When divided by △t, (vf - vi) is used to determine which characteristic?

direction
speed
acceleration
displacement

I am absolutely sure that when divided by △t, (vf - vi) is used to determine Acceleration - the third option from the scale represented above. It is a special case when the acceleration is contstant 0. Hope you will find it helpful! Regards.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

Rn in the right answer
