Answer:
1 x 10^-12 mol dm^-3
Explanation:
[H+] = 10 ^ -pH
Therefore, pH 12 = 1 x 10^-12 hydrogen ion concentration
Hey there!
The correct answer to your question is a compound.
A substance of two or more elements chemically combined in a set ratio, or proportion, is called a compound.
This is because compounds are made of two or more elements. Table salt is an example of a compound because it is made up of the elements chlorine and sodium.
Hope this helps you.
Have a great day!
Answer: 6:50
Explanation:
I think that is correct is use the math correctly u could get 6:50 like i got or 7:00.
There can be two cases
Case 1:
When a molecule has one carbon-carbon double bond and four monovalent atoms or groups in which two atoms on same carbon are different, there will be 2 isomers, one cis and one trans.
Case 2:
When a molecule has one carbon-carbon double bond and four monovalent atoms or groups where both atoms attached to the same carbon are same, there will be no geometrical isomerism.
As based on priority, there will be only two orientations possible , in which same priority atoms are on the same side that is cis and if they are on the opposite side that is trans.
The one from the cupboard because it is warmer (has more thermal energy) than the one from the refrigerator. When a liquid becomes warmer, the solubility of a gas becomes lower. Therefore, there is already more CO2 in its gaseous state when the soda is warm.
