Problem- Give the chemical equation (including phases) that describes the combustion of butene, C4H8(g)Show all work, use additional paper if necessary.
During the laboratory exercise you will need 100.00mL of a 0.20M Ni^+2 solution and 25.00ml of a 0.10M Co^+2 solution. You will prepare the Ni^+2 solution from solid NiSO4 (X) 6H20 and the Co^+2 solution from solid Co(NO3)2 (X) 6H20
The IR spectrum of benzoic acid is included on page 3. Assign three specific absorbance bands (from the peak list below the spectrum) to the corresponding bond vibrations
Gaseous oxygen is held in 2 separate containers at identical temperature and pressure. The volume of container A is 7.92 L and it contains 0.209 mol of the gas. The volume of container B is 2.45 L. How many moles of the gas are in container B
Calculate the energy necessary to boil 100.0 g carbon disulfide, CS2, at its normal boiling point.
a what is the concentration of baoh2 in abaoh2 solution if the ph is 8.25?b what is the concentration of ammonium ion
The Ksp value for the dissociation of barium nitrate is 0.00464. The molar solubility of barium nitrate is consequently 0.105 M. If the concentration of the barium ion in a saturated solution of barium nitrate was raised to 0.178 M (this is not th..
A 21.496g sample of magnesium is burned in air to form magnesium oxide and magnesium nitride. When the products are treated with water, 2.813g of gaseous ammonia are generated. Calculate the amounts of magnesium nitride and magnesium oxide formed.
Concentration of NADH was found by using beer's law using 6.22 mM cm-1 as extinction coefficient. Concentration of NADH = .0212 mM. Moles of NADH that are present in 1.02 mL sample was found by : .0212 mM x 1.02 mL = .021624 mM/mL
At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3. H2(g)+I2(g) 2HI(g) Kc=53.3 At this temperature, 0.800 mol of H2 and 0.800 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present..
