Answer:
neutralization reaction is when an acid and a base react to form water and salt and involves the combination of hydrogen ions and hydroxyl ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Explanation:
Methane and sulfur react to produce carbon disulfide (CS₂), a liquid often used in the production of cellophane.
2CH₄ + S₈ --> 2CS₂ + 4H₂S
Calculate the moles of H₂S produced when 2.25 mol S₈ is used.
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.

What is created when an acid is mixed with a base?
Answer:
If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution.

How many moles of aspirin (C9H8O4) are contained in 3.13 g of aspirin?
Answer:
The correct answer is - 0.0173888 moles.
Explanation:
Aspirin, C 9 H 8 O 4 , the atomic mass rounded to the nearest whole number, so: c- 12 h- 1 o - 16
now multiply these number by how many of each there are in the formula:
c - 12 x 9 = 108
h - 1 x 8 = 8
0 - 16 x 4 = 64
add these numbers up 108 + 8 + 64 = 180
aspirin has a molar mass of
180.g mol ^− 1 . This means that one mole of aspirin will have a mass of 180 g .
You're dealing with 3.13 g of aspirin, which will be equivalent to
3.13 g /180g
= 0.0173888 moles aspirin
