Answer : The partial pressure of 
and 
is, 216.5 mmHg and 649.5 mmHg
Explanation :
According to the Dalton's Law, the partial pressure exerted by component 'i' in a gas mixture is equal to the product of the mole fraction of the component and the total pressure.
Formula used :
So,
where,
= partial pressure of gas
= mole fraction of gas
= total pressure of gas
= moles of gas
= total moles of gas
The balanced decomposition of ammonia reaction will be:
Now we have to determine the partial pressure of and
Given:
and,
Given:
Thus, the partial pressure of and is, 216.5 mmHg and 649.5 mmHg
PH=-log[H⁺]
pH=-log(1.87×10⁻¹³)
pH=12.72
I hope this helps. Let me know if anything is unclear.
Explanation:
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
When interaction between the solute and solvent are weak then solution will evaporate readily into the atmosphere. Therefore, it means vapor pressure increases with particularly weak solute-solvent interactions.
On the other hand, when interactions between the solute and solvent of a strong enough in a solution then vapors are not formed easily. This also means that vapor pressure decreases with particularly strong solute-solvent interactions.
Answer:
E°red for Tl³⁺(aq) | Tl⁺(aq) is 0.78 V
Explanation:
According to cell reaction we can predict which one cathode half cell and which one anode.
We know left hand side electrode where oxidation occur acts as an anode and right hand side electrode where reduction take place acts as an cathode.
Hence Cr²⁺ converted into Cr³⁺ since oxidation is take place where as Ti³⁺ converted into Ti⁺ means reduction take place.
<u>Anode half cell </u>is Cr³⁺(aq) | Cr²⁺(aq) is E⁰red = -0.41 V
<u>Cathode half cell</u> is Ti³⁺(aq) | Ti⁺(aq) is E⁰red = ?
E⁰cell = E⁰cathode - E⁰anode
⇒ E⁰cathode = E⁰cell + E⁰anode
⇒ E⁰cathode = 1.19 + (- 0.41) volt = 0.78 V
Answer:
hope it helps...
Explanation:
The greenhouse effect is caused by the atmospheric accumulation of gases such as carbon dioxide and methane, which contain some of the heat emitted from Earth's surface. The atmosphere allows most of the visible light from the Sun to pass through and reach Earth's surface.
