No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol
Mr of Na2O = 23+23+16 = 62 g/mol
n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol
m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g
It is called the nitrogen cycle- nitrogen gas gets transformed into nitrates through nitrogen fixation.
Answer is: C. CH3CHOHCH3.
Balanced chemical reaction of hydration of propene:
CH₃CH=CH₂ + H₂O → CH₃CHOHCH₃.
A hydroxyl group (OH⁻) attaches to one carbon of the double bond and a proton (H⁺) adds to the other carbon of the double bond according to Markovnikov's rule (hydrogen gets attached to the carbon with more hydrogen substituents).
Product of this reaction is propan-2-ol (isopropyl alcohol).
Each state is allocated a number of electors equal to the number of its U.S. Senators
