STALIN [3.7K]3 years ago
7 0

Answer: Solution A : [H_3O^+]=0.300\times 10^{-7}M

Solution B : [OH^-]=0.107\times 10^{-5}M

Solution C : [OH^-]=0.177\times 10^{-10}M

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

pH=-\log[H_3O^+]

pOH=-log[OH^-}

pH+pOH=14

[H_3O^+][OH^-]=10^{-14}

a. Solution A: [OH^-]=3.33\times 10^{-7}M

[H_3O^+]=\frac{10^{-14}}{3.33\times 10^{-7}}=0.300\times 10^{-7}M

b. Solution B : [H_3O^+]=9.33\times 10^{-9}M

[OH^-]=\frac{10^{-14}}{9.33\times 10^{-9}}=0.107\times 10^{-5}M

c. Solution C : [H_3O^+]=5.65\times 10^{-4}M

[OH^-]=\frac{10^{-14}}{5.65\times 10^{-4}}=0.177\times 10^{-10}M

A 3.0 l container holds a sample of hydrogen gas at 300 k and 100 kpa. if the pressure increases to 400 kpa and the volume remai
Dahasolnce [82]
    The  temperature will  be  1200K   if  the volume remained   constant

      calculation
 This is calculated  using   gay lussac  law  formula,  that is P1/ T1=P2/T2  since the   volume is constant
P1 =  100 Kpa
T1=  300 K
P2=  400 Kpa
T2=?

by  making  T2   the subject of the formula  T2 =( P2 xT1)/P1

T2  is therefore = (400 KPa  x 300 K)  / 100 Kpa = 1200 K
