blsea [12.9K]

Answer:

D. increase of carbon dioxide

Explanation:

Breathing is automatic and is controlled subconsciously by respiratory center at base of brain. It continues during the time of the sleep and even when the person is not in conscious. Sensory organs in brain and in aorta and  the carotid arteries monitor blood and sense the oxygen and the carbon dioxide levels. <u>Usually, increased concentration of the carbon dioxide is the strongest stimulus for the breathing to occur more deeply and more frequently.  </u>

When carbon dioxide concentration in the blood is high, the brain increases the frequency and the depth of breaths.

Questions 36 and 37 refer to the following: During a laboratory activity, a student places 25.0 ml of HCIOaq) of unknown concent
Leto [7]
36)  HCl(aq)+KOH(aq)⇒H₂O(l)+KCl(aq)

37)  You can use the equation M₁V₁=M₂V₂
M₁=concentration of acid
V₁=volume of acid in orginal solution
M₂=concentration of base
V₂= the volume of based used to neutralize the acid
M₁=(0.150M KOH x 0.0185L KOH)/0.025L HCl
M₁=0.111M HCl
This equation works since we no based off of the formula in question 36 that 1 mole of KOH will neutralize 1 mole of HCl and <span>M₂V₂ is equal to the moles KOH which means it needs to equal M</span>₁V₁ since that is the number of moles HCl. (if moles HCl did not equal moles KOH the solution would not be neutralized).
