Question 5
F

Which equation shows a metal being oxidised by gaining oxygen?

[1]
A

CuO+H2→Cu+H2O\mathrm{CuO + H_2 \rightarrow Cu + H_2O}CuO+H2​→Cu+H2​O

B

2Mg+O2→2MgO\mathrm{2Mg + O_2 \rightarrow 2MgO}2Mg+O2​→2MgO

C

CaCO3→CaO+CO2\mathrm{CaCO_3 \rightarrow CaO + CO_2}CaCO3​→CaO+CO2​

D

AgNO3+NaCl→AgCl+NaNO3\mathrm{AgNO_3 + NaCl \rightarrow AgCl + NaNO_3}AgNO3​+NaCl→AgCl+NaNO3​
