The following are 1.0 M acid solution, which has the largest concentration of hydronium [H3O+]?A. HNO2

B. H2CO3

C. H2SO4

D. H3BO3

Answers

Answer 1
Answer: H2SO4 has the largest concentration of hydronium [H3O+] because H2SO4 is a strong acid.
Answer 2
Answer:

Answer: Option (C) is the correct answer.

Explanation:

An acid which is able to dissociate completely into ions in water is known as a strong acid.

For example, H_(2)SO_(4) \rightleftharpoons 2H^(+) + SO^(2-)_(4)

Therefore, sulfuric acid is a strong acid as it dissociates completely into ions in water.

Whereas HNO_(2), H_(2)CO_(3), and H_(3)BO_(3) are all weak acids as they dissociates slightly in water as follows.

H_(3)BO_(3) \rightleftharpoons H^(+) + H_(2)BO^(-)_(3)

HNO_(2) \rightleftharpoons H^(+) + NO^(-)_(2)

H_(2)CO_(3) \rightleftharpoons H^(+) + H_(2)CO^(2-)_(3)

Morover, sufuric acid upon dissociation is giving 2 hydrogen ions and rest all are giving one hydrogen ion.

Thus, we can conclude that out of the given options H_(2)SO_(4) has the largest concentration of hydronium [H3O+].

If the earth's differentiation were any different, it may have affected its gravitational pull and . Both of these factors were essential to creating our atmosphere.

Answers

If the Earth's differentiation were any different, it may have affected its gravitational pull and tectonic activity. First, it must be clarified that differentiation refers to the geological process that resulted in the Earth's interior structure. This means that tectonic activity such as volcanic activity are also essential to creating our atmosphere by participating in the various atmospheric cycles.

The statement "white blood cells can leave the blood circulatory system" is definitely true.

What is the circulatory system?

The circulatory system may be defined as a type of body system that significantly contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.

White blood cells can also be known as the soldiers of the body. They can leave the bloodstream and migrates into tissues in the body. White blood cells play an important role in the immune system.

Here the different blood cells have different functions: Some fight intruders such as bacteria, viruses, parasites, or fungi themselves and render them harmless.

Various studies and reports suggested that the white blood cells -- actively open large gaps in the internal lining of the blood vessels, so they can exit through the vessel walls and rapidly get to areas of infection.

Therefore, the statement "white blood cells can leave the blood circulatory system" is definitely true.
