Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.
Answer:
A relationship is a person and their partner commited to each other romantically.
I have completed the problem
Answer:
Explanation:
To slow down this reaction, we can use any of the methods listed below:
- Increase the size of the magnesium by using solid lumps of the metal. This will take a much faster time to react than powered and granulated magnesium.
- Reduce the concentration of the acid.
- Let the reaction take place at a much lower temperature than that given.
These conditions will slow down a chemical reaction.
According to the PH formula:
PH= Pka +㏒ [strong base/weak acid]
when we have PH at the first equivalence =3.35 and the Pka1 = 1.4
So, by substitution, we can get the value of ㏒[strong base / weak acid]
3.35 = 1.4 + ㏒[strong base/ weak acid]
∴㏒[strong base/weak acid] = 3.35-1.4 = 1.95
to get the Pka2 we will substitute with the value of ㏒[strong base/ weak acid] and the value of PH of the second equivalence point
∴Pk2 = PH2 - ㏒[strong base/ weak acid]
= 7.55 - 1.95 = 5.6
