Answer:

protons and neutrons

Explanation:

An atom is said to be the simple units of matter and basic of describing elements structure. An atom of an element have protons , neutrons and electrons.

The protons and neutrons of an atom are usually located in the nucleus of an atom. The sum of the proton and neutron of an atom determines the atomic mass of an element. This means the proton and neutron plays a major role in determining the mass of an atom. The proton is usually positively charge and tends to repel each other in the nucleus of an atom. The neutron has no charge but usually possess more weight than the proton.

The electron is located at the outer parts of the atom. it usually revolve round the atom . The electron determines how the atoms of an elements bond with other atoms. For an electronic neutral charge of any atom the proton number is equal to the electron number.  

The picture above illustrate how the proton, neutron and electron reside in the atom.

Answer the following questions about the fermentation of glucose (C6H12O6, molar mass 180.2 g/mol)
Yuri [45]

The amount of energy in kilocalories released from 49 g of glucose given the data is -4.4 Kcal

How to determine the mole of glucose

Mass of glucose = 49 g

Molar mass of glucose = 180.2 g/mol

Mole of glucose = ?

Mole = mass / molar mass

Mole of glucose = 49 / 180.2

Mole of glucose = 0.272 mole

How to determine the energy released

C₆H₁₂O₆ →2C₂H₆O + 2CO₂  ΔH = -16 kcal/mol

From the balanced equation above,

1 mole of glucose released -16 kcal of energy

Therefore,

0.272 mole of glucose will release = 0.272 × -16 = -4.4 Kcal

Thus, -4.4 Kcal were released from the reaction
