Question

Complete the following.
i) ZnO(s) + 2HCl(aq)
+
ii) Write the chemical reaction when NaOH was added to HCI​

Answer 1

Answer:

NaOH + HCl → H2O and NaCl

Explanation:

Complete the following.

i) ZnO(s) + 2HCl(aq) → ZnCl2 + H2O -

ii) Write the chemical reaction when NaOH was added to HCI.

NaOH + HCl → H2O and NaCl

Answer 2

Reactions are completed as follows -

I) ZnO(s) + 2HCl(aq) --> ZnCl2 + H2O

ii) NaOH + HCl --> NaCl + H2O

1. Here, products of the reaction are ZnCl2 which is zinc chloride, NaCl which is sodium chloride and H2O is chemical formula of water.
2. The first reaction is reaction between metallic oxide and acid, which results in formation of salt and water.
3. The second reaction is acid and base reaction which also yields salt and water.
