Its A. because it measures the rate of the decay of the isotope
Answer:
V2 = 600ml
Explanation:
dilution principle formula
M1V1 = M2V2
C1V1 = C2V2
3 X 20 = 0.1 x V2
60 = 0.1 x V2
V2 = 60/0.1
V2 = 600ml

Answer : The correct option is A.
Explanation :
Enzyme-catalyzed reaction :
Enzyme act as a biological catalyst and the role of catalyst is to increase the rate of chemical reaction by lowering the activation energy.
Most of the chemical reactions are slow in the absence of enzyme but in the presence of enzyme, the reaction become faster. That means the Enzyme accelerate the rate of reaction.
Therefore, the correct answer is the reaction is faster than the same reaction in the absence of the enzyme.
The answer is 6.4109 grams
I believe the correct answer from the choices listed above is the third option. The <span>oxidation number of Nitrogen in HNO2 would be +3. It is calculated as follows:
1 + x + (-2)(2) = 0
x = +3
Hope this answers the question. Have a nice day.</span>
