Oxygen and Sulfur are in the same group.
Sulfur is the next element in the group, and it reacts with hydrogen gas (H2) in a manner similar to oxygen.
Answer: There are 0.006 moles of acid in the flask.
Explanation:
Given:
= 21.35 mL,
= 0.150 M
= 25.0 mL,
= ?
Formula used to calculate molarity of
is as follows.

Substitute the values into above formula as follows.

As molarity is the number of moles of a substance present in a liter of solution.
Total volume of solution = 
= 21.35 mL + 25.0 mL
= 46.36 mL (1 mL = 0.001 L)
= 0.04636 L
Therefore, moles of acid required are calculated as follows.

Thus, we can conclude that there are 0.006 moles of acid in the flask.
Because it helps enriches the soil, just like when you make home made compost you add egg shells and old veggies and stuff all the vitamins enriches the compost.
Hope this helped.
The Water Biome has The most biodiversity. The Desert is diffrent from the Tundra Tundra and deserts both face a scarcity in water. Therefore, the vegetation found in either biome are adapted to live in such water-barren environments. The vegetation of the tundra is also resistant to cold temperatures and winds. ... Many succulents are found in a hot and dry desert.
