I don’t understand the equations

inna [77]

So the equation is balanced, meaning they have the smallest amounts of each element in the reactants to create the products.

So, 2 moles of H2S (the coefficient) contributes to 2 moles Ag2S, which is why the ratio is 2:2.

I hope that made sense.

Answer:

The answer is "Option B"

Explanation:

Formula:

Na atoms= Na atoms moles \times NA

$= \frac{mass}{Na \ Molar\ mass} \times 6.022 \times 10^{23}\\\\= \frac{9.2}{23} \times 6.022 \times 10^{23}\\\\=0.2875 \times 6.022 \times 10^{23}\\\\=2.4 \times 10^{23}\ atoms \\\\$
