Mass : actual amount of material contained in a body. It is independant of where you are.
Weight: force that gravity puts on a mass.
On Earth, gravity is 9.80 m/s^2compared to 1.62 m/s^2 on the moon.
Weight=mass *gravity
Moon : (example)
10 kg* 1.62 m/s^2= 16.2 N ( Newton is the unit for weight)
Earth:
10*9.80= 98 N
9.0 grams will produce 11 L of hydrogen

Answer: C) Gold
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Gold
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water
, butanal , and propene
For example:
Thus the element gold can not be broken down by a chemical change.
