You want to put $4,000 in a simple interest account. It has a 2.5% annual interest rate. How long will it take you to earn $500 in interest?
How do you add fractions??
What would be the final temperature when 125g of 25 degrees Celcius water is mixed with 85g of 45 Degrees Celcius water? ( hint: Equate the heat gained by the cool water with the heat lost by the warm water.)
How do you find the total number of maximum and minimum points of the function whose derivative is given by f^1(x)=x(x-3)^2(x+1)^4 ???
Calculate the pH at the equivalence point when 50 mL of 0.098 M propionic acid is titrated with 0.340 M NaOH. I tried solving for the volume of NaOH and them using the total volume and then plugging it in to [H+][A-]/[HA] and used the Ka value for propionic acid but it was not...
Calculate the pH of a buffer solution that contains 0.60 M NaH2PO4, and 0.26 M Na2HPO4.
The pH of an 0.0870 M solution of weak acid A is 2.20. The pH of an 0.0830 M solution of weak acid B is 4.07. The pH of an 0.0890 M solution of weak acid C is 5.13. Identify the three acids from among those listed below (the Ka values are listed in Appendix E of your textbook)...
I'm not really sure how to go about doing this problem... What is the pH of a 7.40 x 10-3 M solution of NH4Cl? Help is appreciated! Thank you
write and inequality describing this region. will an 18 wheeler hold 71 refrig's and 118 tv's or will it hold 51 refig's and 176 tv's?
Awesome! Thank you
