Choose the balanced chemical equation below that best represents the following reaction:

Chemistry
1 answer:
suter [353]2 years ago
8 0

The balanced chemical equation :

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

<h3>Further explanation</h3>

A balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same

When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .

This statement shows that

Reactants (located to the left of the reaction)

Baking soda (NaHCO₃) and Hydrochloric acid (HCl)

product (located to the right of the reaction)

Carbon dioxide(CO₂),water  (H₂O) and Sodium chloride (NaCl).

So the reaction :

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

The partial pressure of O2 in air at sea level is 0.21atm. The solubility of O2 in water at 20∘C, with 1 atm O2 pressure is 1.38
adell [148]

Answer:

1.21x10^{-3} M

Explanation:

Henry's law relational the partial pressure and the concentration of a gas, which is its solubility. So, at the sea level, the total pressure of the air is 1 atm, and the partial pressure of O2 is 0.21 atm. So 21% of the air is O2.

Partial pressure = Henry's constant x molar concentration

0.21 = Hx1.38x10^{-3}

H = \frac{0.21}{1.38x10^{-3} }

H = 152.17 atm/M

For a pressure of 665 torr, knowing that 1 atm = 760 torr, so 665 tor = 0.875 atm, the ar concentration is the same, so 21% is O2, and the partial pressure of O2 must be:

P = 0.21*0.875 = 0.1837 atm

Then, the molar concentration [O2], will be:

P = Hx[O2]

0.1837 = 152.17x[O2]

[O2] = 0.1837/15.17

[O2] = 1.21x10^{-3} M
