Answer:
Brittany is studying the properties of a sample of iron. Whether she studies a large sample or a small sample, the <u><em>properties</em></u> of iron will always be the same.
Explanation:
The properties of an element will always remain the same no matter if we change the quantity of the element.
Iron is a chemical element with atomic number 26. It belongs to group 8 of the periodic table.
The properties of iron are:
- It is a shiny metal.
- It is soft, malleable and ductile.
- It combines readily with oxygen in the air and hence can be rusty in the damp air.

Answer: 47.04 L will be the volume occupied by the 2.1 moles of nitrogen gas at STP.
Explanation:
At STP,
1 mol of ideal gas occupies = 22.4 L
Considering nitrogen gas to be an ideal gas
Then 2.1 moles of the nitrogen gas will occupy:
47.04 L will be the volume occupied by the 2.1 moles of nitrogen gas at STP.
