Calculate the mass percentage of cobalt in Co3(PO3)2.
Ethylene, C2H4, and water react under appropriate conditions to give ethanol. The reaction is C2H4(g) + H2O(g) C2H5OH(g) An equilibrium mixture of these gases at a certain temperature
A student determines the molar mass of methanol. She found that the equilibrium temperature of a mixture of ice and pure water was 0.4 degrees C on her thermometer
Given the equilibrium pH will you have successfully reduced each metal ion level to below the MLC? Provide detailed calculations to support your answer.
Using curved arrows to symbolize electrons, write a complete reaction mechanism for the bromination of acetanilide to create p-bromoacetanilide.
Calculate the molarity of the solution. How many grams of KNO3 are needed to make 450 mL of a solution that is to contain 5.50 mg/mL of potassium ion?
A flask contains 0.310 of liquid bromine, . Determine the number of bromine molecules present in the flask.
An equilibrium mixture contains 0.750 mol of each of the products (carbon dioxide and hydrogen gas) and 0.200 mol of each of the reactants (carbon monoxide and water vapor) in a 1.00-L container.
Electrolysis - Aluminium extraction, a. Aluminium is extracted from its ore by an electrolytic process. One extraction plant uses an applied e.m.f. of 5 V, and a current of 225 000 A. One tonne of aluminium is extracted after 14 hours.
Calcium hydride, CaH2, reacts with water to form hydrogen gas. CaH2(s) + 2 H2O(l) → Ca(OH)2(aq) + 2 H2(g)
