The Ideal Gas Law is expressed mathematically as
P1 /T1 = P2/T2
P1/V1 = P2V2
PV =nRT
PV =KT
V1/T1 = V2/T2
Correct answer is C
The empirical relationships among the volume, the temperature, the pressure, and the amount of a gas can be combined into the ideal gas law, PV = nRT.

The furring of kettles and boilers are caused by
calcium hydroxide
calcium hydrogen trioxocarbonate (IV)
calcium trioxocarbonate (IV)
calcium tetraoxocarbonate
magnesium tetraoxocarbonate (VI)
Correct answer is C
The furring of kettles or boilers - this is as a result of the decomposition of Ca(HCO3)2 into CaCO3, and this coats the inside of a kettle or boiler used in heating water containing dissolved Ca(HCO3)2.
