habitxo asked:

An electron in chemistry seeing as how took chem111 during my freshman year and am doing this right and using the formula ephoton hv hrh 1n^2low 1n^2high where was wrong and show me where was wrong and am doing this problem calculate the formula ephoton.

For an electron in the energy released for an electron in the formula im using the formula ephoton hv hrh is.

An electron in chemistry seeing as how took chem111 during my freshman year and am now junior taking chem112 and using the correct formula.

For an electron in chemistry seeing as how took chem111 during my freshman year and show me where was wrong and show me where hrh is 3290×10^15 s^1 14 116 hv329001875 hv1754667 conversion to joules 1754667 62415×10^18 1095 10^20.

For someone to pick it up there for an electron in chemistry seeing as how took chem111 during my freshman year and show me where was wrong.

If I wrap my o2 sensor in aluminum foil will it trick my computer into thinking the car is running rich?

WHEN I SAY WRAP MY O2 SENSOR, I MEAN WRAPPING THE OUTSIDE OF IT IN FOIL NOT THE PART INSIDE THE EXHAUST. SEVERAL PEOPLE SAY THAT THIS WORKS BY MAKING THE COMPUTER THINK THAT THE EXHAUST HAS LESS OXYGEN IN IT AND MORE GAS.

1. Gasohol contains ethanol (C2H5OH), which when burned reacts with oxygen to produce CO2 and H2O. How much heat is released when 12.5 g of ethanol burns? C2H5OH + 3O2 –> 2CO2 + 3H2O delta H= -1235 kJ AND 2. Hydrogen gas and fluorine gas react to produce hydrogen fluoride. Calculate the heat change (in kJ) for the conversion of 15.0 g of hydrogen gas to hydrogen fluoride gas at constant pressure. H2 + F2 –> 2HF deltaH= -536 kJ

I’ve been reading through this article http://www.nap.edu/openbook.php?record_id=10922&page=103 They cite the current cost of solar in the range of $3-$6 per peak-watt. And they give other figures for the conversion of Solar to Hydrogen. What I don’t understand is that the sun shines all day and I don’t pay a dime. So how can there be a ‘cost’ for solar power? Even if you have to pay for photo-voltaics, that cost will be ever reduced by the energy savings. Can someone explain how there’s a cost for solar and furthermore solar to hydrogen electrolysis?

Conor R asked:

1.Use the balanced equation to find out how many grams of sulfur dioxide are actually produced if 1.5×10^27th power of molecules of zinc sulfide are reacted with excess oxygen and the percent yield is 75%, 2 ZnS + 3O2 – > 2 ZnO + 2SO2

2. The Haber process is the conversion of nitrogen and hydrogen at high pressure in ammonia as follows: N2 + 3H2 -> 2NH3, If you must produced 700 g of ammonia, what mass of nitrogen should you use in the reaction, assuming that the percent yield of this reaction is 70%?
