Answer: 218.4 g of will be produced from 3.9 moles of
Explanation:
The balanced chemical equation is:
According to stoichiometry :
1 mole of produce = 1 mole of
Thus 3.9 moles of will produce= of
Mass of
Thus 218.4 g of will be produced from 3.9 moles of
Answer:
A) CaF 2 (Calcium Fluoride)
C KBr (Potassium Bromide)
D) Mgl 2 (Magnesium Iodide)
Explanation:
All the above are electrolytes, because of their ability to dissociate/ionize when dissolved. Strong electrolytes completely ionize when dissolved, and not neutral molecules are able to form in the solution. Electrolytes are substances that conduct electric currents as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals (cathode and anode) of an electric circuit, respectively.
Answer:
4.3x10⁻⁵ mol/L.
Explanation:
Hello there!
In this case, since the dissolution of silver phosphate is not completely achieved due to its low solubility in water, we can represent this as an equilibrium problem by which it separates into silver and phosphate ions:
Which are slightly soluble in water; it means that the equilibrium expression is:
Thus, since we know the solubility product and the concentration of these ions in a saturated solution is represented by the reaction extent , we can write:
Thus, solving for we obtain:
Thus, the molar concentration of silver ions is 4.3x10⁻⁵ mol/L.
Best regards!
