Write the reaction rate expressions for the reaction below in terms of the disappearance of the reactants and the appearance of products. give the expressions for the disappearance of the reactants first, in the order written in the chemical equation. then write the expressions for the appearance of the products in the order written in the chemical equation. write the expressions in order of appearance in the equation in the form. ± 1 x × δ[α] δt where ± is either a plus or a minus sign, not both, x is an integer, and a is a chemical species. do not include the state of matter. 2h2(g) + o2(g) → 2h2o(g)

idk

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
