Energy change = -303050 J

Explanation:

the heat energy Q is given by the formula

Q= m C ΔT

m= mass of water=1.25 Kg

C= specific heat of water= 4180 J/Kg °C

ΔT= change in temperature =55-113= -58°C

Q= 1.25 (4180) (-58)

Q=-303050 J

Negative sign shows that the energy is released or lost.

Which statement is true about crystal lattice energy?
irinina [24]

The answer is:

It is a measure of the strength of the bonds between ions.

Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.

The first two choices are wrong because it is actually the opposite.

  • As the ion size increases, lattice energy <u>decreases</u>.
  • As charge of ions increases, lattice energy <u>increases</u>

As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.
