An element X combines with oxygen to form a compound of formula XO2. If 24.0 grams of element X combines with exactly 16.0 grams
tensa zangetsu [6.8K]

Answer:

atomic mass of X is 48.0 amu

Explanation:

Let y be the atomic mass of X

Molar mass of O_2 is = 2×16 = 32 g / mol

X + O2 -----> XO_2

According to the equation ,

y g of X reacts with 32 g of O_2

24 g of X reacts with Z g of O_2

Z = ( 32×24) / y

But given that 24.0 g of X exactly reacts with 16.0 g of O_2

So Z = 16.0

⇒ (32×24) / y = 16.0

⇒ y = (32×24) / 16

y= 48.0

So atomic mass of X is 48.0 amu

conclusions: how is the difference in the physical properties of the powdered mixture components being used to separate them in
Advocard [28]
  • Sedimentation and Decantation is the process of setting of solid particles from a liquid either to produce a concentrated slurry or to clarify a liquid containing solid particles . The solid must not be mixed with liquid. For example- sand insoluble in water
  • Sublimation -  In this process solid phase is directly transformed  into vapour form without passing through liquid phase.This method is used in the purification of those substances which have sublimation property. At first the mixture should be sublimed before dissolution in liquid.
  • EX- Iodine , naphthalene, ammonium chloride etc. Here, NH4Cl is seperated by sublimation.
  • Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts. The process convert  the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains.
  • so, now by evaporation of the liquid solvent we finally get the salt that was dissolved in it that is NaCl.
