Hi
i need which expression is equivalent to 8x-2y+x+x?

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

Teams of 4 are competing in a 1/4 mile relay race. each runner must run the same exact distance. what is the distance each teammate runs?
