a random question i found on a game.

2007-12-23 10:46:10 · 21 answers · asked by Anonymous in Other - Science

I ask because i myself believe it is much older than scientists would have us believe. I base my belief on this. scientists say it is about 15-20 billions years old based on the fact that that is how long it has taken light to reach us from the farthest reaches that telescopes of any kind have been able to see. But if that is true then how about the time it took for the objects that are out that far whose light the telescopes are seeing took to get where they are at vastly slower speeds than their light we see takes getting back to our telescopes. I hope I have explained myself so that someone understands what it is I am trying to say

At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8935 g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over water occupied 57.2 mL at a temperature of 22°C and a pressure of 746 torr. Calculate the mass percent of NaClO3 in the original sample. (At 22°C the vapor pressure of water is 19.8 torr.)



Please explain tooo. THANKS ! :D
