An example.
water is H2O
2 hydrogen, 1 oxygen
so the number to the right means how much of what is on the left.
so it looks like 2, because C2, but look at the 3 at the beginning. that means
3 (c2h4)
so 6 carbons, 12 hydrogen
the ratio of c2 to h4 doesn't change it's always 1:2.
but the 3 at the front is a different number relating to how much you have

Answer:
a) Mg and S = atoms
b) H2 SO3 = molecules
c) HBr =molecule
Explanation:
Step 1: Data given
Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.
Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
a. Mg S = Magnesium and sulfur both are atoms, we both can find them on the periodic table
b. H2 SO3 = H2 is a molecule that contains 2 hydrogen atoms
SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms
c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom
Answer:
The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun's light, making it appear bright in our sky. Have your child hold the fruit at arm's length, pointing at the light.
hope this helps :)
