H atoms are found in the molecules of covalent compounds that dissolve in water. These compound are called acids (proton donors). They form acidic solutionst{acidic solutions} acidic solutions.
Because there are no ions moving about in solution with covalent molecules, they are characterised as non-electrolytes. Non-electrolyte solutions are those that do not conduct electricity.
Examples are hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid solutions (HNO3).
<h3>
What type of compounds dissociate in water to form ions?</h3>
When certain substances dissolve in water, they undergo either a physical or a chemical change that results in the formation of ions in solution. These substances are members of an important class of compounds known as electrolytes. Nonelectrolytes are substances that do not produce ions when dissolved.
A substance is known as a strong electrolyte if the physical or chemical process that generates the ions is essentially 100% efficient (all of the dissolved compound yields ions). A weak electrolyte is one in which only a small portion of the dissolved substance undergoes the ion-producing process.

Answer:
2. Muscular System
Explanation:
The muscular system is associated with body motion. Hence, the right answer is option 2.
To convert on unit to another unit, a conversion factor is needed to multiply in the value given. For the value given above, we have to convert it from miles per gallon to kilometers per liter. The factors to be used are:
1 mile = 1.61 kilometers;
1 gallon = 3.79 liters.
<span>34.0 miles / gallon ( 1.61 kilometers / 1 mile ) ( 1 gallon / 3.79 L ) = 14.44 kilometer / liter</span>
