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 %

Answer:
Option A= copper
Explanation:
According to specific heat capacity of substances, copper will reach to the our body temperature first.
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m × c × ΔT
specific heat capacity of copper = 0.385 J/g. °C
specific heat capacity of aluminium = 0.902 J/g. °C
so copper will absorb the heat very quickly and raise the temperature in very less time as compare to aluminium.
Answer:
1.930 * 10⁻⁹ mg of Mn⁺² are left unprecipitated.
Explanation:
The reaction that takes place is:
Mn⁺² + S⁻² ⇄ MnS(s)
ksp = [Mn⁺²] [S⁻²]
If the pksp of MnS is 13.500, then the ksp is:
From the problem we know that [S⁻²] = 0.0900 M
We use the ksp to calculate [Mn⁺²]:
3.1623*10⁻¹⁴= [Mn⁺²] * 0.0900 M
[Mn⁺²] = 3.514 * 10⁻¹³ M.
Now we can calculate the mass of Mn⁺², using the volume, concentration and atomic weight. Thus the mass of Mn⁺² left unprecipitated is:
3.514 * 10⁻¹³ M * 0.1 L * 54.94 g/mol = 1.930 * 10⁻¹² g = 1.930 * 10⁻⁹ mg.
