how many moles of ammonium sulfate can be made from the reaction of 30.0 mol nh3 with h2so4 according to the following equation.

Answers

15.0 moles of ammonium sulfate are formed by the reaction of 30.0 moles of ammonia with sulfuric acid.

Let's consider the reaction between ammonia and sulfuric acid to produce ammonium sulfate.

2 NH₃ + H₂SO₄ ⇒ (NH₄)₂SO₄

The molar ratio of NH₃ to (NH₄)₂SO₄ is 2:1. The moles of (NH₄)₂SO₄ produced from 30.0 moles of NH₃ are:

$30.0 mol NH_3 * (1mol(NH_4)_2SO_4)/(2molNH_3) = 15.0 mol(NH_4)_2SO_4$

15.0 moles of ammonium sulfate are formed by the reaction of 30.0 moles of ammonia with sulfuric acid.

Water has a higher boiling point than expected because A. there is so much water vapor in the atmosphere. B. water molecules are not very massive. C. hydrogen and oxygen form single covalent bonds. D. of the strong attractions between polar water molecules

Answers

The correct answer is C. Water has a higher boiling point than expected because hydrogen and oxygen form single covalent bonds. Molecules of water is bound together by strong attractions which needs high energy to break resulting to a higher boiling point of water than most substances.

Final answer:

Water has a higher boiling point than expected because D. of the strong attraction between polar water molecules.

Explanation:

The higher boiling point of water is due to the strong attraction between polar water molecules. Water molecules are polar because of the unequal distribution of electron density between the oxygen and hydrogen atoms, resulting in a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen atom.

Thus, these partial charges create attractive forces called hydrogen bonds between neighboring water molecules, making it difficult to separate the molecules and requiring more heat energy to overcome these attractive forces and reach the boiling point.
