Asample of gas has a pressure of 1.5 atm and a volume of 3.5 l, what would be the pressure of this sample of gas if the volume decreases to 2.8 l? show all of the work used to solve this problem. (3 points)

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

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
