Answer: Skier 1 will have more potential energy because he is higher than skier 2
Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.
P.E=
m= mass of the body
g= acceleration due to gravity
h= height of body
Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
Answer:
less HCL acid is required to neutralize a weaker solution of base (sodium bicarbonate).
Explanation:
PV = nRT, or (pressure)(volume) = (amount of gas)(universal gas constant)(temperature)
<span>You're solving for pressure, so start by rearranging the equation: </span>
<span>p = (nRT)/V </span>
<span>You're given temperature; all you need to do is convert it to Kelvin. (The universal gas constant is 8.31 J/(Kmol), so the units for temperature need to be the same.) </span>
<span>But how to figure out the rest? The question doesn't give you the size of the flask or number of moles, but it does tell you that these things don't change throughout the problem. Because they're constant, we don't have to know exactly what they are - we just have to know the *combined values* of the constants. (If this is confusing, think about it this way: a small amount of gas in a small flask will exert the same amount of pressure as a large amount of gas in a large flask, as long as the ratios are kept equal - it doesn't matter if it's 2 moles in 2 L, or 1 mole in 1 L.) </span>
<span>To figure out this constant, go back to the opening, where you're given temperature and pressure. </span>
<span>pV = nRT </span>
<span>Remember to convert celsius to kelvin! </span>
<span>(254mm Hg)(V) = nR(330K) </span>
The rate determining step would be the slow step. Thus, Step 2 which is bimolecular is the rate determining step. I believe the correct answer from the choices listed above is option C. The reasonable conclusion would be that it <span> is second order overall because step 2 is bimolecular. Hope this answers the question.</span>
