Answer:
1.15 atm
Explanation:
According to Dalton's law of partial pressures, the total pressure is the sum of all the partial pressures of the gases present in the mixture.
Therefore we have:
Total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide
We were given the following:
Total pressure = 2.45 atm
Pressure of oxygen = 0.65 atm
Pressure of carbon monoxide = x
Pressure of carbon dioxide = 0.65 atm
Therefore:
2.45 = x + 0.65 + 0.65
2.45 = x + 1.3
x = 2.45 - 1.3
x = 1.15 atm
I think that it is true to the bone
(A) Al(OH)₃ > Mg(OH)₂ > NaOH
polarity is increasing as the metallic character is increasing . So this order is not correct. NaOH as we all know is completely soluble in water.
(B) BaSO₄> CaSO₄ > MgSO₄
This one is also not correct because here also polarity is increasing so solubility should increase.
(C) CaCO₃> NaHCO₃ > Na₂CO₃
this is als not correct .Na₂CO₃ is more polar is completely soluble in water whereas CaCO₃ is insoluble.
(D) AgCl > AgBr > AgI
In D as we go from AgCl to AgI polarity is decreasing so solubility is decreasing .
Answer:
Explanation:
In this case, we have to start with the <u>reagents</u>:
The compounds given by the problem are:
-) <u>Nitrogen gas</u> =
-) <u>Water vapor</u> =
-) <u>Aluminum oxide</u> =
Now, we can put the products in the <u>reaction</u>:
When we <u>balance</u> the reaction we will obtain:
Now, for the enthalpy change, we have to find the <u>standard enthalpy values</u>:
With this in mind, if we <u>multiply</u> the number of moles (in the balanced reaction) by the standard enthalpy value, we can calculate the energy of the <u>reagents</u>:
And the <u>products</u>:
Finally, for the total enthalpy we have to <u>subtract</u> products by reagents :
I hope it helps!
