Areaction require 1 mole of a gas at stp. you have 45.0l of a gas at 100kpa and 373k. which of the following statements is true? use the formula: pv=nrt where the gas is constant is 8.31 kpa/mol-k a) you will have an excess of gas and the reaction will occur. b) you do not have enough gas for the reaction to occur. c) you cannot tell this given information. d) you will have too much gas and so the reaction will not occur.

Hey There!

Here is your

Your answer is D. "You will have too much gas and so the reaction will not occur"

Hope this helps!

Iwould google this

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
