The nucleus of 5He contains tow protons and three neutrons. Using the standard values for the fundamental charge and the mass of the proton and neutron, what is the charge to mass ratio of the 5He nucleus, in Coulombs per gram?
When 4.03 g of CH3OH was mixed with 6.33 g of O2 and ignited, 3.92 g of CO2 was obtained. What was the percentage yield?
Calculate the mass of nitrogen dissolved at room temperature in an 81.0L home aquarium. Assume a total pressure of 1.0 atm and a mole fraction for nitrogen of 0.78.
Find the molarity of a Ca(OH)2 solution,given that 363 mL of it is neutralized in a titration by 187 mL of 0.0058 M HNO3.
A 21.496 g sample of magnesium is burned in air to form magnesium oxide and magnesium nitride. when the products are treated with water, 2.813 g of gaseous ammonia are generated.
The standard enthalpies of formation of SO3(g), S(g) and O(g) are -359.7, +278.8 and +249.0 kJ mol-1, respectively. Use these data to calculate the average bond energy (in kJ mol-1) of the S=O double bond.
Consider the titration of 100.0 ml of .100M H2NNH2 by .200 M HNO3. Calculate the pH when the following volumes of HNO3 have been added
Suppose that for the precipitation of the stock solution of borzac, the solid borax reagent is contaminated with a water-souble substance that does not eact with HCl.
A reaction with a low enthalpy of reaction value is not spontaneous at low temperature but becomes spontaneous at high temperature.
