B- Carbon nitrogen and oxygen. All organisms are made up of carbon, oxygen is essential to breath, and nitrogen makes up most of earth's atmosphere.
Explanation:
No. Different acids have different strengths . The amount of dissociation to H+ concentration , for the same concentration a strong acids would have a lower pH ( H+ concentration ) and a weak acid would have a higher pH ( lower H+ concentration )
Answer:
Mol. mass of ethyl alcohol =C2H5OH=46
No. of moles of ethyl alcohol =4660=1.304
Mol. mass of methyl alcohol =CH3OH=32
No. of moles of methyl alcohol =3240=1.25
′XA′, mole fraction of ethyl alcohol =1.304+1.251.304=0.5107
′XB′, mole fraction of methyl alcohol =1.304+1.251.25=0.4893
Partial pressure ethyl alcohol =XAp˙A0=0.5107×44.5=22.73mmHg
Partial pressure methyl alcohol =XBp˙B0=0.4893×88.7=73.40mmHg
Total vapour pressure of solution =22.73+43.40=66.13mmHg
Mole fraction of methyl alcohol in the vapour
=Total vapour pressurePartial pressure of CH3OH

The substance will not sink in water, as it Dencity is (0.5)is less than the density of water (1gcm).
Answer:
Structure of the product has been shown below
Explanation:
- N atom in aniline acts as a nucleophile and carbonyl group of propanoic acid acts as an electrophilic center.
- A nucleophilic acyl substitution reaction occurs on mixing and heating mixture of aniline and propanoic acid.
- In this reaction an amide is formed.
- Reaction mechanism goes through addition-ellimination pathway at carbonyl center.
- Full reaction mechanism has been shown below.
