I don’t know off the top of my head but just look at a periodic table (most elements are metal anyway)
Answer: Reactants and Products
Explanation:
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Answer:
heat and large amount of surface area
Explanation:
the heat and surface area allows the iron in the wool to combine with oxygen. by doing this it increases the mass of the steel wool

Explanation:
The internet told me
Answer:
The pressure of the gas increased (if temperature remained constant).
The Boyle's law supports this observation.
Explanation:
The initial measurements of the gas are given as;
volume = 100 L
Pressure = 300 kpa
The second measurement is given as;
Volume = 75 L
The second reading implies that the volume of the gas has decreased. If the temperature of the gas remained constant, then the pressure must have increased according to the Boyle's law;
At constant temperature, the pressure of a given mass of an ideal gas is inversely proportional to its volume.
