A solution at pH 7 contains how many times more hydrogen than a solution at a pH of 10?

Answers

Answer 1

Answer:

Answer:

Solution of pH 7 contains thousand times more hydrogen than the solution of pH 10.

Explanation:

pH of A substance is given by the negative of the logarithm of concentration of hydrogen ions. It is given by the equation

$pH=-log \ [H^+ ]$

Here the initial pH is given as 7. We have to calculate the concentration of $H^+$ ions.

$7=- log[H^+ ] [H^+ ]=10^-^7$

The final solution has a pH 10. We have to calculate the concentration of $H^+$ in this case

$pH=-log[H^+ ] 10=-log [H^+ ][H^+ ]=10^-^1^0$

Next we have to calculate how many times more is the $H^+$ ion concentration in the solution of pH 7 when compared to the solution with pH 10.

$\frac {10^-^7}{10^-^1^0} =10^3=1000$

Thus the concentration of $H^+$ ion in the solution of pH 7 is 1000 times more than the solution of pH 10.

Answer 2

Answer:

Final answer:

A solution at pH 7 contains 1000 times more hydrogen ions than a solution at a pH of 10. This is due to the logarithmic nature of the pH scale where each unit difference equals a tenfold difference in hydrogen ion concentration.

Explanation:

The pH value of a solution is the negative logarithm base 10 of the concentration of Hydrogen ions in the solution. The difference in pH from 7 to 10 implies a ten-fold difference for each unit of pH, thus, a difference of three pH units indicates a difference of 103, or 1000 times in hydrogen ion concentration. Therefore, a solution at pH 7 contains 1000 times more hydrogen ions than a solution at a pH of 10.

As a side note, it is important to remember that a lower pH value indicates a higher acidity (more hydrogen ions) and a higher pH value indicates a lower acidity (fewer hydrogen ions).

If birth rates fall below the replacement level, than a country is in which stage of demographic transition?

Answers

Answer:

Fourth Stage

Explanation:

During the fourth stage of demographic transition, the birth rates with in a population fall below the level of replacement and thus the population of such countries starts shrinking. This was once a common scenario in countries like Japan, Italy and Germany. The economy sees a down fall as the ageing population increases with no replacement of it in near by future.

Mostly the developed nations after the post industrial age are facing this situation.

Fat-soluble hormones pass through the cell membrane easily. Such hormones are referred to as _________________.

Answers

Answer:

Steroid hormones

Explanation:

Steroid hormones are the second largest groups of hormones. They are made up of small cholestrol units and are fat soluble, therefore they can pass easily through cell membranes.

Function:

They have roles in many vital functions of our body such as salt and water balance, formation of sexual traits,immunity related functions,metabolism and improving health by withstanding injuries.

Mode of action:

Steroids being hormones can effect the processes of body in two ways: They affect the transcription of genes involved in synthesis of certain proteins- this is called genomic level action.
They can affect by binding with specific membrane receptors like G-proteins, Ion channels and transporters- non genomic level function. Through these ways, they can affect many mechanisms occurring inside the cell.

Decomposersbreak downplant and animal waste products - To obtain energy

Decomposers obtain nutrients and energy by breaking down dead organisms and animal wastes.

decomposers release nutrients, such as carbon and nitrogen, back into the environment.
These nutrients are recycled back into the ecosystem so that the producers can use them.
