Answer:
None
Explanation:
Isomers are organic compounds that have the same molecular formula but different structural formula. What this mean is that these isomers have different arrangement of their atoms. Hence, they belong to different homologous series and exhibit different chemical properties. Hence, it is enough to access whether two different compounds are isomeric using their chemical formula as a yardstick.
Now let us look at our answers. We can see that none of the pairs have the same molecular formula
There are 2.2 moles in 35.7 g of CH4! To find this, you have to divide 35.7 by the molar mass of CH4, which is 16.0!
Answer:
Lets Write Down the Given Initial Conditions.
In Order to Solve for the Unknown:
we must use the Ideal Gas Law to Solve for the Second Unknown pressure:
Then Rearrange this equation in a form where P2 can be solved from:
Then Insert the Values from above to solve:
The Answer is : 1830 mmHg considering sig figs
Answer:
We need to add 900 mL of water.
Explanation:
To know the amount of water to add first we need to calculate the concentration of KOH when the pH is 12 and when is 11:
When pH = 12 (initial):
When pH = 11 (final):
Now, by using the following equation we can find the volume of the solution to achieve a pH = 11:
Finally, to bring 100 mL of the initial solution to 1000 mL we need to add the following amount of water:
Therefore, we need to add 900 mL of water.
I hope it helps you!
