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"

HELP! An atom of vanadium
Zigmanuir [339]

An atom of vanadium (V)  has 23 electrons.

Given :

A vanadium (V) atom with 23 protons and has a net charge of 0.

To find:

The number of electrons in a vanadium atom

Solution:

Number of protons in vanadium atom = 23

The 0 net charge on the atom indicates that the atom has an equal number of protons and electrons which makes it a neutral atom.

Number of electrons in vanadium atom = Number of protons in vanadium atom = 23

An atom of vanadium (V)  has 23 electrons.

The most common copper ore used in the production of copper is chalcopyrite. If a chalcopyrite ore contains 55.0% CuFeS2, how ma
sattari [20]
Answer is: 315,29 grams of copper ore.
m(<span>chalcopyrite) = ?
</span>ω(CuFeS₂) = 55,0 % = 0,55.
<span>m(Cu) = 60,0 g.
mass percentage of copper in </span>CuFeS₂:
ω(Cu) = Ar(Cu) ÷ Mr(CuFeS₂).
ω(Cu) = 63,55 ÷ 183,4.
ω(Cu) = 0,346 = 34,6 %.
mass percentage of copper in chalcopyrite:
ω(Cu) : ω₁(Cu) = 100% : ω(CuFeS₂).
ω₁(Cu) = 19,03 % = 0,1903.
m(chalcopyrite) = 60,0 g ÷ 0,1903.
m(chalcopyrite) = 315,29 g.
