Answer:

Answer: Amount of NOCl yielded increases

Explanation:

There is increase in volume following the forward reaction. When volume increases, there will be decrease in pressure for the forward reaction.

When pressure increases, backward reaction is favoured hence amount of NOCl produced increases whereas NO and Cl decreases.

⦁ Find the concentration of H+, OH-, PH and POH of 0.03 M of magnesium hydroxide which ionizes to the extent of only 1 /3 in aqu

lions [1.4K]

Answer:

$pH=12.3\\\\pOH=1.7\\$

$[H^+]=5x10^{-13}M$

$[OH^-]=0.02M$

Explanation:

Hello there!

In this case, according to the given ionization of magnesium hydroxide, it is possible for us to set up the following reaction:

$Mg(OH)_2(s)\rightleftharpoons Mg^{2+}(aq)+2OH^-(aq)$

Thus, since the ionization occurs at an extent of 1/3, we can set up the following relationship:

$\frac{1}{3} =\frac{x}{[Mg(OH)_2]}$

Thus, x for this problem is:

$x=\frac{[Mg(OH)_2]}{3}=\frac{0.03M}{3}\\\\x= 0.01M$

Now, according to an ICE table, we have that:

$[OH^-]=2x=2*0.01M=0.02M$

Therefore, we can calculate the H^+, pH and pOH now:

$[H^+]=\frac{1x10^{-14}}{0.02}=5x10^{-13}M$

$pH=-log(5x10^{-13})=12.3\\\\pOH=14-pH=14-12.3=1.7$

Best regards!

Which of the following statements is true?

Kazeer [188]

Only one: the nucleus of an atom is made up of protons and neutrons.
Why others are false:
Boiling point of a substance is not dependent on the volume because it’s a intensive property.
During sublimation, a solid changes directly into gas.
Electrons orbit the nucleus of an atom in circular orbits (kinda unsure of this one.)

It 32g of potassium nitrate can be dissolved in 1cm3 of water at 20oC before a saturated solution is obtained, how much potassiu

Dmitry_Shevchenko [17]

Answer:

160 gm

Explanation:

Five times as much water means you can dissolve 5 times as much potassium nitrate 5 x 32 = 160 gm <===== this seems unlikely though as I doubt 32 g of potassium nitrate will dissolve in only 1 cm^3 of water 1 cm^3 of water is only 1 gm of water
