"Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrochloric acid

(HCl) is mixed with an aqueous solution of potassium hydroxide"
Chemistry
1 answer:
timurjin [86]3 years ago
3 0

Answer:

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

Explanation:

A neutralization reaction is the chemical reaction between an acid and an alkali to yield salt and water only.

In this particular question, the acid is hydrochloric acid while the alkali is potassium solution. We now write the equation of reaction as follows:

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

The salt formed here is KCl otherwise called potassium chloride

Boyles Law P1V1 = P2V2
arsen [322]

Answer:

A. The balloons will increase to twice their original volume.

Explanation:

Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:

P ∝ 1/V

P = k/V

PV = k (constant)

P = pressure, V = volume.

P_1V_1=P_2V_2

Let the initial pressure of the balloon be P, i.e. P_1=P, initial volume be V, i.e. V_1=V. The pressure is then halved, i.e. P_2=\frac{P}{2}

P_1V_1=P_2V_2\\\\P*V=\frac{P}{2} *V_2\\\\V_2=\frac{2*P*V}{P}\\\\V_2=2V

Therefore the balloon volume will increase to twice their original volume.

Chlorine has two isotopes, 35Cl and 37Cl; 75.77 % of chlorine is 35Cl and 24.23 % is 37Cl. The atomic mass of 35Cl is 34.969 amu
storchak [24]

Answer:

35.4528731 amu

Explanation:

To appropriately get the atomic mass unit of chlorine, we can get the answer using the masses from the isotopes. This can be obtained as follows. What we do is that we multiply the percentage compositions by the masses.

Now let’s do this.

[75.77/100 * 34.969] + [24.23/100 * 36.966]

= 26.4960113 + 8.9568618 = 35.4528731
