Which of the following equations best represents the meaning of the law of conservation of mass? mass of reactants ≥ mass of products mass of products ≤ mass of reactants mass of reactants ≠ mass of products mass of products = mass of reactants

mass of reactants = mass of products

Explanation:

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.

mass of hydrogen= 4 g

Mass of oxygen = 32 g

mass of water =

Thus mass or reactants =

Mass of hydrogen + mass of oxygen= 4+32= 36 g

Mass of product = mass of water = 36 g

Thus the total mass of reactants is equal to the total mass of products.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
