Explain why the ionization of water increases with a rise in temperature.
Explain the advantages of expressing concentration of solution in terms of formality.
Give an explanations for the fact that polar solids have a limit to their solubilities in water, whereas polar liquids may be miscible in all proportions?
Why are the liquids, carbons tetrachloride and water, immiscible? Why, then are the liquids, ethyl alcohol and water, miscible in all proportions?
Percentage methods for expressing the concentration of solution are widely used in chemical industries. Suggest why percentage methods might to preferable, in industrial plants, to other methods for expressing concentration.
The use of normality as a method for expressing concentration is limited largely to acids and bases. Why is the use of normality unsuited to the expression of concentration for solution of salt?
10.73 of fluorine is mixed with 24.73 grams of calcium.
a) Write balance calculate
b) What is the linuity reactant
c) What is the excess reactant
d) Calculate the theoretical yield of product formula
e) If 5.80 grams of calcium fluoride are produced in lab calculate the percent yield
PLEASE HELP ME
After it had cooled the dry marble and test tube weighed 17.56 g. I know it is difficult to see the tick marks for the volume of gas in the video so by the end I collected 35.3 mL of CO2. Calculate the theoretical yield of CO2 in liters (do a stoichiometry problem use three decimals)
After it had cooled the dry marble and test tube weighed 17.56 g. I know it is difficult to see the tick marks for the volume of gas in the video so by the end I collected 35.3 mL of CO2. Calculate the moles of carbon dioxide collected (assume STP and use 4 decimal places)
