Answer:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp
Explanation:
The reaction is:
2NO + 2H₂ → N₂ + 2H₂O
The expression for Kp (pressure equilibrium constant) would be:
Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²
There is another expression for Kp, where you work with Kc (equilibrium constant)
Kp = Kc (R.T)^Δn
where R is the Ideal Gases constant
T° is absolute temperature
Δn = moles of gases formed - moles of gases, I had initially
It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 molecule contains 6.022×10^23 elementary entities of the substance.
Hope that helps
Answer:
Temperature is not a chemical change because when a substance changes in temperature, its chemical makeup is not changing.

Answer:
17.2mL are needed
Explanation:
<em>The pH curve for titration of 50.0 mL of a 0.100 M solution of hydrochloric acid</em>
<em />
A strong acid as HCl reacts with a strong base as NaOH producing water and a salt. The chemical equation is:
HCl + NaOH → H₂O + NaCl
<em>Where 1 mole of HCl reacts per mole of NaOH</em>
<em />
To solve this question we must find the moles of HCl added = Moles NaOH you must add to reach the equivalence point. With these moles and the molar concentration we can find the volume that would be needed as follows:
<em>Moles HCl:</em>
50.0mL = 0.0500L * (0.100moles / L) = 0.00500 moles HCl = Moles NaOH
<em>Volume NaOH:</em>
0.00500 moles NaOH * (1L / 0.290moles) = 0.0172L NaOH =
<h3>17.2mL are needed</h3>
