15 points Please help me Part C Place the copper strips in test tubes 3 and 6. If the strips are too wide, you may bend
them to fit them in the test tubes.
Place the magnesium strips in test tubes 1 and 4. If necessary, use the stirring rod to push
the strips down until they're entirely submerged.
Place the zinc strips in test tubes 2 and 5.
Record your observations of the appearance of the substances in the test tubes
immediately after adding the metal strips. Include any evidence of a chemical reaction. If
there's no evidence of a reaction, write "no reaction."

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

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

it's filtration, but this is an assumption so my apologies if i got this

distance, luminosity, brightness, radius, chemical composition, and temperature
