How many kilojoules of heat are required to melt a 10-g popsicle is 0°c ? assume the particle has the same molar mass and heat of fusion as water.

3.4 kJ

Taking the mass of water as 10.0 g

Moles of water = Mass /molar mass

Moles of water in 10.0 g;

= 10g H2O x 1mol/18g

=0.56mol

But, 1 mole of water = 6.01 kJ

Hence;

6.01kJ/1mol H2O= x kJ/.56mol,

               x = 3.4kJ

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
