Answer:
Water is most dense as a liquid, then as a solid, and least dense as a gas. Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.
Explanation:
Answer: The atomic mass of these two isotopes is 40.03 amu. The average mass is closer to actual amu of 58.69 for nickel as its percentage abundance is more.
Explanation:
Mass of isotope 1 = 63.93
% abundance of isotope 1 = 0.93% =
Mass of isotope 2 = 57.93
% abundance of isotope 2 = (68.08)% =
Formula used for average atomic mass of an element :
Therefore, the average atomic mass of nickel is, 40.03 amu. The average mass is closer to actual amu of 58.69 for nickel as its percentage abundance is more.

d answer is correct that help
Answer:
1. 11g
2. 909
Explanation:
To get the Weight of a 109 washers who weigh 0.110g each we have to find the ratio of Weight of one washer to 1 washer and multiply by 100
= 100 washers x 0.110g/1 washer
= 11g
Therefore the mass of 100 washers is 11 grams
2.
Then the number of washers =
100g x 1washer/0.110g
= 909
Therefore number of washers = 909
