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

Please help I will mark Brainly

Talja [164]

The reactants are the substances on the left side, which react and give the products on the right side.
The reactants are Fe and O.
The product is Fe2O3.
The arrow to the right means that the reaction is going in only one direction — the only reaction happening at the moment is that Fe and O are making Fe2O3.
(s) means the substance is in the solid state, and (g) means in a gaseous state (or the substance is a gas in that reaction).

g In Part 7, the [Cl-] in saturated NaCl is 5.4 M at room temperature. Assume that you had 1.00 ml of the saturatedsolution, and

trapecia [35]

Answer:

7.60 M

Explanation:

Our method to solve this question is to use the definition of molarity (M) concentration which is the number of moles per liter of solution, so for this problem we have

[Cl⁻] = # mol Cl⁻ / Vol

Now the number of moles of Cl⁻ will be sum of Cl in the 1.00 mL 5.4 M solution plus the moles of Cl⁻ in the 0.50 mL 12 M H . Since the volume in liters times the molarity gives us the number of moles we will have previous conversion of volume to liters for units consistency:

1mL x 1 L / 1000 mL = 0.001 L

0.5 mL x 1L/1000 mL = 0.0005 L

[Cl⁻] = 0.001 L x 5.4 mol/L + 0.0005L x 12 mol/L / ( 0.001 L + 00005 L )

= 7.6 M

This is the same as the statement given in the question.
