Why are all guys the same. they all cheat and break my heart. why do they do it?

Not all guys will break your heart and act selfish. When you find the right one he will treat you like a queen and you’ll never have to worry about him being unfaithful. I know it doesn’t help a hurting heart, but you WILL find your soulmate one day! Just keep faith! Best wishes!

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
