the following chemical equation shows the reaction of methane and oxygen to form carbon dioxide and water.

ch4 + 2o2 ⇒ co2 + h2o

balance the above reaction by writing the correct coefficient(s). you may do this by writing what coefficients should be added.
describe how a balanced equation demonstrates the law of conservation of mass.

Explanation:

Balancing the Hydrogen atoms on the right side,

Balancing the Oxygen atoms on the left side,

In a balanced equation, the product side and the reactant side must have the same mass of matter, since matter cannot be destroyed or created according to the law.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
