It is a type of equilibrium constant Assuming the heat absorbed by the styrofoam is negligible, calculate the expected final temperature Make a buffer solution with the following specifications
Water Leak Detector - Banlight
Ph= 5.2, volume= 3 l, total concentration of major species= 1m
A.) name the components b.) how many grams of each component would you use to make the 3 l of solution
Please show the work so i can learn Calculate the concentration of the reactant 60 S after initation of the reaction b How long would it take for the concentration of the reactant to drop 1/8 of its initial value?
To be sure you could check the moles of both mg and hcl and find out which produces the smaller amount of h2 gas But assuming that the mg is the limiting reagent, it should have no effect on your experimental value of r. Methanol and ethanol form a nearly ideal solution over a wide concentration range What is the vapor pressure of a 33.4% by weight solution of methanol in ethanol at 40.0 celsius?
A 0.77mg sample of phosphorous reacts with bromid=ne to form 10.70mg of bromide
What is the empirical formula od the phosphorous bromide? The equation for the reation for sodium formate with sulfuric acid is shown below The vapor pressure at water at 22oc is 19.8 torr Caluculate the percentage of sodium formate in the.
A student reacted 0.2200 g of zinc (zn) with excess hydrochloric acid (hcl) to generate hydrogen gas (h2) in a 25°c laboratory Given that the pressure of the gas is 0.80 atm and r = 0.0821 l*atm/mol*k, calculate how many milliliters (ml) of hydrogen gas could be generated. A coffee cup calorimeter contains 480.0 grams of water at 25 degree c 380.0 grams of water at 53.5 degrees celsius 525.0 grams of water at 65.5 degrees celsius
