You have studied the gas-phase oxidation of hbr by o2:
4hbr(g)+o2(g)→2h2o(g)+2br2(g)
you find the reaction to be first order with respect to hbr and first order with respect to o2. you propose the following mechanism:
hbr(g)+o2(g)→hoobr(g)
hoobr(g)+hbr(g)→2hobr(g)
hobr(g)+hbr(g)→h2o(g)+br2(g)
based on the rate law, which step is rate determining?

Asa choose the correct set of reaction coefficients to properly balance the following chemical equation according to the law of conservation of mass: __s8 + __o2 ==> __so2 1, 1, 8 1, 8, 1 1, 8, 8 8, 1, 1

Why does the sun appear to be the brightest star in the sky? a- its apparent brightness is much greater than other stars. b- it burns more gas, making it brighter than any other star. c- it is the largest star in the galaxy, so it is the brightest star. d- its relative distance to earth is closer than the other stars.
