What does the name iron(ii) in a compound indicate about the cation?
bija089 [108]

Answer:- Fe^+^2

Explanations:- Transition elements shows variable oxidation states. So, while naming these compounds we use the roman numerals to tell their oxidation states.

For example, if someone writes just Iron oxide then it would not be correct since Iron could be in +2 or +3 states. So, it might be Fe^+^2 or Fe^+^3 . So, the right was is to mention the oxidation state of the transition metal.

If the name is written as Iron(II) in a compound then it means there is +2 charge on iron and it is Fe^+^2.

fomenos

Answer: Adiabatic process is a process in which <u>heat</u> is constant

Explanation:

The processes in which temperature remains constant is called isothermal process.

The process in which Volume remains constant is called isochoric process.  

The process in which pressure remains constant is called isobaric process.

 The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

Thus option d) heat is correct
