You take three compounds consisting of two elements and decompose them. To determine the relative masses of X,Y, and Z, you collect and weigh the elements, obtaining the following data:
Elements in Compound | Masses of Elements
X and Y X=.04g Y=4.2g
Y and Z Y=1.4g Z=1.0g
X and Y X=2.0g Y=7.0g
a) What are the assumptions in solving this problem?
b)What are the relative masses of X,Y, and Z?
c) What are the chemical formulas of the three compounds?
d) If you decompose 21g of compound XY how much of each element is present?
alguien me puede dar una mano con esto?
el ultimo dice X y Y pero tal vez sea un error de tipeo y diga Z, igual ni idea como hacerlo sea la forma que sea
