I believe it should be A. Increased reaction rate due to the increased number of collisions between particles.
Answer:
In aqueous solution, HF is an acid, exist as a mixture of molecules and ions
CH3CN is none of the above, entirely in molecular form
NaCIO4 is a salt, entirely as ions
Ba(OH)2 is a base, entirely as ions
Answer:
Eght: 0
Explanation:
The work formula is W = F*d where d is displacement (which means the direction matters)
Same amount of work.

Time does not matter in Work. Force and Distance do.
F = 50 N
s = 0 The only work you have done is move the ball above your head. Thereafter you just held it.
t = 15 but no work is done. Tell your tired muscles that as they try and deal with holding a 5 kg mass above you head.
W = 0
Nine
Again from the last question you should be able to tell that time does not matter. The force is the same for both of you (that's why he's your identical twin).
So the work is the same. You both weigh the same. You both went the same distance.
