Question

The reaction that gives $C{O}_2$ as one of the products is:

• A. $3C+4HN{O}_3\underset{}{\overset{\Delta }{\to }}$
• B. $6NaOH+2C\to$
• C. $Sn{O}_2+2C\to$
• D. $F{e}_2{O}_3+3C\underset{}{\overset{{250}^o-{400}^{o}C}{\to }}$

Answer 1

The correct option is A $3C+4HN{O}_3\underset{}{\overset{\Delta }{\to }}$

$3C+4HN{O}_3\to 3C{O}_2+4N{O}_2+2H_{2}O$

$6NaOH+2C\to 3H_2+2Na+2N{a}_{2}C{O}_3$

$Sn{O}_2+2C\to Sn+2CO$

$F{e}_2{O}_3+3C\to 2Fe+3CO$

Hence, option $A$ is correct.
