Answer:
(1) Rate = k[NO2]^2[CO]
(2) The rate of the reaction is 1.195 Ms^-1
Explanation:
(1) Equation of reaction
NO2 + CO = NO + CO2
The reaction is second-order in NO2 and zero-order in CO
Therefore, rate = k[NO2]^2[CO]^0
(2) Rate = k[NO2]^2[CO]^0
k = 0.790 M^-1s^-1
[NO2] = 1.23 M
[CO] = 0.221 M
Rate = 0.79×1.23^2×0.221^0 = 1.195 Ms^-1
It absorbs the quants of energy the photon was carrying and moves higher
Answer:
The required volume of the original sample required is 2 micro liter
Explanation:
assuming the original sample concentration is 1N
after final dilution of 10-2 solution concentration becomes 0.01 N
normality of original sample = 1 N
normality of final solution = 0.01 N
volume of original sample= ?
volume of final solution = 0.2 mL
Considering thef formula below :
N1V1 = N2V2
V1 = (N2V2)/N1
= (0.01*0.2)/1
= 0.002 mL
1 milli liter = 1000 micro liter
0.002 mL = 2 micro liter
The original sample required is 2 micro liter
No it can't. To be a molecular compound it should <span>contains at least two different elements. As it is made up of only gold (Au) atoms it violates the above requirement.</span>
Answer:
Communicating Results
This is a very important step because it allows other scientists to try to repeat the investigation and see if they can produce the same results. When scientists communicate their results, they should describe their methods and point out any possible problems with the investigation.
