Answer:
Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo a chemical transformation or physical transport.
Answer:
2.5 mL of 1.0 x 10⁻⁴ M solution needs to be added
Explanation:
M₁ (Molarity after dilution) = 1.0 x 10⁻⁵ M
V₁ (volume after dilution) = 25.0 mL
M₂ (molarity before dilution) = 1.0 x 10⁻⁴ M
dilution equation is written as M₁V₁ = M₂V₂
Making V₂ the subject of formula
V₂ = M₁V₁ / M₂
Substitute the parameters in the equation,
V₂ = 1.0 x 10⁻⁵ x 25.0 / 1.0 x 10⁻⁴
= 2.5 mL
Volume of the solution before dilution is 2.5 mL
Repeat same step for the next
207 and the name of atom is Lead (Pb)
Trả lời:3 5-dimethylheptane
Explanation:
The +1 is a charge, but really + means minus, and - means addition.
