How do balanced chemical equations show the
conservation of mass?
O They show that the atoms in the products
may be different than the reactants as long
as the mass does not change.
They show that the atoms in the products are
the same as in the reactants, but the number
of atoms must change.
They show that the number of atoms of each
element is the same in the products and
reactants.

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
