Write a general equation that illustrates all acid-base reactions. using equation, what factor can be varied to observe their effect on HEAT
A steel cylinder contains 120. moles of nitrogen gas at a temperature of 32 C and pressure of 775 torr. After some of the nitrogen gas has been used,
How many grams of CaCl2 are needed to make 364.8 g of a solution that is 37.5% (m/m) calcium chloride in water? (Note that m/m has the same meaning as w/w.)
Bromothymol blue, ka = 1.6 x 10^-7, is yellow in its protonated form (HX) and blue in its ionized form (X-). At what PH will bromothymol blue be a perfect green color
what is the theoretical yield of zinc iodide, if a 2.0-g sample of zinc was used with 6.5 grams of iodine
Show why this chemical is dangerous, by showing chemical reactions for its formation in the environment and its reactions in the atmosphere.
Calculate the standard cell potential at 25 C for the reaction X(s)+2Y+(aq)?X2+(aq)+2Y(s) where ?H? = -651kJ and S = -371J/K.
suppose the pressure inside a pressure cooker reaches 1.3 atm. By using the vapor-pressure table, estimate the temperature at which water will boil in this cooker
What is the hybirdization of a centeral atom that has four sigma bonds and has no pairs of electrons?
At this point in the titration the system reches equilibrium and therefore Qsp for silver chromate is equal to Ksp of silver chromate and Qsp for silver chloride is equal to Ksp for AgCl. 1. Cal the equilibrium concentration for the chromate ion [C..
a gas sample containing 1.50 mol at 25 exerts a pressure of 400 torr. some gas is added to the same container and the temperature increased to 50 C. If the pressure increases to 800. torr, how man moles of gas were added to the container? assume a..
Determine the pH of a buffer prepared by mixing 0.675 moles of HC2H3O2 and 0.575 moles of NaC2H3O2 in enough water to give 1.00 liter of solution.
Will a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate mix and what is the net ionic equation that describes the chemical change. what about for a solution of calcium chloride and a solution of mercury (I) nit..
