Answer: Option (b) is the correct answer.

Explanation:

A compound when dissolved in a liquid or solution dissociates into ions then it is known as an electrolyte.

An ionic compound will always be an electrolyte.

For example, sodium hydroxide being an ionic compound will readily dissociate into ions when dissolved in water.

Hence, sodium hydroxide is able to conduct electricity. Therefore, it is an electrolyte.

amid [387]

Answer:

MnSO₄.7H₂O

Explanation:

To solve this question, we need to convert the mass of the dehydrated MnSO₄. The difference between mass of the hydrate and dehydrated compound is the mass of water. With the mass we can find the moles of water and the formula of the hydrate:

<em>Moles MnSO₄ -Molar mass: 151g/mol-:</em>

17.51g * (1mol / 151g) = 0.116 moles

<em>Moles H₂O -Molar mass: 18g/mol-:</em>

32.14g-17.51g = 14.63g * (1mol / 18g) = 0.813 moles

The ratio of moles MnSO₄: Moles H₂O represent the amount of water molecules in the hydrate:

0.813mol / 0.116mol = 7 molecules of water.

The hydrate formula is:

<h3>MnSO₄.7H₂O</h3>

If the thorium-232 isotope emits an alpha particle, what would be the atomic number of the resulting atom?
inysia [295]

<span>Answer is: atomic number of resulting atom is 88.
Alpha particle is nucleus of a helium-4 atom, which is made of two protons and two neutrons.
Nuclear reaction: ²³</span>²Th → ²²⁸Ra + α (alpha particle).

Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.

Why is water a polar compound?
anastassius [24]

Answer:

Water is a unique molecule and thus consists of unique properties. It is considered polar because of its charges and its bent shape. The two oxygen are negative and the hydrogen is positive. This creates two poles, making the molecule polar. This is an example of polar covalent chemical bonding.
