Which statment always applys to the process of duffsion check all that apply 1. molucules move from high consuntration to low
2. molcules move from inside of the cell to the oustide to the outside of the cell
3. duffsion requires protein in the cell membrane
4.molcules are evenly dissributed at the end
5.duffison requirs energy

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
