Answer:
- % Cobalt (II) Nitrate = 30.62%
Explanation:
To calculate mass percent, first we need to <u>calculate the total mass of the mixture</u>:
- Mass Water ⇒ 0.350 kg Water = 350 g water
- Mass Ammonia⇒We use ammonia's molar mass⇒5.4 mol * 17 g/mol = 91.8 g
- Mass cobalt (II) nitrate ⇒ 195.0 g
Total Mass = Mass Water + Mass Ammonia + Mass Cobalt Nitrate
- Total Mass = 350 g+ 91.8 g+ 195 g = 636.8 g
To calculate each component's mass percent, we divide its mass by the total mass and multiply by 100:
- % Water ⇒ 350/636.8 * 100% = 54.96%
- % Ammonia ⇒ 91.8/636.8 * 100% = 0.14%
- % Cobalt (II) Nitrate ⇒ 195/636.8 * 100% = 30.62%
The charge and full ground-state electron configuration of the monatomic ion are [Ne] .

What is a monatomic ion?</h3>
- An ion with only one atom is referred to as a monatomic ion or simple ion. A polyatomic ion is one that has more than one atom, even if they are all from the same element.
- The metal (cation) in a type I binary ionic combination only produces one kind of ion. Metals that form multiple ions, or ions with various charges, are found in type II ionic compounds.
- The term "monoatomic," which combines the words "mono" and "atomic," refers to a single atom.
- A monatomic gas is a gas in which atoms are not bonded to one another. This term is typically used to describe gases.
- When compared to polyatomic gases, the thermodynamic behavior of a monatomic gas is far more straightforward.

Explanation:
Hello!
In this case, for the chemical reaction between hydrochloric acid and barium peroxide is:
Thus, since the barium peroxide (169.33 g/mol) and hydrochloric acid (36.45 g/mol) are reacting in a 1:2 mole ratio, we need to identify the limiting reactant first by computing the yielded moles of hydrogen peroxide by each reactant:
That's why the HCl is the limiting reactant, so the resulting mass of hydrogen peroxide, theoretical yield, is:
