A man heats a balloon in the oven. If the balloon initially has a pressure of 860.0 torr and a temperature of 20.0 °C, what will the temperature (in Kelvin) of the balloon be after he
increases the pressure to 3.00 atm? (Hint: Convert to atmospheres). Do not include
units in your answer.

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

the link still does not work even when adding it to the url bar

explanation:

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
