You would set it up like this…

Actual yield/Theoretical yield x 100

16/24 x 100

The answer is 66.7% or 67%

%yield = actual/theoretical x 100%

%yield = 16/24 x 100%

% yield = 67%

Which of the following graphs correctly represents the relationship between the temperature and the volume of an ideal gas that
Anon25 [30]

Answer:

The graph of the relationship of temperature one volume is a graphical representation of Charles law.

Explanation:

The graph shows the relationship between volume vs temperature plotted at constant pressure for a fixed amount of gas. As can be observed from the graph, the volume increases with an increase in the temperature, and vice versa. Thus, volume is directly proportional to temperature at a constant pressure, which is the statement of Charles's law.

Volume is plotted on the y- axis, and temperature is on x-axis. The graph is a straight line with a positive slope passing the origin. The equation of the line is V = kT, which is the equation of Charles's law. The slope of the line is k. As temperature approaches zero kelvin, volume also approaches zero.

Real gases do not obey Charles's law at low temperatures. As temperature approaches absolute zero (0 K), the real gases start deviating significantly from Charles's law.

monitta

Answer:

4x^3

Explanation:

Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.

Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.

For AB2(s)< -------> A(aq) + 2B(aq). But solubility of AB2= x

Ksp= x × (2x)^2

Ksp= 4x^3

How does H2So4 break up to h+ &amp; hso4 - ?
Katena32 [7]
H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is 

H2 SO4 = H + HSO4- 

This can further release H+ and dissociate SO4- instead already
