Answer: 240
Explanation:
A serving of fish contains 236 kcal.
To find the number of kilocalories (kcal) in a serving of fish, we need to calculate the energy from protein and fat separately and then add them together. The energy from protein is calculated by multiplying the amount of protein by its caloric value of 4 kcal/g. So, 50 g of protein provides (50 g) x (4 kcal/g) = 200 kcal. The energy from fat is calculated in the same way, so 4 g of fat provides (4 g) x (9 kcal/g) = 36 kcal. Finally, we add the energy from protein and fat together, resulting in a total of 200 kcal + 36 kcal = 236 kcal in the serving of fish.

The elements that can form acidic compounds are; sulfur, arsenic, selenium, antimony, silicon.
Acidic compounds are formed by nonmetals. Metallic elements form basic compounds. This means that rubidium does not form acidic compounds since it is a metal.
Also, xenon does not form compounds because it is a noble gas. Noble gases do not react with other elements to form compounds.
However; sulfur, arsenic, selenium, antimony, silicon are nonmetals and they form acidic compounds.

The correct answer is Sulfur, Arsenic, selenium, silicon, and antimony.
All fossil fuels contains hydrocarbons in it. Amongst the given options hydrogen is the correct answer. Except that it contains carbon in it. Hydrocarbons are those class of compounds which contains hydrogen and carbon as element in it.
They are considered to be good fuels because they naturally bring out complete combustion as they contain hydrogen and carbon in its compound form.
