Answer:
Helium
Explanation:
Atomic radii vary in a predictable manner across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group and decreases from left to right over a period of time. Helium is therefore the smallest element, and francium is the largest.
Answer:
Final concentration = 10 M
Explanation:
Given data:
Initial volume = 100 mL
Initial molarity /concentration= 5 M
Final volume = 50 mL
Final molarity/concentration = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
Now we will put the values.
5 M × 100 mL = M₂ × 50 mL
500 M.mL = M₂ × 50 mL
M₂ = 500 M.mL / 50 mL
M₂ = 10 M
