Question

There is loss in weight when mixture of $L{{i}_{2}}C{{O}_{3}}$ and $N{{a}_{2}}C{{O}_{3}}.10{{H}_{2}}O$ is heated strongly. This loss is due to

• A. $L{{i}_{2}}C{{O}_{3}}$
• B. $N{{a}_{2}}C{{O}_{3}}.10{{H}_{2}}O$
• C. Both [a] and [b]
• D. None of these

Answer 1

Answer: (C)

Both [a] and [b]

Answer 2

$L{{i}_{2}}C{{O}_{3}}\xrightarrow[{}]{{}}L{{i}_{2}}O+C{{O}_{2}}\uparrow$ $N{{a}_{2}}C{{O}_{3}}.10{{H}_{2}}O\xrightarrow[{}]{{}}N{{a}_{2}}C{{O}_{3}}+10{{H}_{2}}O\uparrow$
