Chemistry

Answer:  Neutral Value

Explanation:  pH of the blood is maintained at 7.0 to 7.5that is neutral value.

This is because if the pH of the is lower than the maintained value then it will become acidic .

Acidic pH can cause the medical urgency known as acidosis leading to vomiting, diarrhea etc.

If the pH becomes higher, then the blood will become basic in nature and it can also leas to the death of the person.

That is why the pH of the blood is maintianed at neutral value of 7.0 to 7.5

Blood PH is kept near a value of 7.3 - 7.5 because of buffers.

Many of the cells in the body can only function within a range near a neutral PH, some of the enzymes responsible for production and growth, and breaking down the food we consume and help in other important function within the human body works within a certain PH range.

<h2>Further Explanation</h2>

The buffers, which are present in almost the entire living solution helps to maintain this PH.  

The blood is made up of large amount of carbonic acid, bicarbonate, a weak acid and a base. Together they assists in maintaining the blood level at 7.4. However, a higher or lower PH level can be very dangerous.

If the blood PH level is below 6.8 or above 7.8, individual can fall sick or even die. The presence of bicarbonate in the blood helps to neutralizes excess acid while carbonic acids help to neutralizes excess bases.

Any substance that minimizes or stops massive changes in PH is called a buffer. Every buffer has a particular buffer capacity and range. The buffer capacity is the amount of base or acid that is added to the PH level before it changes significantly while the buffer range refers to the PH range where a buffer neutralizes the acid and base that is added effectively.

Which of the following is the simplest ketone used as an organic solvent?
Lyrx [107]

Answer: Option (d) is the correct answer.

Explanation:

A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.

For example, acetone CH_{3}-CO-CH_{3} is a ketone.

Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}.

A camphor is a volatile white color substance with chemical formula C_{10}H_{16}O. It has aromatic smell and its taste is bitter.

A menthone is also an organic compound with chemical formula C_{10}H_{18}O.

Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.

There is about 1.0 g of calcium as Ca2+ in 1.0 L of milk. What is the molarity of Ca2+ in milk?
meriva

Explanation:

It is known that molarity is the number of moles present in a liter of solution.

           Molarity = \frac{\text{no. of moles}}{volume}

Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.

               No. of moles = \frac{mass}{\text{molar mass}}

                                     = \frac{1.0 g}{40.07 g/mol}

                                     = 0.025 mol

Therefore, calculate the molarity as follows.

             Molarity = \frac{\text{no. of moles}}{volume}

                            = \frac{0.025 mol}{1.0 L}  

                            = 0.025 M

Thus, we can conclude that molarity of Ca^{2+} in milk is 0.025 M.

Explain why some parts of our planet have very little seasonal change.
rosijanka [135]
Some parts of the planet undergo very little seasonal change due to their proximity to the equator and the poles. This means that their position relative to the sun and the earth's rotation varies hardly at all.
