Answer: I believe it’s the second one
(F)
Explanation:
Atoms have no electric charge because the protons and electrons "cancel out" each others charges. Neutrons have no charge. What is the atomic number of an element? The atomic number is the number of protons in the atom's nucleus.

You have to calculate the heat for three separate processes:1) heat the ice from - 12°C to 0°C, 2) melt the ice at 0°C, and 3) heat the liquid water from 0°C to 27.0 °C.
1) Heating the ice from - 12°C to 0°C
Q1 = m * C * ΔT = 5.88g * 2.09 j/g°C * [0°C - (-12°C) ] = 147.47 j
2) Melting the ice at 0°C
Q2 = m * Δh fus
Convert 5.88 g to moles => 5.88 g / 18.0 g/mol = 0.327 moles
Q2 = 0.327 moles * 6.02 kj / mol = 1.96653 kj = 1966.53 j
3) Heating liquid water from 0°C to 27.0 °C
Q3 = m * C * ΔT
C = 4.1813 j/g°C
Q3 = 5.88 g * 4.1813 j/g°C * (27.0°C - 0°C) = 663.82 j
4) Total heat, Q
Q = Q1 + Q2 + Q3 =147.47j + 1966.53 j + 663.82 j = 2777.82 j ≈ 2778 j
Answer: 2778 j
