Lena [83]4 years ago

Caloric content is the amount of calorie (energy nutrients) present in a food. Carbohydrates, proteins and fats are the three macronutrients that make up all foods and they are the body’s sources of calorie. Some macronutrients contain more calories per gram than others and this is because proteins and carbohydrates foods contain 4 calories per gram while fatty foods contain 9 calories per gram. Potatoes and yam have the same amount of carbohydrate, so they contain the same number of calories. Alcohol contains 7 calories per gram.

Compare and contrast the two types of bonds
stepan [7]

Answer:

An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.

Explanation:

There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.
