Why do the particles of objects have both kinetic and potential energy?  
OLEGan [10]
The particles of objects have both kinetic and potential energy because these forces are drive by the force of motion or stillness of an object. Potential energy is the a type of energy which an object possess however without motion. Kinetic energy in the other hand, is the energy in motion or if the object moves along from one space to another with respect to time. They both have these two energies by the presence of atoms in these entities.

How many atoms are there in 32.45 grams of Magnesium?
levacccp [35]

Answer:

8.13 ×10²³ atoms

Explanation:

Given data:

Mass of magnesium = 32.45 g

Number of atoms = ?

Solution:

Number of moles of Mg:

Number of moles = mass/molar mass

Number of moles = 32.45 g/ 24 g/mol

Number of moles = 1.35 mol

Number of atoms:

1 mole contain 6.022×10²³ atoms

1.35 mol × 6.022×10²³ atoms/ 1mol

8.13 ×10²³ atoms

The polymerization of amino acids produces:
Delicious77 [7]

Answer:

Proteins

Explanation:

Polymerization, in chemistry, is the chemical combination of monomeric units to form a polymer. Polymers are large molecules made up of smaller units called monomers. Amino acids are the monomeric units of proteins i.e. A protein is made up of of many amino acids joined together.

Therefore, the chemical combination of amino acids will form a peptide bond between the carbon atom of the acid group and nitrogen atom of the amine group in the structure of the amino acids. This is done by the loss of a water molecule. The continuous repetition of this polymerization process will form a chain called polypeptide, which is the PROTEIN.
