There is an acid that smells like sweaty socks. When alcohol is added to it and the mixture is heated, no change is visible, but a new odor of sweet apples fills the room. Which of the following is the best explanation for this observation? A. a chemical change has taken place and no new substance was produced. B. a physical change has taken place and no new substance was produced. C.a chemical change has taken place and a new substance was produced. D. a physical change has taken place and a new substance was produced.

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

sure im new too!

explanation:

catya that's not even a b or c
