The  amount of heat required   is calculated  using the below  formula

Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)

change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g

Q= 54.0 g x 2.48 j/g/k x 10k  = 1339.2  joules is required

What's the difference between formula mass, molecular mass, and gram formula mass?
marissa [1.9K]
MASS: generally a measure of an object's resistance to changing its state of motion when a force is applied. It is determined by the strength of its mutual gravitational attraction.

Molecular mass or molecular weight is the mass of a molecule.

Gram formula mass (a.k.a. molar mass) is defined as the atomic mass of one mole of an element, molecular compound or ionic compound. The answer must always be written with the unit g/mol (grams per mole).

The increase in atomic radius as you go down the periodic table is caused by?​
Kryger [21]

Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.
