. How does decompression make someone sick?
Decompression makes dangerous gasses dissolve more completely in the bloodstream.
When gasses in the blood decompress they make the blood thinner, which makes the diver dizzy.
Decompression presses on the diver’s stomach and makes him or her feel sick.
The expanding gas creates bubbles in the blood that can block the flow of oxygen.

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
