These are the formulas of each compound mentioned:
1) Hydrogen chloride: HCl
2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.
3) Sodium chloride: NaCl
4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.
5) Water: H2O. The number 2 to the right of H is a subscript.
The the chemical equation is:
HCl + NaHCO3 → NaCl + CO2 + H2O
Check the balance
element left side right side
H 1+1 = 2 2
Cl 1 1
Na 1 1
C 1 1
O 3 2+1 = 3
Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.

Answer:
The answer is
<h2>59.6 g </h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
Density of aluminum = 2.00 g/mL
volume = 29.8 mL
The mass is
mass = 2 × 29.8
We have the final answer as
<h3>59.6 g</h3>
