C4H10 is a saturated hydrocarbon or alkane with the general formula CnH(2n+2). Since n = 4 for C4H10, the prefix is but-, and this compound is butane. The rest of the substances are common compounds: oxygen, carbon dioxide and water, so the word equation is:
butane combusted with oxygen gives carbon dioxide and water vapor
Atoms are like the letters of the alphabet the compounds they make are like words.

Answer: Law of conservation of mass explains these observations.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.

Mass of reactants= mass of Mg+ mass of
= 48 g + 32 g = 80 g
Mass of products = mass of
= 80 g
Thus mass of reactants is equal to mass of products, thus law of conservation of mass is obeyed.
