If the oxidation number of an atom decreases, the atom has undergone oxidation.
Bumek [7]

Oxidation is a process when an atom, a group of atoms, or an ion loses electrons.

For example,

Cu⁰ -------> Cu⁺² + 2e⁻. This is an oxidation process.

As we can see an oxidation number was 0, and it became +2. The oxidation number is increased. Oxidation number of the atom, when an atom has undergone oxidation, increases.

So, answer is b.False.

What mass of ch4 is consumed when 587. 9 kj of energy is evolved from the combustion of a mixture of ch4(g) and o2(g)? show the
katen-ka-za [31]

Mass of CH₄ is 10.591 g.

The molar mass is a crucial characteristic of the material that is independent of sample size. The coherent unit of molar mass in the International System of Units (SI) is kg/mol. However, molar masses are usually generally given in g/mol due to historical considerations.

A chemical compound's molar mass is calculated by dividing its mass by the number of moles of the substance that make up the sample.

Δg = 587.9 KJ

CH₄ Molar mass = 16.05 g/mol

mol CH₄ = Δg / ΔH°

              = 587.9 / 890.3 KJ/ mol

              = 0.6603 mol CH₄

Mass CH₄ = 0.6603 × 16.05 g/mol

                = 10.591 g

Therefore, the mass of  CH₄ is 10.591 g.
