Answer:
2 mol NO2
Explanation:
3NO2(g)+H2O(l)→2HNO3(l)+NO(g)
from reaction 3 mol 1 mol
given 11 mol 3 mol
for 3 mol NO2 ----- 1 mol H2O
for x mol NO2 ----- 3 mol H2O
3:x = 1:3
x = 3 *3/1 = 9 mol NO2
So, for 3 mol H2O are needed only 9 mol NO2.
But we have 11 mol NO2. So, NO2 is in excess, and
11 mol NO2 - 9 mol NO2 = 2 mol NO2 will be left after reaction.
1.123 * 10^3 thatsssss it
Answer:
Energy in foods is provided by macro-nutrients.
Explanation:
Nutrients are “environmental substances” used for growth, energy, and bodily functions of the organisms. Those nutrients that are required in larger amounts are called macro-nutrients.
There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in form of “calories”. For example:
- In carbohydrates, there are '4 calories' of energy per gram.
- In proteins, there are '4 calories' of energy per gram.
- And in lipids, there are '9 calories' of energy in one gram.
This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
