Which of the following measurements are not listed in the proper mathematical relationship? (select all that apply)
PV=K
P/V=k
V/T=K
PV/T=k

pv/t=k and p/v= k

Explanation:

Boyles Law pv= k

Charles Law v/t= k

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

indium, and thallium have three electrons i think
