so washington has been hit really bad with wind/rain storms. power was out for over a million houses today and they dont expect to be able to get it all fixed for at least a couple days.there's also trees fallen on houses, i believe a couple people have died. grocery stores have lost all of their perishable foods, etc. there's a LOT of damage. is any of the rest of the west coast -or anywhere in the us for that matter- having storms like these? or is it just us up here?... just curious

1. A hyrocarbon sample with a mass of 6 grams underwent combustion, producing 11 grams of carbon dioxide. If all of the carbon initally present in the compound was converted to carbon dioxide, what was the percent of carbon, by mass, in the hydrocarbon sample.

2. A sample of propane was completely burned in air at STP. The reaction occured as shown below
C3H8 + O2 --------> 3CO2 + 4H20
If 67.2 liters of CO2 were produced and all of the carbon in the CO2 came from the propane, what was the mass of the propane sample?

3. The concentration of sodium chloride in sea water is about 0.5 molar. How many grams of NaCl are present in 1kg of sea water?

4. What is the STP volume of SO2 gas produced when 145 grams of ZnSO3 are consumed?
ZnSo3(s) -----> ZnO(s) + SO2

how come people get bigger then each other? is it the diet of their particular breed? can you take a smaller breed, isolate them, feed them more and make them a bigger breed or is it all just family genetics? how come say like Polynesians are bigger then regular asain people, I see some Tongans and Samoans that look similiar to me, but a lot bigger?

Are they jumping to conclusions about this?
It could be anything (a smudge, even) but if this true, then what kind of life, I wonder, once existed there.
And could there be life again?
