The total heat required to convert the ice to steam is 155,000 J.
The given parameters:
- <em>Mass of the ice, m = 50 g</em>
- <em>Initial temperature of the ice, t = -10 ⁰C</em>
- <em>Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C</em>
- <em>Specific heat capacity of water = 4.184 J/g⁰C</em>
- <em>Heat of fusion of ice, = 333.55 J/g</em>
- <em>Heat of vaporization, = 2,230 J/g</em>

Was there supposed to be a picture attached?
Answer:
HNO2
Explanation:
It is a pale blue solution and it is only known in solution and gas form.
The chemical formula is:
NiCO4
We see from the formula that there are 4 moles of Oxygen
(O) per 1 mole of Nickel (Ni). Therefore the moles of Oxygen in the sample is:
moles O = 9.55 moles Ni * (4 moles O / 1 mole Ni)
moles O = 38.2 moles O
