1)identify the reactants and the products

2) Is the equation balanced?show how you know
3) What is the evolume of the missing (g) for the product? shouw your work

Answer 1

1) Identify reactants and products
- Reactants: NaHCO3 (baking soda) and HC2H3O2 (acetic acid, vinegar)
- Products: NaC2H3O2 (sodium acetate), H2O (water), CO2 (carbon dioxide)

2) Is the equation balanced? Show how you know
Equation: NaHCO3 + HC2H3O2 -> NaC2H3O2 + H2O + CO2

Count atoms on each side (per 1:1:1:1:1 stoichiometry)
- Na: left 1, right 1
- C: left 1 (from NaHCO3) + 2 (from HC2H3O2) = 3; right 2 (in NaC2H3O2) + 1 (in CO2) = 3
- H: left 1 + 4 = 5; right 3 (in NaC2H3O2) + 2 (in H2O) = 5
- O: left 3 + 2 = 5; right 2 + 1 + 2 = 5

All elements balance, so the equation is balanced.

3) Mass of the missing product (given masses)
Given: reactants 12 g (NaHCO3) and 25 g (acetic acid) → total reactant mass = 12 + 25 = 37 g.
Given product masses: NaC2H3O2 = 10 g, H2O = 20 g, CO2 = ? g.

By conservation of mass: total products mass = total reactants mass
10 + 20 + (CO2 mass) = 37
CO2 mass = 37 − 30 = 7 g

Answer: the missing product (CO2) has mass 7 g.
