The atom that is made up of two protons is He. The number of neutrons is also two. The number of electrons matters in the charge. So to make 10 electrons, we add 8 more. hence, 4/2 He 8-.

Explanation:
2.600 × 10^-5 × 6.100 × 10^-5 = 1.586 × 10-9
Fe+CuSO4⟶Cu+FeSO4
Given that
FeSO4 = 92.50 g
Number of moles = amount in g / molar mass
=92.50 g / 151.908 g/mol
=0.609 moles FeSO4
Now calculate the moles of CuSO4 as follows:
0.609 moles FeSO4 * 1 mole CuSO4 /1 mole FeSO4
= 0.609 moles CuSO4
Amount in g = number of moles * molar mass
= 0.609 moles CuSO4 * 159.609 g/mol
= 97.19 g CuSO4

Answer:
The events in the rock cycle can be divided into categories:
a) Surface Events
These are the changes that occur on the surface of the earth. This includes weathering and erosion
Igneous Rocks
b) Subsurface Events
These are the changes in the cycle that occur in the inner surface of our planet. This is under the surface of Earth. This includes process like plate tectonics and mountain building.
Sedimentary
