A. 11/3kg
B. 3/11
C. 4/3kg
D. 3/4kg
Correct option (a) 11/3 kgExplanation:C + O2 → CO2 12 g of C gives 44 g of CO2 1 g of C = 11/3 g of CO2 1 kg of C = 11/3 kg CO2
Correct option (a) 11/3 kg
Explanation:
C + O2 → CO2
12 g of C gives 44 g of CO2
1 g of C = 11/3 g of CO2
1 kg of C = 11/3 kg CO2

A. Energy can be created as well as destroyed.
B. Energy can be created but not destroyed.
C. Energy can neither be created nor destroyed.
D. Energy cannot be created but can be destroyed.
Correct option (c) Energy can neither 'be created nor destroyedExplanation:In physics, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather,Read more
Correct option (c) Energy can neither ‘be created nor destroyed
Explanation:
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time.
This law means that energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.

Correct option (b) Nucleic acids
Explanation:
Gout is a type of arthritis, an inflammatory condition of the joints. Gout symptoms or “attacks” occur when there is too much uric acid in the blood. Uric acid is a waste product made by the body when it digests certain foods. Fortunately, research shows that restricting high-purine foods and taking the appropriate medication can prevent gout attacks.
Gout patients should avoid meats such as liver, kidney and sweetbreads, which have high purine levels and contribute to high blood levels of uric acid.
