1 answer:
Answer:
Explanation:
Hybridization in is sp3. Two bond pair and two lone pairs are present. Bond angle of molecule having sp3 hybridization is 109°5”. Because of lone pair, bond angle reduced to 104.5.
In , hybridization is sp3 and have three bond pairs and one lone pair. Because of lone pair, bond angle in NH3 is 107°.
In , hybridization is sp^2 with three bond pairs.
Bond angle of molecule having sp2 hybridization is 120°. As no lone pair is present. Therefore, bond angle will be 120°.
In and
, hybridization is sp^3 with 4 bond pairs. As no lone pair is present. Therefore, bond angle in both the molecules will be 109°5”.
Therefore, among given, BH_3 will have highest bond angle.

<u>Answer:</u> The amount of water that can be formed is 160 moles
<u>Explanation:</u>
We are given:
Moles of hydrogen gas = 170 moles
Moles of oxygen gas = 80 moles
The chemical equation for the reaction of hydrogen gas and oxygen gas follows:
By Stoichiometry of the reaction:
1 mole of oxygen gas reacts with 2 moles of hydrogen gas
So, 80 moles of oxygen gas will react with = of hydrogen gas
As, given amount of hydrogen gas is more than the required amount. So, it is considered as an excess reagent.
Thus, oxygen gas is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
1 mole of oxygen gas produces 2 moles of water
So, 80 moles of oxygen gas will produce = of water
Hence, the amount of water that can be formed is 160 moles
