<span>
</span><span> average reaction rate </span><span>= change in concentration / change in time
by putting values we have
= (1.00M - 0.987M) / (4.00s - 0.00s)
= 3.25x10^-3 mol/Lsec
this is our conclusion
hope this helps</span>
Answer:
mostly gasoline in cars nowadays
384000000m
to change from m to km you just need to divide that give unit in Meters by 1000
which equals,
384000
so,
384000000 meters = 384000 kilometers
