Explanation:
Keeping your muscles healthy will help you to be able to walk, run, jump, lift things, play sports, and do all the other things you love to do. Exercising, getting enough rest, and eating a balanced diet will help to keep your muscles healthy for life.
Chemical reaction: NaHCO₃ + HCl → NaCl + H₂CO₃.
H₂CO₃ → H₂O + CO₂.
If amount of sodium bicarbonate (NaHCO₃) is 1 mol, then from from reaction we can calculate amount of carbon dioxide:
n(NaHCO₃) . n(CO₂) = 1 : 1.
n(CO₂) = 1 mol.
At standard pressure and temperature:
V(CO₂) = n(CO₂) · Vm
V(CO₂) = 1 mol · 22,4 L/mol.
V(CO₂) = 22,4 L.
<em>M H₂O: 1g×2 + 16g = 18g
</em>
6,02×10²³ --------- 18g
3,01×10²³ --------- Xg
X = (18×3,01×10²³)/<span>6,02×10²³
<u>X = 9g

Brass is an example of homogeneous mixture.
