4) Ramon is playing soccer. The ball comes straight at him, and he kicks it to a player on his right. His kick is an example of A) a pull that stops the ball. B) a force that changes the roll of the ball. C) a pull that creates the motion of the ball. D) a force that changes the direction of the ball. Eliminate

I took a usatestprep with this same question so i know the answer is D

Hopefully you find this helpful. :)

stupid i wont let you get a chance

explanation:

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
