Answer 1

Answer:

mass increase!

Explanation:

<3

Answer 2

Answer:

b.distance between the objects

Explanation:

If you pull objects apart from each other they don't have as strong of a gravitational pull. think of it like a magnet the heavier the magnets the more power they can hold, the bigger they are the more surface area they have, and when you pull 2 magnets apart they slowly come weaker to each other.

Answers

2Cl + 2e⁻ → 2Cl⁻ is the half reaction correctly describes the reduction that is taking place.

What is Reduction Half Reaction ?

The half reaction of overall reaction in which reactants gain its electrons during the reaction is called Reduction Half Reaction.

What is Oxidation Half Reaction ?

The half reaction of overall reaction in which reactant loses electrons during the reaction is called Oxidation Half Reaction.

The given reaction is

2I⁻ (aq) + Cl₂ (aq) → 2Cl⁻ (aq) + I₂ (aq)

Reduction Half Reaction: 2Cl + 2e⁻ → 2Cl⁻

Oxidation Half Reaction: 2I⁻ - 2e⁻ → 2I

Here Cl₂ is an oxidizing agent and I⁻ is reducing agent.

Thus from the above conclusion we can say that 2Cl + 2e⁻ → 2Cl⁻ is the half reaction correctly describes the reduction that is taking place.

A 80.0 g sample of copper (specific heat = 0.20 J/g °C ) is heated and then added to 100 g water at 22.3 °C. The final temperature of the water and copper is 26.9°C. What is the original temperature of the copper sample, assuming that all the heat lost by the copper is gained by the water

Answers

The original temperature of the copper is 145.4 °C

What is temperature?

Temperature refers to the degree of hotness or coldness of a body. Now we know that the heat lost by the copper is equal to the heat gained by the water. The heat lost is negative while the heat gained is positive.

Hence;

-(mcdT)= mcdT

-(80.0 * 0.20 ( 26.9 - T)) = 100 * 4.12 * (26.9 - 22.3 )

-(430.4 - 16T) = 100 * 4.12 * (26.9 - 22.3 )

-430.4 + 16T = 1895.2

T =  1895.2 + 430.4 /16

T = 145.4 °C

The temperature of the copper is 145.4 °C.

What mass of carbon dioxide is produced upon the complete combustion of 17.0 LL of propane (the approximate contents of one 5-gallon tank)

Answers

The mass of carbon dioxide that is produced will be 31,671 grams or 31.671 kg

Stoichiometric calculations

First, the equation of the reaction:

[tex]C_3H_8(g)+5O_2(g)-- > 3CO_2(g)+4H_2O(g)[/tex]

The mole ratio of propane burned to carbon dioxide produced is 1:3.

The density of propane gas is 0.621 g/mL, thus, 17.0 L of propane will weigh:

        Density = mass/volume, mass = 0.621 g/mL x 17000 = 10,557 g

Mole of 10,557 g of propane = 10557/44.1 = 239.39 moles

Equivalent mole of carbon dioxide produced = 239.39 x 3 = 718.16 moles

Mass of 718.16 moles carbon dioxide = 718.16 x 44.1 = 31,671 grams or 31.671 kg

Compared to water, the pH of a buffer solution resist changes when the same small amount of a strong acid (such as HCl) or strong base (such as NaOH) is added to both.

What is buffer solution?

A buffer solution, also known as a buffer, is a mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid). When a weak acid or a weak base is applied in modest amounts, buffer solutions withstand the pH shift.

The conjugate base of the buffer system reacts with a small amount of strong acid to change it into the weak acid of the buffer system. The pH then just slightly declines, the weak acid concentration rises, and the conjugate base concentration falls.

Factors affecting the collision theory:

The influences on reaction times are numerous. The collision theory can be used to explain their effects.

0.4 M is the molarity of the solution.

The molarity of solution can be calculated by : [tex]C_M[/tex] = [tex]n/V[/tex] where,

n is the no. of moles of solute([tex]KMNO_4[/tex]) and

[tex]V[/tex] is the volume of the solution in L.

Now,

No. of moles can be calculated by: Given mass/ Molar mass

Molar mass of [tex]KMNO_4[/tex] is 158.034 g/mole

No. of moles of [tex]KMNO_4[/tex] = 36.1 g / 158.034 g/mole = 0.228 (app.) moles

Molarity of solution = 0.228 moles /0.566 L = 0.4 mol/L or 0.4 M

Hence, the molarity of a solution where 36.1 grams of potassium permanganate is dissolved in enough water to make 0.566 L of solution is 0.4 M

Using chemical equations, show how the triprotic acid h3po4 ionizes in water. Phases are optional.

Answers

The acid that contains three hydrogen ions are called triprotic acid.

The triprotic acid h3po4 ionizes in water:

White solid pure anhydrous phosphoric acid melts into a viscous liquid at 42.35 degrees Celsius. Phosphoric acid, which contains three ion hydrogen atoms, acts as a triprotic acid in an aqueous solution. The hydrogen ions disappear one at a time.

H₃PO₄ (aq)  ⇄  H⁺ (aq) + H₂PO₄⁻ (aq)          Kₐ₁ = 7.5 × 10⁻³

H₂PO₄⁻ (aq)  ⇄  H⁺ (aq) + H₂PO₄²⁻ (aq)       Kₐ₂ = 6.2 × 10⁻³

HPO₄²⁻ (aq)  ⇄  H⁺ (aq) + PO₄³⁻ (aq)            Kₐ₃ = 7.5 × 10⁻³

The first dissociation constant of phosphoric acid indicates that it is not an especially potent acid. It is a weaker acid than hydrochloric acid and sulfuric acid, but stronger than acetic acid. The ease with which each subsequent dissociation stage happens decreases. As a result, H₂PO₄⁻  is a relatively weak acid but HPO₄²⁻ is an extremely weak acid.
