Methane and sulfur react to produce carbon disulfide (CS₂), a liquid often used in the production of cellophane.
Anestetic [448]

Answer:

9 moles

Explanation:

The balanced chemical equation provided in this question is as follows:

2CH₄ + S₈ → 2CS₂ + 4H₂S

In accordance to the above balanced equation, 1 mole of sulphur (S8) produces 4 moles of hydrogen sulfide (H2S).

Therefore, if 2.25mol of S8 is used, 2.25 × 4 = 9 mol

9 moles of H2S is produced.

Explain how to use the periodic table to deduce the number of protons, neutrons and electrons of an atom of a specific element
Ksju [112]

Answer:

See explanation

Explanation:

The periodic table shows the atomic number and mass number of each element.

We know that the atomic number shows;

  1. The number of protons in the nucleus of the atom
  2. The number of electrons in the neutral atom of the element.

So we obtain the number of protons and electrons by looking at the atomic number shown in the periodic table.

We also know that;

Mass number = Number of protons + number of neutrons

Since number of protons = atomic number of the atom

Number of neutrons = Mass number - atomic number

Hence we obtain the number of protons by subtracting the atomic number from the mass number given in the periodic table.
