The solubility of barium hydroxide in water at 20 degrees Celsius is 1.85g/100 water. a solution is made up of 256 mg in 35.0 g of water. is the solution saturated. if not . how much more barium hydroxide needs to be added to make a saturated solu..
Consider the following equilibrium reaction that has achieved a state of dynamic equilibrium. In a 3.00 L container, the following amounts were determined at 400ºC: 0.0420 mole N2, 0.516 mole H2 and 0.0357 mole NH3. Determine the value of Kc
For the following electrochemical cell Co(s)| Co 2+ (aq, 0.0155 M)|| Ag+ (aq, 3.50 M)|Ag(s) Write the net cell equation. Phases are optional. Do not include the concentrations.
why doen't the mass number decrease? (because there is one less neutron). But the atomic number increases due. What happens to the electrons?
The oxygen atom with its 2s orbital forms a s bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms with their 1s orbitals each form a s bond with one of the three sp2 hybrid orbitals of the carbon atom.
A sample of 0.2140 g of an unknown monoprotic acid was dissolved in 25.0 mL of water and titrated with 0.0950 M NaOH. The acid required 27.4 mL of base to reach the equivalence point.
