Answer : The correct option is, 8 protons, 8 neutrons, 8 electrons

Explanation :

Neutral atom means the atom contains same number of electrons and protons and there is no charge on atom.

The given neutral atom is, oxygen

The atomic number of oxygen = 8

As we know that the atomic number is equal to the number of electrons and also equal to the number of protons.

Number of electrons = Number of protons = 8

The atomic mass of neutral oxygen atom = 16

Number of neutrons = Atomic mass - Atomic number = 16 - 8 = 8

Number of neutrons = 8

Therefore, the neutral atom of oxygen have 8 protons, 8 neutrons, 8 electrons.

Find the percentage of mass in each of the element Ca ( HCO3)2 (Ca= 40, H = 1, O = 16, C= 35)​
Alex787 [66]

Answer:

% Ca = 24.69%

% H = 1.2%

% C = 14.8%

% O = 59.25%

Explanation:

The percentage by mass of each element can be calculated by dividing the mass of each element in the compound by the molar mass of the compound.

Molar mass of Ca(HCO3)2

Where; (Ca= 40, H = 1, O = 16, C= 12)

= 40 + {1 + 12 + 16(3)}2

= 40 + {13 + 48}2

= 40 + {61}2

= 40 + 122

= 162g/mol

- % mass of Ca = 40/162 × 100

= 0.2469 × 100

= 24.69%

- % mass of H = 2/162 × 100

= 0.012 × 100

= 1.2%

- % mass of C = 24/162 × 100

= 0.148 × 100

= 14.8%

- % mass of O = 96/162 × 100

= 0.5925 × 100

= 59.25%
