Answer:
0.154g of H2
Explanation:
First, we'll begin by writing a balanced equation for the reaction between zinc (Zn) and hydrochloric acid (HCl). This is illustrated below:
Zn +2HCl —> ZnCl2 + H2
Next, let us determine the mass of Zn that reacted and the mass of H2 formed from the balanced equation.
This is illustrated below:
Molar Mass of Zn = 65g/mol
Molar Mass of H2 = 2x1 =2g/mol
From the balanced equation above,
65g of Zn produced 2g and H2.
Therefore, 5g of Zn will produce = (5 x 2) /65 = 0.154g of H2
From the calculations made above, 5g of Zn produced 0.154g of H2
