Juan made the following bar graph shown to represent the relative distances of four different astronomical bodies from earth. the title of the bar graph is distance of bodies in space from earth. four bars are labeled a, b, c, and d. bar c is the shortest. bar d is about three times the size of bar c. bar a is about six times the size of bar c. bar b is about eight times the size of bar c. if d represents mars, which of the following could be represented by b and c?

output?

explanation:

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
