles × molar mass

Mass = 0.0549 mol × 58.93 g/mol

Mass = 3.24 g

Answer:

compound

Explanation:

We already know that the original substance was pure. If this substance was pure and it was powdery in nature then we have a footing to start from.

Secondly, a 4.93 g of shinny metallic liquid was left behind. This shinny metallic liquid must be an element.

Since there was a loss in mass during heating, it follows that there were other components of the pure powder.

If the reasoning stated above is correct, then the substance is a compound.

Answer: Hydrogen - 18.286%( mass present)

              Carbon - 81.714%(mass present)

Explanation:

Mass percentage does not have any unit as numerator and denominator contains the same unit. Therefore, the percent composition of C and H in C[tex]_3[/tex]H[tex]_8[/tex] is 81.8% and 18% respectively.

Mass percentage represents the the percentage of each element that is making a particular compound.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

Atomic weight of different element of calcium phosphate

C= 12g/mol , H=1g/mol

Total mass of Carbon element in C[tex]_3[/tex]H[tex]_8[/tex] = 12 × 3 = 36

Total mass of hydrogen atom in C[tex]_3[/tex]H[tex]_8[/tex] = 1 × 8 = 8

Total molar mass of  C[tex]_3[/tex]H[tex]_8[/tex] =36 + 8 =44 g/mole

Percentage of carbon in C[tex]_3[/tex]H[tex]_8[/tex] =36/44× 100  =81.8%

Percentage of hydrogen in C[tex]_3[/tex]H[tex]_8[/tex] =(8÷44)×=18%

Therefore, the percent composition of C and H in C[tex]_3[/tex]H[tex]_8[/tex] is 81.8% and 18% respectively.
