<u>Given:</u>
Volume of gas = 215 ml
Initial temperature T1 = 20C = 20 +273 = 293 K
Initial pressure P1 = 1 atm
Final pressure P2 = 1.5 atm
<u>To determine:</u>
The final temperature T2
<u>Explanation:</u>
Based on Gay-Lussac's Law:
P α T
Therefore we have the relation:
P1/T1 = P2/T2
T2 = P2T1/P1 = 1.5 *293/1 = 439.5 K
Converting from Kelvin to degrees C we have:
T2 = 439.5 - 273 = 166.5 C
Ans: The final temperature is 439.5 K or 166.5 C
An Arrhenius base is a substance that are being dissolves in water dissociate and gives Hydroxide ions. (OH⁻)
Answer:
Dalton's says atoms of different elements differ in size and mass, whereas the modern theory says they differ in average mass. Dalton's says atoms are individual particles, whereas the modern theory says atoms are divisible into subatomic particles like protons, neutrons, and electrons..

Answer:
The higher the hydronium ion concentration of a solution, the <u>lowe</u>r its pH.
Explanation:
Consider a <em>high</em> hydronium concentration, 1 mol·L⁻¹.
pH = -log[H₃O⁺] = -log1 = 0
Now consider a <em>low</em> hydronium ion concentration, 10⁻¹⁴ mol·L⁻¹.
pH = -log(10⁻¹⁴) = 14
Thus, a <em>high</em> hydronium ion concentration means a <em>low </em>pH.
