Explanation:
Mol of HBr = mass/Mr = 117/(1+80) = 1.444
From equation, 2 moles hydrogen bromide reacts with 1 mole of barium hydroxide.... So 1.444 moles of hydrogen bromide react with (1.444/2) = 0.722 moles of barium hydroxide.
To balance Ca + Cl2 = CaCl2 you'll need to be sure to count all of atoms on each side of the chemical equation.
Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Calcium + Chlorine gas.
