Complete the folllowing blands in the equation as indicated.
$C a H_{2} (s) + 2 H_{2} O (a q) \to C a (O H)_{2} (s) + 2 H_{2} (g)$
(a) moles : $1 m o l e + \dots \to \dots + \dots$
(b) Grams: $42 g + \dots \to \dots + \dots$
(c) Molecules : $6.02 \times 10^{23} + \dots \to \dots + \dots$

Solution

$C a H_{2} (s) + 2 H_{2} O (a q) \to C a (O H)_{2} (s) + 2 H_{2} (g)$

(a) moles : $1 m o l e + 2 m o l e \to 1 m o l e + 2 m o l e$

(b) Grams: $42 g + 36 g \to 74 g + 4 g$

(c) Molecules : $6.02 \times 10^{23} + 2 \times 6.02 \times 10^{23} \to 6.02 \times 10^{23} + 2 \times 6.02 \times 10^{23}$
