Chemistry topic: soaps and detergents
formulate the equation for obtaining a soap: sodium oleate
formulate the equation for obtaining a detergent: sodium sulphonate
how soaps and detergents differ
for answer any of those questions, i am going to give you the correct answer

Here's what I find  

Explanation:

A. Sodium oleate

You make sodium oleate by neutralizing oleic acid with sodium hydroxide.

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH=CHCH₂CH₂CH₂CH₂CH₂CH₂CH₂COOH + NaOH ⟶ CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH=CHCH₂CH₂CH₂CH₂CH₂CH₂CH₂COOH + H₂O

B. Sodium alkylbenzenesulfonates

Sodium dodecylbenzenesulfonate is prepared by the neutralization of dodecylbenzenesulfonic acid with sodium hydroxide.

CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂C₆H₄SO₂OH + NaOH ⟶ CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂C₆H₄SO₂ONa + H₂O

C. Difference between soaps and detergents

(i) Soap

(ii) Detergent

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.
