Answer:
Concentration solution A was 0.5225 M
Explanation:
10.00 mL of solution A was diluted to 50.00 mL and yields 50.00 mL of solution B
According to laws of dilution- 
where, 
and 
are concentration of solution A and B respectively
and 
are volumes of solution A and B respectively
Here = 0.1045 M, = 50.00 mL and = 10.00 mL
Hence, 
So, concentration solution A was 0.5225 M
Answer: There are four atoms
Explanation: mass of Cl atom is 35.45 amu
Amount of atoms n = m/M = 142 / 35.45 = 4
I recently did this assignment!
Instructions: Read each myth (untruth). Reword it to make a factual statement. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with evidence, using your own words.

Answer:
Myth: A dead organism is the same as a nonliving thing in science.
o Fact: In science, dead is the same as nonliving.
o Evidence: Things that are nonliving never had the characteristics of life, and never will. Things that are dead once did have the characteristics of life, but when they die, they lose some of the characteristics. That is why dead and non-living are NOT the same thing.
Hope this helped!
