A 1.44 g piece of metal was taken from a beaker of boiling water at 100 oC and placed directly into a calorimeter at 25.0 o C. The calorimeter heat capacity is 1.23 J/K. If the final temperature is 62.5 oC, determine the specific heat capacity of the metal.
A metal hydroxide with the general formula M(OH)2 has a Ksp value of 0.00076. Calculate the molar solubility of this metal hydroxide
The pH of a bicarbonate-carbonic acid buffer is 8.30. Calculate the ratio of the concentration of carbonic acid (H2CO3) to that of the bicarbonate ion (HCO3-).
Calculate the pKa value of the acid and determine the number of moles of acid initially present. When the reaction is complete, what is the concentration ratio of conjugate base to acid? How many moles of strong base were initially added
A series of chemicals were added to some AgNO3(aq). NaCl(aq) was added first to the silver nitrate solution with the end result shown below in test tube 1, NH3(aq) was then added with the end result shown in test tube 2, and HNO3(aq) was added las..
a mass of 2.50 g of hydrated copper sulfate is placed in a crucible and heated. On hesting, 1.59 g of white anhydrous copper sulfate is left behind. determine the ratio of water to copper sulfate.
Calculate the number of calories needed to increase the temperature of 50.0 g of copper metal from 21.0 degrees C to 75.0 degrees C. Given, the specific heat of copper is 0.382 cal/g x degrees C.
After the vessel was pressurized with hydrogen gas and heated to 80 degrees C, the monometer showed the initial pressure inside the "bomb" to be 77.2 atm. Assuming 100% yield, calculate the pressure that should be inside the "bomb" when the reacti..
What is the pH of a solution made by adding 6.21 grams of sodium fluroide, NaF, to 391 mL of 0.317 M hydrofluoric acid, HF? (Assume no change in volume takes place.)
In the chemical reaction used in automotive air-bag safety systems, N2(g) is produced by the decompositon of sodium azide, NaN3, at a somewhat elevated temperature:
