Chemistry
1 answer:
SCORPION-xisa [38]4 years ago
5 0

Answer:

2HCI + Na2S ----> H2S + 2NaCl

Explanation:

For a balanced chemical equation, the number of moles of atoms on the reaction side must equal the number of moles of atoms on the product side, in accordance with the law of conservation of mass.

The correct answer is:

2HCI + Na2S ----> H2S + 2NaCl

Since it has equal number of moles of each atom on both sides of the equation: 2 atoms each of hydrogen, chlorine, and sodium on both sides of the equation as well as 1 atom of sulphur on both sides of the equation.

The average mass of all fluorine (F) atoms is 18.998 u.Do you think most fluorine atoms have 9 neutrons or 10 neutrons? Explain.
hodyreva [135]

Answer:

10 neutrons

Explanation:

The mass of is made up of the total protons and neutrons in an atom.

Each particle has a mass of 1 amu (atomic mass unit).

All fluorine atoms have 9 protons.

If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).

This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).

If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).
