Answer:
Found within living cells to produce protein (protein synthesis).
Answer:
1.) The aluminum block
2.) more than the nail it came from
3.) Rust contains iron and oxygen
Explanation:
1.)
Mass, Density, and Volume are related by the following equation;
Mass = Volume*Density
Solving for volume;
Volume = Mass/Density
If Mass is constant then;
Volume ∝ 1/Density ; That is volume and density will be inversely proportional. The larger the volume the smaller the density
2.)
If an iron nail were allowed to rust completely, you should find that the rust weighs more than the nail it came from since Iron combines with oxygen and water from the air to form rust.
3.)
Rust contains iron and oxygen.
Rust is composed or made up of hydrated iron(III) oxides Fe2O.
