PLEASEEE FAS I HAVE A TEST NOW! Tom's dad placed a candle in a bowl . a little while later , tom opened a bottle of pepsi and poured it quickly into the bowl. what will happen
1. the candle and flame will be unaffected
2. the candle flame will burn brighter
3. the candle will break
4. the candle flame will be put out
5. all of these

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
