Answer:

Electrolysis (of hydrochloric acid) is a way of splitting up (decomposition) of the compound (hydrogen chloride in water) using electrical energy.

Explanation:

The electrical energy comes from a d.c. (direct current) battery or power pack supply. A conducting liquid, containing ions, called the electrolyte (hydrochloric acid), must contain the compound (hydrogen chloride) that is being broken down.

How many moles are in 8.23*10^23 molecules of Bi? Explain your Answer clearly

stich3 [128]

Answer:

1.367 moles of Bi

Explanation:

a mole is 6.02 X 10^23 molecules of a substance

by dividing $\frac{8.23*10^{23} }{6.02*10^{23}}$

= 8.23/6.02 = 1.367 moles of Bi

Which of the following correctly describes a compound?

trasher [3.6K]

Answer: Option (a) is the correct statement.

Explanation:

A substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass is known as a compound.

For example, $Ca + Cl_{2} \rightarrow CaCl_{2}$

Here, $CaCl_{2}$ contains one atom of calcium and two atoms of chlorine which are chemically combined together in 1:2 ratio. Therefore, it is a compound.

Also, both chemical and physical properties of $CaCl_{2}$ will be different from Ca and $Cl_{2}$ .

Thus, we can conclude that the statement atoms are bonded together, and the compound has different physical and chemical properties than the individual element, is correct.
