Answer:

2. X₂O

Explanation:

  • Elements in group 1A are known as alkali metal. Examples include lithium, sodium, and potassium among others.
  • These elements have one valence electron in the outermost energy level and therefore form cations with a charge of +1.
  • They have a valency of 2.
  • Oxygen, on the other hand,has a valency of 2.
  • Therefore, a chemical formula of a compound formed when an element in group 1A say X reacts with oxygen will be X₂O.
  • To write the formula, we identify the symbol of the elements and their valence.
  • Then the atoms of the two elements exchange their valencies which are written as a subscript on each symbol of an element.

What is pressure in relation to a gas?
labwork [276]

The pressure of a gas is the force that a gas exerts per unit area of the container.

Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.

Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.

The volume of a container refers the size if the container.

The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.

For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.

For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.
