Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,
Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.
Substitute the values then we get
Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
4/x=1/3 Cross multiply.
X=12 12 bracelets.
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
<u>Dana : she works 4 days and gets paid $ 12.75 per dog...and she grooms 15 dogs per day.....so Dana makes : 4(12.75 * 15) = 4(191.25) = $ 765</u>
<u>Monique : she works 5 days and gets paid $ 12.75 per dog...and she grooms 10 dogs per day....so she makes : 5(12.75 * 10) = 5(127.50) =</u>
<u>$ 637.50</u>
<u>so the difference between their weekly earnings is : (765 - 637.50) =</u>
<u>$ 127.50 </u>
