The reaction in a young star is essentially: 4 11H --> 42He + 2 0+
How much energy (kJ/mol)would be produced per mole of He in this process?
To what volume should 32.00 mL of a 11.40 M HCl solution be diluted to prepare a 0.500 M HCl solution?
Assuming that di-lithium is very stable and the product of the fusion of two 6Li nuclei, the energy released per kilogram of di-lithium formed in the fusion process is closest to
What is the wavelength of an electron traveling with a velocity of 7.0 times 10 to the 3rd power?
the vapor pressure of Chlorine dioxide ClO2 is 155 torr at -22.75 degrees C and 458 torr at 0 degrees C. what is the normal boiling point of chlorine dioxide? use R=8.312 J/ K mol, answer in units of degrees Celsius.
Which material would have a larger mass 1.0Liter of ethanol or 1.0Liter of water?
The mean stoichiometric composition of fossil fuel burned is CH1.6 (1 part carbon for 1.6 parts hydrogen). We view fossil fuel combustion as a stoichiometric reaction where CH1.6 is oxidized by O2 to yield CO2 and H2O. Show that 1.4 moles of O2 are consumed per mole of CO2 emitted by fossil...

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)
