Explanation:
Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound.
The correct type of heat transfer for A, B, and C are conduction, convection and radiation respectively.
<h3>What is heat transfer?</h3>
Heat transfer is a process in which amount of heat will be transferred from one object to any other object by various means.
- In type A, heat is transferred through conduction process as in this transfer takes place due to direct contact of particles.
- In type B, heat is transferred through the convection process as in that process transfer of heat takes place through the medium.
- In type C, heat transfer done by the radiation as in that transfer through empty space.
Hence at A, B and C heat transfer done through conduction, convection and radiation respectively.

Answer: The pressure in the can is 4.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 0.410 L
n = number of moles = 
R = gas constant =
T =temperature =
Thus the pressure in the can is 4.0 atm
Sodium is categorized as a B. Element.
