2B + 3H2 2BH3 How many moles of BH3 are synthesized when 27.0 moles of H2 completely react?

Chemistry
1 answer:
STatiana [176]2 years ago
3 0

Answer: 18.0 moles of BH_3 will be produced when 27.0 moles of H_2 completely react.

Explanation:

The balanced chemical equation is:

2B+3H_2\rightarrow 2BH_3  

According to stoichiometry :

3 moles of H_2 produce = 2 moles of BH_3

Thus 27.0 moles of H_2 will produce=\frac{2}{3}\times 27.0=18.0 moles  of BH_3

Thus 18.0 moles of BH_3 will be produced when 27.0 moles of H_2 completely react.

Choose the correct total number of electron domains (bonding and nonbonding) about a central atom if the angle(s) between the el
slamgirl [31]

Answer:

The central atom has 3 electron domains.

Explanation:

According to the Valence Shell electron pair repulsion theory (VSEPR) put forward by Gillespie and Nyholm in 1957, the shape of a molecule is determined by repulsion between all the electron pairs (electron domains) present in the valence shell.

The electron pairs or electron domains are known to position themselves as far apart in space as possible in order to minimize repulsions.

Hence, when the central atom of a molecule contains three electron domains, they are positioned at an angle of 120° from each other to minimize repulsions. Hence the answer.
