Answer : The rate constant at 525 K is,
Explanation :
According to the Arrhenius equation,
or,
where,
= rate constant at =
= rate constant at = ?
= activation energy for the reaction =
R = gas constant = 8.314 J/mole.K
= initial temperature = 701 K
= final temperature = 525 K
Now put all the given values in this formula, we get:
Therefore, the rate constant at 525 K is,
Answer: 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
Explanation:
To calculate the moles, we use the equation:
The decomposition of ammonium perchlorate is :
According to stoichiometry :
2 moles of produce = 1 mole of
Thus 0.028 moles of produce= of
Mass of
Thus 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
Answer:
higher costs, energy use and carbon emissions
Explanation:
not sure if this is right or not, I apologize if this is wrong
100.0ml*0.400m =xml *2.00m
x=100.0*0.400/2.00= 20 ml 2.0 m CaCl2
you need to take 20 ml 2.0 m CaCl2 and dilute it with water up to 100.0 ml
