How many grams of solid magnesium nitrate should be added to 500 mL of 0.118 M of sodium nitrate in order to produce an aqueous 0.25 M solution of nitrate ions?
A horse ate some ration that was equivalent to 4000. kJ. In this case assume that none of thatenergy was stored or used in the animal's body but that all of this energy was lost in the form ofperspiration
Calculate the change in pH when 8.00 mL of .100 M HCl(aq) is added to 100.0 ml of a buffer solution that is 0.100M in NH3(aq) and 0.100M in NH4CL(aq) change in pH=
In another experiment it was determined that for each mole of hydrocarbon, 7 moles of oxygen gas are consumed and 5 moles of CO2 gas and 3 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K

What is the maximum number of orbitals that can be identified by each of the following sets of quantum numbers?
What volume (V) of 1.80 M NaOH solution must you add in order to prepare an acetate buffer of pH = 4.87? (The pKa of acetic acid is 4.76.)
How does electron confinement in an ion or molecule affect its color?
The first ionization energy of Ne is 2081 kJ/mol. The sodium ion Na+ is isoelectronic with Ne, but the ionization energy for Na+ is 4560 kJ/mol. Why is it harder to remove an electron from Na+ than from Ne if they are isoelectronic
