Which statement is true for the given equation? ZnI2 + Br2 Bromine will combine with zinc iodide during the reaction.
Bromine will replace iodine during the reaction.
No reaction will occur.
Bromine will replace zinc during the reaction.
Zinc iodide will decompose into zinc and iodine during the reaction

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

i have no clue hope you find the answer
