The percent abundance in the container by bean will be 43.33 % if there are 10 navy beans, 3 pinto beans, and 17 lentils in a container
<h3>What is Percentage composition ?</h3>
The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100.
% composition by bean = number of beans / total number of objects in container x 100
- Total object = 10 ( navy beans) + 3 (pinto beans) + 17 ( lentils) = 30 objects
- Total beans = 10 ( navy beans) + 3 (pinto beans) = 13 beans
hence ;
- % composition by beans = 13/30 x 100 = 43.33 %
Therefore, the percent composition of the container by bean is 43.33 %

Explanation:
Find the mass of one atom by:
8.33 x 10^{-16} / 2.5 x 10^{6} = 3.32 x 10^{-22} g
Convert it into amu.
1 g = 6.022 x 10^{23} amu
so, 3.32 x 10^{-22} x 6.022 x 10^{23} = 200.6 amu
Now look at the periodic table and search for 200.6 amu element.
The element is Mercury (Hg)
It is better for the whales to go where the whales have the ability to dive longer and deeper to find cooler water.
Explanation:
It is known that molecular formula of potassium dichromate is 
. As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.
Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.
= 0 (as the molecule is neutral)
= 0
2 + 2x - 14 = 0
x = +6
Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
