Why does the pressure of a gas increase when you increase the temperature? *
1 point
Increasing the temperature increases the size of the gas molecules, which then can put more pressure on the balloon walls.
Increasing the temperature decreases the volume, causing molecules to strike the balloon walls more frequently.
Increasing the temperature causes gas molecules to move more rapidly, striking the balloon walls more frequently and with greater force.

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
