Question

What happens when - give balanced chemical equation:

(i) BCl3

reacts with LiAlH4

(ii) Ca2

B6O11 reacts with Na2

CO3

Answer 1

co3 happen s when given balanced chemical equation

Answer 2

Answer : The chemical reactions are given below.

Explanation:

(i) The balanced chemical reaction will be,

$4BCl_3+3LiAlH_4\rightarrow 2B_2H_6+3LiCl+3AlCl_3$

By the stoichiometry of the reaction:

4 moles of boron chloride react with 3 moles of lithium aluminium hydride to give 2 moles of borane, 3 moles of lithium chloride and 3 moles of aluminium chloride.

(ii) The balanced chemical reaction will be,

$Ca_2B_6O_{11}+2Na_2CO3\rightarrow 2CaCO_3+Na_2B_4O_7+2NaBO_2$
