It is produce by the carbonylation of methanol. Carbon monoxide and methanol react to form acetic acid.

chemical equation:

CH3OH + CO → CH3COOH

This process complete in three steps:

CH3OH +H1 → CH3I + H2O

CH3I + CO → CH3COI

CH3CO1 + H2O → CH3COOH + HI

Physical properties of acetic acid:

It is colorless liquid.
It has pungent odor.
Its molar mass is 60.052 g/mol
Its density is 1.05 g/ml.
Its boiling and melting points are 118°C and 16.6°C respectively.

Uses of acetic acid:

It has antiseptic properties and used in medicine.
It is also used in medicine for ear which is used for bacterial infection.

A taco from a fast food restaurant contains 7.0 g of fat, 25. g of carbohydrate, and 11 g of protein. How many kJ of energy does

Gennadij [26K]

Answer: 878 kJ of energy is there in cheeseburger

Explanation:

Given : calorific value of fat = 38kJ/g

calorific value of carbohydrate = 17 kJ/g

calorific value of protein = 17kJ/g

1 g of fat contains energy = 38 kJ

7.0 g of fat contains energy = $\frac{38}{1}\times 7.0=266 kJ$

1 g of carbohydrate contains energy = 17 kJ

25 g of fat contains energy = $\frac{17}{1}\times 25=425kJ$

1 g of protein contains energy = 17 kJ

11 g of protein contains energy = $\frac{17}{1}\times 11=187kJ$

Total energy = (266+425+187) kJ = 878 kJ
