In two or more complete sentences explain how to balance the chemical equation, ch4 + o2 ⟶ co2 + h2o and include all steps.

 According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The reactants contain 4 atoms of hydrogen and products contain 2 atoms of hydrogen. Thus to balance hydrogen atoms, 2 is placed in front of . Now to balance oxygen atoms, 2 is placed in front of and the balanced equation is:

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
