2 ICl + H2 ----> I2 + 2 HCl
as given that rate is first order with respect to ICl and second order with respect to H2
The rate law will be
Rate = K [ICl] [ H2]^2
b) Given that K = 2.01 M^-2 s^-1
Concentrations are
[ICl] = 0.273 m and [H2] = 0.217 m
Therefore rate = 2.01 X (0.273)(0.217)^2 = 0.0258 M / s
Answer:
3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.
Explanation:
Answer:
Explanation:
The half life of a radioactive atom is the time taken for half of the radioactive nuclei to disintegrate. The shorter the half life, the faster a radioactive nuclei decays.
Half life is often expressed as:
Half life = 
Where λ is the decay constant.
Answer:
3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.
Explanation:
According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
The answer should be A, has more energy than it does in the ground state. De-excitation is removing electrons, so excitation would be adding more in to make it more stable. The ground state is what is considerd stable.
ANSWER: A
