The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req
UNO [17]

This problem is providing the chemical reaction whereby barium nitride reacts with water to produce barium hydroxide and ammonia, so the number of moles of barium nitride are required in order to produce 8.3 moles of ammonia. It asks for us to evaluate the student's setup, so we conclude the answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3", according to:

<h3>Mole ratios:</h3>

In chemistry, stoichiometric calculations are used to figure out the moles or mass of a substance, given information about another one in the reaction. In this case, for the given chemical equation:

Ba_3N_2 + 6H_2O \rightarrow 3Ba(OH)_2 + 2NH_3

We evidence a 1:2 mole ratio of barium nitride to ammonia, for that reason, the student's setup:

8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{1 mol NH_3}

Is incorrect, because the ammonia must be accompanied by a 2 rather than the 1 it is given there:

8.3 mol NH_3 * \frac{1 mol Ba_3N_2 }{2mol NH_3}

Thereby, the correct answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3"

The number of B2H6 molecules
zlopas [31]

Answer:

6.022 × 10²³ molecules of B₂H₆

Explanation:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

B₂H₆ molecules:

21.63 g = one mole of B₂H₆= 6.022 × 10²³ molecules of B₂H₆
