He used prisms to demonstrate how white light is in fact made
<u>Answer:</u> The concentration of hydrogen gas at equilibrium is 0.037 M
<u>Explanation:</u>
We are given:
Initial concentration of HI = 1.0 M
The given chemical equation follows:
<u>Initial:</u> 1.0
<u>At eqllm:</u> 1.0-2x x x
The expression of 
for above equation follows:
![K_c=\frac{[H_2][I_2]}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5BI_2%5D%7D%7B%5BHI%5D%5E2%7D)
We are given:
Putting values in above expression, we get:
Neglecting the negative value of 'x' because concentration cannot be negative
So, equilibrium concentration of hydrogen gas = x = 0.037 M
Hence, the concentration of hydrogen gas at equilibrium is 0.037 M
Answer:
Ki = 30atmL
Kf = 30atmL
Explanation:
The following data were obtained from the question:
V1 (initial volume) = 15.0L
P1 (initial pressure) = 2atm
V2 (final volume) = 7.5L
P2 (final pressure) = 4atm
Ki (initial constant) =?
Kf (final constant) =?
Boyle's law states that PV = K
Ki = P1V1
Ki = 2 x 15 = 30atmL
Kf = P2V2
Kf = 4 x 7.5 = 30atmL
Since Ki and Kf are the same, the gas obey Boyle's law
Answer:
a risk to human health or the environment arising from biological work, especially with microorganisms.
Explanation:
The reaction above is a spontaneous reaction
Cu^2+ + 2Br^- --> Cu + Br2
<h3>What is spontaneous redox reaction?</h3>
A spontaneous redox reaction is a special type of redox reaction which involves the release of energy where the electrons are transferred from from an anode to the cathode
General spontaneous redox reactions is found mostly in electrochemical cells
So therefore, the reaction above is a spontaneous reaction.
Cu^2+ + 2Br^- --> Cu + Br2
