(apex) when a cup of water is dropped, as the cup falls, the water in the cup falls out true or false?

I think it would be false for the reason if you drop a cup of water it don't always fall or spill out.

False

Explanation:

When a cup of water is dropped the water does not falls out of the cup as the cup falls. Because both the cup and the water will experience the same acceleration due to gravity and hence both cup and water will fall together and not separately.

Thus, the answer is false as the cup and the water will fall together.

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 answer is c
