If there are 10 navy beans,3 pinto beans,and 17 lentils in a container,what is the percent composition of the container by bean?
Stells [14]

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 %

Which of these elements has an atom with the most stable outer electron configuration? * Cl Ca Ne Na
SashulF [63]

Answer:

Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure

Explanation:

The configuration of these elements is as follows;

Cl₁₇ = 2, 8,7 (the outer electron is 7)

Ca₂₀ = 2,8,8,2 (the outer electron is 2)

Ne₁₀ = 2,8 (the outer electron is 8)

Na₁₁ = 2,8,1 (the outer electron is 1)

Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.
