Answer:

d. when atoms are situated in a repeating array over large atomic distances.

Explanation:

A crystalline material -

It refers to the type of solid substance where the atoms or ions are arranged in a very orderly fashion , composing a well designed lattice , is referred to as crystalline material .

These type of substances are studied under a special subtopic known as crystallography .

Hence , from the given information of the question ,

Alyssa is trying to balance the following equation: Pb(OH)2 + 2H2SO4 => PbSO4 + 2H20 What number should be used to replace th
olga nikolaevna [1]

Answer:

2 Pb(OH)2 + 2H2SO4 => 2 PbSO4 + 4 H20

Explanation:

Since there's no "?" shown in the equation, let's balance it and solve it entirely.

Pb(OH)2 + 2H2SO4 => PbSO4 + 2H20

1Pb + 10O + 6H + 2S ≠ 1Pb + 6O + 4H + 1S → it needs to be balanced.

To do this, let's start by looking at the elements that are only presnet once on each side:

On the products half, S is only present in PbSO4 → if we look at the reagents half, we can see it needs a "2" → then Pb is multiplied by 2 too → so Pb(OH)2 on the reagents half will also need a "2" → final count on O and H on the reagents side: 12O and 8H  → to balance it, you need 4 water molecules on the products side.

Electrolysis breaks down water to form hydrogen and oxygen gas. The word equation that represents this reaction is: water
Evgen [1.6K]

Answer:

When a reduction reaction and an Oxidation reaction takes place due to passing of current through water the molecules of water split into the compounds. Where it is made up of hydrogen in its state of gas and also Oxygen in its state of gas this method is most vastly is known as electrolysis.

In this process a certain direct current is passed from inside water. This direct current value can be near about 1.23 voltages the reaction that happens inside is given below.

           2 Water---> Oxygen + 4 hydrogen ions + 4 Electrons

            2 Hydrogen ions + 2 electrons ----> hydrogen gas
