Question

What information do you get from the following
chemical equation ?
Zn(s) + 2HCl (dil) → ZnCl, (aq) + H, (g)
​

Answer 1

Answer:

Zinc is in solid state. HCl is in liquid and dilute form. ZnCl is in liquid form and H2 is in gaseous form. Also, if you put upward arrow after H2, it shows that this gas is released during the reaction.

Hope it helps.!❤

Answer 2

Answer:

The information which the given equation provide us is:

1. Zinc reacts with hydrochloric acid to give zinc chloride and hydrogen.

2. One atom of zinc reacts with two molecules of HCl to give one molecule of zinc chloride and one molecule of hydrogen.

3. One mole of zinc reacts with two moles of HCl to give one mole of zinc chloride and one mole of hydrogen.

4. 65 parts by weight of zinc reacts with 71 parts by weight of hydrochloric acid to give 136 (65 + 71) parts by weight of zinc chloride and 2 parts by weight of hydrogen.

5. One mole of zinc reacts with 2 moles of HCl to give one mole of zinc chloride and 22.4 litres of hydrogen at S.T.P.

Hope this helps....
