Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,

In a way, all of the answers could be argued for (for example: in the first option: if the scientists' opinions are understood to be "informed understanding of the causes of events"), but one of the options is the best:
Scientific laws describe specific relationships in nature without offering
an explanation.
The reason why I think this is true is that many laws are phased too short and too concise to provide comprehensive explanations, instead they describe the relationships that must hold.
One of the options is pplain false:
Scientific laws explain why natural events occur. -"Scientific laws were theories that have been tested, proven, and adopted as laws." - since they are not adopted as laws.
Answer:
Sry i am unable to see the attached picture but i hope this helps
Explanation:
There are a couple of ways to prepare a buffer solution of a specific pH. In the first method, prepare a solution with an acid and its conjugate base by dissolving the acid form of the buffer in about 60% of the volume of water required to obtain the final solution volume
Chlorine-35 and 37 both have the same number of protons. Chlorine-37 has two more neutrons.
hope this helps!

The student originally has 252 grams of water in this experiment.
LAW OF CONSERVATION OF MASS:
- The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another.
- This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s).
- According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen.
- Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water.
- Therefore, 224g of oxygen + 28g of hydrogen = 252g of water.
