Answer:
The number of Chlorine atoms in the product is 2.
Explanation:
The law of conservation of mass states that matter can neither be created nor destroyed in a chemical reaction.
The reactants contain one chlorine molecule() which has two chlorine atoms.
Then, according to law of conservation of matter, the product must contain two chlorine atoms.
Answer:
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.
Explanation:
Average rate of the reaction =
=Average rate of the reaction during the given time interval.
= Change in concentration of reactant with respect to time.
= Change in time.
=Concentration of reactant at time
=Concentration of reactant at time
So, at the concentration of :
And at the concentration of :
The average rate of the reaction at given interval will be given as:
0.001341 mol/L s is the average rate from 8.0 to 20.0 seconds.
The color change would only effect the appearance of the substance, so it would be a physical change.
Answer: physical change
