<u>Answer:</u> When an atom is an ion, it must have a charge.

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.  <u>For Example:</u> Sodium looses 1 electron to form Na^+ ion.
  • When an atom gains electrons, it results in the formation of negative ion known as anion. <u>For Example:</u> Chlorine gains 1 electron to form Cl^- ion.

Hence, when an atom is an ion, it must have a charge.

Which of the following will have the slowest rate of diffusion at a given temperature?
marysya [2.9K]
<h3>Answer:</h3>

Chlorine gas (Cl₂)

<h3>Explanation:</h3>
  • According to the Graham's law of diffusion, the diffusion rate of a gas is inversely proportional to the square root of its density or molar mass.
  • Therefore, a lighter gas will diffuse faster at a given temperature compared to a heavy gas.
  • Consequently, the heavier a gas is then the denser it is and the slower it diffuses at a given temperature and vice versa.

In this case we are given gases, CI₂

, H₂,He and Ne.

  • We are required to identify the gas that will diffuse at the slowest rate.
  • In other words we are required to determine the heaviest gas.

Looking at the molar mass of the gases given;

Cl₂- 70.91 g/mol

H₂- 2.02 g/mol

He - 4.00 g/mol

Ne- 20.18 g/mol

Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among the choices given.

Determine the formula of chromic acid.
Katyanochek1 [597]

<u>Answer:</u> The formula of chromic acid is H_2CrO_4

<u>Explanation:</u>

We are given an ionic compound named as chromic acid. This acid is formed by the combination of hydrogen ion and chromate ion.

An acid is defined as the substance which releases hydrogen ion when dissolved in water.

Hydrogen is the 1st element of periodic table having electronic configuration of 1s^1.

This element will loose 1 electron to form H^{+} ion.

Chromate ion is a polyatomic ion having chemical formula of CrO_4^{2-}

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is H_2CrO_4

Thus, the formula of chromic acid is H_2CrO_4

What do atom, molecules, and elements have in common
____ [38]

Answer:

Solids, liquids, gases - all matter - are made up of atoms (or other things, like molecules, that are made from atoms)! ELEMENTS are the kinds of atoms that we can have. Carbon is an element, hydrogen is an element, and so is oxygen. ... Atoms can join together - they form bonds together - to make MOLECULES.
