Then why am I calculating the moles if I just need to look up the Change in H for products and reactants...that isn't going to give me the heat released. What formulas do I need to use?
what is the rate of reaction, if rate of consumption of iodide is 2.130x10^-5? 5I-(aq)+IO3-(aq)+6H+(aq)<-> 3I2(aq)+3H2O(l)
the half life of F18 is 2.089x10^-4yrs. How long would it take (in days) for F18 to decrease to 78.71% of its initial amount?

Ksp = [Ra^+2][SO4^-2] 4.3x10^-11 = [x][x] x=6.56x10^-6 6.56x10^-6 + .1381?? is that how im suppose to do it?

a 15 year bond pays 11% on a face value of $1000. If similar bonds are currently yeilding 8%, what is the market value of the bond? use annual analysis
a 10 year bond pays 8% on a face value of $1000. If similar bonds are yeilding 10%, what is the market value of the bond. use annual analysis
the longer the time to maturity: the greater the price increase from an increase in interst rates; the less the price increase from an increase in interest rates; the greater price increase from a decrease in interest rates; the less the price decrease fron a decrease in ...

My Hypothesis was the I beleive leaves change color due to photosynthisis.
am having trouble with Restate the problem in terms of the following: Manipulated variable Constant (control) variables Principles of experimental design State in correct form the hypothesis you intend to demonstrate. I have conducted the experiment but I am not sure how to ...
the experiment was How do leaves change color? I collected 2 large leaves from a maple and acorn tree. I chopped the leaves into very small pieces and put them into small jars labeled with the name or location of the tree. I added rubbing alcohol to each jar to cover the ...
