1. Energy in foods is provided by

Chemistry
1 answer:
ELEN [110]4 years ago
8 0

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.

Which pair of elements is most apt to form an ionic compound with each other?
sweet [91]
Ionic compounds are compounds that are formed together by a cation and an anion. A cation is an ion with a positive charge. For example, Na+ and Ca2+. An ion has a negative charge, like Cl- and OH-. There is a greater chance of forming an ionic compound when they have a great difference in electronegativity, the ability to attract electrons toward itself. In the periodic table, elements that are opposite to each other, more likely found in opposite sides, would be more apt to form an ionic compound. Example would be NaCl and CaCl2 or Ca(OH)2.

What would happen if you added more than 5ml of H2O2 to the 5ml of yeast
anzhelika [568]

Hydrogen peroxide breaks down into water and oxygen.


2H₂O₂ → 2H₂O + O₂


The yeast present contains an enzyme called catalase which catalyses the reaction.


More the amount of the catalyst added, faster will be the decomposition of the hydrogen peroxide.


Thus if we added more than 5 mL of yeast solution to the 2H₂O₂, the breakdown would occur faster. Thus the bubbles and the accompanying fizz would be much more.
