11. Which is another way of saying the law of conservation of mass? Matter cannot be created or destroyed.
The mass of the reactants always equals the mass of the products,
the law of conservation of matter
all of the above

all of the above

Explanation:

The Law of Conservation of Mass states that matter is neither created nor destroyed. It also states that in a chemical reaction, the total mass of the reactants equals the total mass of the products.

The Law of Conservation of Matter states that matter can change form through physical and chemical changes but matter is conserved. The same amount exists before and after the change. Matter is not created or destroyed.

So the answer will be all of the above.

Hope that helps.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
