Which law represents a balanced chemical equation? A. Avogadro’s hypothesis B. ideal gas law C. law of conservation of mass D. Newton’s first law of motion E. Newton’s second law of motion

Which law is reflected in the process of balancing an equation for a chemical reaction?

When the coefficients of the formulas in a chemical equation have been adjusted to satisfy the law of of , the equation is said to be balanced.

Consider the following statements, choose the incorrect one(s):1 point[A]. The chemical equation is balance to satisfy the law of conservation of mass in chemical reaction.[B]. We should never change the formula of an element or compound to balance and equation.[C]. Those reaction in which heat is evolved are known as exothermic reactions.[D]. When Methane (CH4) burns in oxygen of air it forms carbon monoxide and water vapour.

Why chemical equations must be balanced?

(a) State the law that is followed by balancing a chemical equation.(b) Balance the following chemical equation: Na + H3O → NaOH + H2
