<h3><u>Answer;</u></h3>

Chemical bond

<h3><u>Explanation;</u></h3>
  • <em><u>Chemical bond is an attraction that is formed between atoms or molecules which enables formation of chemical compounds. </u></em>
  • <em><u>Chemical bonds result from attraction of atoms to each other through the sharing of electrons, exchanging of electrons or the transfer of electrons or electrostatic forces.</u></em>
  • Chemical bonds may be classified as metallic bond, ionic bond or covalent bond.
  • Ionic bonds occur when electrons are transferred from one atom to another, and the result is attraction between the resulting oppositely charged ions. Covalent bonds occurs as a result of sharing of electrons between non-metal atoms. Metallic bond occur in metals as a result of positively charged nucleus and a sea of electrons in the atoms.

Explanation:

When an atom bonds with another atom then it results in the formation of a chemical bond.

This formation of bond could be due to transfer or sharing of electrons.

When a chemical bond is formed due to transfer of electrons then this type of bond is known as ionic bond.

When a chemical bond is formed due to sharing of electrons then this type of bond is known as covalent bond.

If a gas is 0.8L at 900 mm Hg and 400K, what is the new pressure if the volume decreases to 0.5L and 300K?
mezya [45]

Answer:

The new pressure of the gas is 1080 mmHg

Explanation:

The general equation provides a way to calculate the relationship between changesnp in volume, temperature and pressure of a given mass of gas.

The general gas equation is given as P1V1/T1 = P2V2/T2

Where P1 is initial pressure of gas

V1 is initial volume of gas

T1 is initial temperature of gas

P2 is final pressure of gas

V2 is final volume of gas

T2 is final temperature of gas

From the given question, P1 = 900 mmHg, V1 = 0.8 L, T1 = 400 K, P2 = ?, V2 = 0.5 L, T2 = 300 K

Making P2 subject of the general gas equations:

P2 = P1V1T2/V2T1

P2 = (900 × 0.8 × 300) / (0.5 × 400)

P2 = 1080 mmHg

Therefore, the new pressure of the gas is 1080 mmHg.

Write a word equation for a reaction in which hydrogen acts as a reducing agent
lubasha [3.4K]

Hydrogen reduces the oxides of the less active metals, viz. removes oxygen from strongly heated metal oxides when passed over them, and in the process gets oxidized itself to water.

Both alkali metals and Hydrogen acts as a reducing agent which is proved by the following reactions:-

CuO + H2 Cu + H2O

CuO + 2Na Cu + Na2O

In both cases CuO is oxidised.
