Answer:
Cl^-<NO3^-<H2O<F^-<CN^-
Explanation:
When we talk about base strength we are referring to how easily a chemical specie accepts protons.
The greater the ability of a specie to accept H^+, the greater its base strength.
The order of increasing base strengths of the species listed are shown in the answer above.
Answer:
Acetic acid , systematically named ethanoic acid , is a colourless liquid organic compound with the chemical formula CH3COOH.
Explanation:
Answer:
15.04 mL
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 21 L
V₂ = ?
P₁ = 9 atm
P₂ = 15 atm
T₁ = 253 K
T₂ = 302 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 15.04 mL</u>
