Question 51
Easy

When lithium carbonate is heated, it thermally decomposes according to the equation:

Li2CO3(s)→Li2O(s)+CO2(g) \text{Li}_2\text{CO}_3(\text{s}) \rightarrow \text{Li}_2\text{O}(\text{s}) + \text{CO}_2(\text{g}) Li2​CO3​(s)→Li2​O(s)+CO2​(g)

When 11.435 g of lithium carbonate is heated, the mass of solid remaining is 4.618 g.

Calculate the mass of carbon dioxide that has been released.

Give your answer to three significant figures.
