Doing the calculations on part F from the attached assignment.
How many oxygen atoms are there in a simple carbohydrate
A single pulse of a laser yields an average of 5.00 multiplied by 1018 photons with = 633 nm. If melting ice to water at 0 C requires 6.01 kJ/mol, what is the fewest number of laser pulses need to melt 10.0 g of ice?
If 29mL of 6.4 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
calculate the volume of a 1.420 m NaOH solution required to titrate 33.55 ml of a 1.500m H3PO4 solution
How many moles of PCl5 are in 35.6 g of PCl5?
a sample of N2O3(g) has a pressure of 0.019atm. the temperature(in K) is then double and the N2O3 undergoes complete decompositopn to NO2(g) and NO(g). what is the total pressure of the gases
HCLO3 is a colorless, corrosive liquid. At 25 C its density is 4.63 g/mL. A chemist needs 125. g of this acid for a reaction, but often it is safer and more convenient to measure reactive liquids by volume with a graduated cylinder instead of attempting to weigh them on a balance. Calculate the...

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
- 1. For organic chemistry, what is a concerted shift? How do things like acids or heat affect them? What other factors affect them?
2. Which of the following reactions is an acid-base neutralization reaction? Why are the rest of the answers incorrect?
- A. AgNo3 (aq) + NaI (aq) --> AgI (s) + NaNO3 (aq)
- B. S8(s) + 8O2 (g) --> 8SO2(g)
- C. Na3PO4 (s) + 2H2O (l) --> H2 (g) + 2NaOH (aq)
- D. Ca (OH)2 (aq) + 2HI (aq) --> CaI2(aq) + 2H2O (l)
