Answer:
The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in
the products
Explanation:
For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass

Answer:
See explanation
Explanation:
The postulates of the kinetic theory of matter are;
- Every substance is made up of tiny particles called molecules. Brownian motion and diffusion illustrates this fact.
- The molecules that compose matter are in constant random motion.
- There exists an attractive force between the molecules in matter. The attractive forces between gases are negligible. Solids have a definite shape and volume due to a high magnitude of intermolecular forces. Liquids have a volume but no definite shape due to weaker intermolecular forces. Gases have the weakest intermolecular forces hence the do not have both a shape and volume. They take on the volume of the container into which they are put. This illustrates this fact.
- The actual volume occupied by gas molecules is negligible relative to the volume of the container. The fact that gases are easily compressible illustrates this fact.
- Temperature is a measure of the average kinetic energy of the molecules of a body.
Answer:
the answer is d only as
ca reacts
mg reacts
k is more reactive so no reaction
mg is less reactive than sodium
