N: Calculate the mass percent of each element in Na2S.

Chemistry
1 answer:
Goryan [66]3 years ago
5 0

Answer:

NaS2 has two elements within: Sodium & Sulfur.

Basically, the mass percentage of Na2S is:

Sodium = 58.914%

Sulfur = 41.086%

In total, that would equal: 100%.

Explanation:

Well, we know this because Na (Sodium) has 2 atoms & Sodium has no number after it so, that would be an ordinary one atom.

So, knowing that there are more Sodium's than Sulfur, the mass percentage would be higher, than the percentage of Sulfur.

How does anaerobic respiration occur in yeast ?
slavikrds [6]
When there isn't enough oxygen for Oxidative Phosphorylation to occur, anaerobic respiration occurs. You can't produce ATP across the inner of the mitochondrial membrane or in the Krebs cycle if you don't have Oxidative Phosphorylation. As a result, the yeast employs anaerobic respiration to keep Glycolysis running, resulting in 4 ATP molecules (Net: 2) each Glucose molecule that is converted to Pyruvate.

Allowing NADH to lose hydrogen allows it to be converted to NAD, which can then be utilized to oxidize glucose to pyruvate, which produces ATP, and so on. This is best illustrated in a diagram, in my opinion.

If the H3O is 4.950 x 10-12 what is the ph?
romanna [79]

Answer:

pH = 11.3

Explanation:

From the question given above, the following data were obtained:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

The pH of a solution is defined by the following equation:

pH = –Log [H₃O⁺]

Thus, with the above formula, we can obtain the pH of the solution as follow:

Concentration of hydronium ion [H₃O⁺] = 4.950×10¯¹² M

pH =.?

pH = –Log [H₃O⁺]

pH = –Log 4.950×10¯¹²

pH = 11.3

Which formula equation represents the burning of sulfur to produce sulfur dioxide?
Firlakuza [10]

Balanced chemical equation: S(s) + O₂(g) → SO₂(g).

Sulfur change oxidation number from 0 to +4 (oxidation) and oxygen change oxidation number from 0 to -2 (reduction).

Sulfur dioxide (SO₂) is very common volcanic gas.

Fossil fuel combustion increases the acidity of rain because the sulfur dioxide is produced.  

Because of fuel combustion, sulfur dioxide goes up into the atmosphere as the hot gases rise, than it reacts with water and oxygen in the air and form sulfuric acid.
