A chemist added an excess of sodium sulfate to a solution of a soluble barium compound to precipitate all of the barium ions as

barium sulfate, BaSO4. How many grams of barium ions are in a 441-mg sample of the barium compound if a solution of the sample gave 403 mg BaSO4 precipitate? What is the mass percentage of barium compound?

Answer:

  259.497 mg,   58.84%

Explanation:

BaSO₄ → Ba²⁺ + SO₄²⁻

to calculate the mole of BaSO₄

mole BaSO₄ = mass given / molar mass = 403 mg / 233.38 g/mol = 1.7268 mol

comparing the mole ratio

1.7268 mol of BaSO₄ yields 1.7268 mol of Ba²⁺

403 mg BaSO₄  yields     ( 1.7268 × 137.327 ) where 137.327 is the molar mass of Barium mol of Ba²⁺

441 mg BaSO₄  will yield   ( 1.7268 × 137.327  × 441 mg ) / 403 mg = 259 .497 mg

mas percentage of the Barium compound = 259 .497 mg / 441 mg × 100 = 58.84%

Which statement best describes a mechanical wave?
Minchanka [31]

Answer:

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.

Explanation:

While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.

Which two conditions can limit the usefulness of the kinetic molecule or theory in describing gas behavior
mafiozo [28]

The high pressure and the low temperatures are the two conditions, which can restrict the effectiveness of the kinetic-molecular theory in illustrating the behavior of the gas.  

At high pressures or at low temperatures, the real gases deviate substantially from the ideal gas behavior. Due to this, the two conventions of the kinetic molecular theory, where gas particles hold an insignificant fraction of the entire volume of the gas, and the force of attraction among the molecules of gas is zero would become uncertain.
