At 1:00 p.m., a car leaves a city and travels north at a rate of 55 mi/h. An hour later, a second car leaves the city and travels south at a rate of 60 mi/hr. At what time will the two cars be 285 miles apart?

My husband saw a crow doing some very unusual things. As the crow flew he would do barrel rows. He did this twice and was also cawing up a storm. Has anyone else seen this?

On the subject of Gluons, Color is a conserved quantity. Also, there are 9 possible combinations of Color-Anticolor Charge. There should then be 9 different Gluon charges, but there are only 8. How is this possible?

The atomic # is the number of protons and usually, the electrons are the same as the protons. Does this apply with isotopes where the neutrons are the only ones that change?

I'm talking about a vacuum, like the science term, not the thing you clean your floors with. I know you techincally probably can't breathe in a vacuum, but for now just assume that breathing isn't a problem.

I assume I'd have to write to some government organization if I wanted information on schematics and floor plans of old, retired bases. Does anyone here know who exactly I'd write? I'd guess DoD, but I don't know if it should be someone like NORAD instead.

NO + NO => N2O2 [fast]
N2O2 + H2 => N2O + H2O [slow]
N2O + H2 => N2 + H2O [fast]
From the mechanism above, a student deduces that the rate law of the reaction is rate = k[NO]^2[H2]. The student concludes that [1] the reaction is third order and [2] the mechanism involves the simultaneous collision of two NO molecules and an H2 molecule. Are the conclusions in [1] and [2] correct?

I thought it was no but i don't think i did it right. I found the equation to be [after intermediates were taken out]: NO + NO + H2 + H2 => H2O + N2 + H2O [and it's already balanced]
i looked back at my notes, but the way my teacher did it was confusing and they were easier ones too.
is there an easier and less confusing way to do reaction mechanisms?
