Almost all plants and animals go through either photosynthesis or respiration!
First write a balanced equation...
P4 + 5 O2 ⇒ 2P2O5
mole of P4 = 136 ÷ (4×31) = 1.09677
MOLE RATION OF P4 : P2O5 IS 1:2
THAT IS 1 mole of p4 reacts to give 2 moleof p2o5
∴ 1.09677 mole............................. (2×1.09677) =2.19....mole
maximum number of mole = 2.19 mol
Polarity occurs in a Hydrogen Bond
Let the hydrated compound be CaSO4.xH2O
mass of the caso4= 43.63g /(40+32+64+18x)* (40+32+64)= 36.45g
136+18x=( 43.63*136) / 36.45= 162.78
18x = 162.78- 136= 26.8
x = 1.48 = 1.5
Formula of hydrate = CaSO4.1.5H2O = 2CaSo4. 3H2O
