Answer:
runoff is he draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.
Explanation:
Answer:
Explanation:
The structural formula provides more information which is often used to represent a particular organic substance. A structural formula indicates how the atoms are arranged within the molecule of a substance. From the information, the structure of 4-methyl-5-oxohexanal is represented by using a stick formula where the methyl group falls into position 4 and oxygen group falls into position 5 on the hexanal compound.
The structure is provided in the image attached below for better understanding.
Answer: The
of a solution is
M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in ml
moles of
= 
Now put all the given values in the formula of molality, we get

pH or pOH is the measure of acidity or alkalinity of a solution.

According to stoichiometry,
1 mole of
gives 1 mole of
Thus
moles of
gives =
moles of
Putting in the values:
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[0.01][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5B0.01%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[OH^-]=10^{-12}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-12%7D)
Thus the
of a solution prepared by dissolving 0.0912 g of hydrogen chloride in sufficient pure water to prepare 250.0 ml of solution is
M
