First of all, we convert the amount of item given in moles into grams. Each mol of steam is 18 grams of steam. Such that the heat released during the evolution of per gram of steam is,
H = (2.01 J/goC)(160 - 100) + 2260 J/g + (4.179 J/gC)(100 - 0) + (333.5 J/g) + (2.09 J/gC)(45oC)
H = 3226.05 J/g
Then, we multiply this value by 18 g to get the final answer which is equal to 58068.9 Joules.

Answer:
⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga
Explanation:
Nuclear reactions are reactions which occur with changes in the nucleus of an atom. Nuclear reactions usually occur with the release of large amounts of energy and radiation. Radiactive elements are elements that are involved in nuclearbreactions due to the unstable nature of their nucleus. They disintegrate spontaneously with the emission of radiations. The major types of radiations released during nuclear reactions are;
1, Alpha particles - these are positively charged radiations with strong ionizing power. Each alpha particle is a helium nucleus
2. Beta particles - these are very fast moving stream of electrons. They are negatively charged particles .
3. Gamma radiation - is a form of electromagnetic radiation.
In the alpha absorption of Cu-61, the proton number of the atom increases by 2 while the mass number increases by 4 and the Cu-61 atom is changed to Ga-65 atom. The nuclear equation is given as follows:
⁶¹₂₉Cu + ⁴₂He --->⁶⁵₃₁Ga
