Question

Which of the following reaction is /are correct ?
$Mg\left(s\right)+C{l}_2\left(g\right)\to MgC{l}_2\left(s\right)$ .....(1)
$Mg\left(s\right)+2HCl(aq.)\to MgC{l}_2\left(s\right)+H_2\left(g\right)$.....(2)

• A. only (1)
• B. only (2)
• C. both (1) and (2)
• D. none of them

Answer 1

Answer: (C)

both (1) and (2)
