Question

What is the correct chemical equation for combustion of Zn?

• A. $2Zn+O_2\to 2ZnO$
• B. $2\mathrm{Zn}+4H_{2}O\to 2\mathrm{Zn}{\left(\mathrm{OH}\right)}_2+4H_2$
• C. $\mathrm{Zn}+{\mathrm{CuSO}}_4\to {\mathrm{ZnSO}}_4+\mathrm{Cu}$
• D. $3\mathrm{Zn}+N_2\to {\mathrm{Zn}}_3{N}_2$

Answer 1

The correct option is A $2Zn+O_2\to 2ZnO$

During combustion, a substance reacts with oxygen to form its oxide producing heat and light. Metals on reaction with oxygen from metal oxides. Zinc undergoes combustion producing zinc oxide as shown below:
$2Zn+O_2\to 2ZnO$
