Question

Which statement is true for one molecule of sulfur trioxide?A.(There are three atoms of sulfur and one atom of oxygen.B.(There are three atoms of sulfur and three atoms of oxygen.C.(There is one atom of sulfur and one atom of oxygen. or D.(There is one atom of sulfur and three atoms of oxygen.

Answer 1

The answer would be D. This is because sulfur is on it's own, meaning one. while tri is a prefix for three so there are three oxygen atoms.

Answer 2

Answer: D. There is one atom of sulfur and three atoms of oxygen.

Explanation:

An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.

Element is a pure substance which is composed of atoms of similar elements. Example: Gold $Au$

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water $SO_3$

1 molecule of $SO_3$ is made up of one atom of sulfur and three oxygen atoms combined together in fixed ratio by mass.
