Answer:
1. 
2. 
Explanation:
An ion is formed when an atom that is said to be neutral gains or losses electrons.
It is thought that a negative ion (anion) is produced as it gains electrons and a positive ion (cation) is formed when it loses an electron.
Atomic number is the total number of protons and electrons in a neutral atom.
From the information
Protons = 14
electron = 18
Net Charge = no of proton - no of electron
= 14 - 18 = -4
Mass number = 14 + 15 = 29
Thus, the chemical symbol =
For ion with 27 proton, 32 neutrons and 25 electrons
Net charge = 27 - 25 = +2
Mass number = 27 + 32 = 59
Thus, the chemical symbol =

Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.
Answer:
Heating the CuSO4. 5H2O crystals causes then to loose the water of crystallisation that is the 5H2O part. It becomes anhydrous copper sulphate. Its colour changes to white from blue.
