Nutrition is defined as the processes by which an animal or plant takes in and utilises food substances. Essential nutrients include protein, carbohydrate, fat, vitamins, minerals and electrolytes. Normally, 85% of daily energy use is from fat and carbohydrates and 15% from protein.
Answer:
7 = c) CO because all others are ionic compounds .
8 = b) H-F because Ionic character depends on the electronegativity difference between the bonding elements. The greatest the electronegativity difference the greatest the ionic character.
9 = d) H2O
the next most abundant is the robust sounding "protonated molecular hydrogen", or H3+. As the name implies, H3+ is ordinary old molecular hydrogen with an extra proton, making a stable but highly reactive (and acidic) structure.
10 = d) Na-I because, I is an electronegative element and comparitively small and Na is having a large size.
covalent nature is less among them.
11 = c) CO The bond formed between any two atoms is not a purely ionic bond. All bonding interactions have some covalent character because the electron density remains shared between the atoms. Bonds that fall in between the two extremes, having both ionic and covalent character, are classified as polar covalent bonds.
