Write a molecular, complete ionic and net equation for the reaction that occur, if any, when solutions of the following substances are mixed:
(A) Nitric acid and potassium carbonate
(b) Sodium bromide and lead nitrate
(c) Acetic acid and calcium hydroxide
(d) Calcium nitrate and sodium sulfate
(e) Ammonium chloride and lithium hydroxide
A mixture of NaCl and NaBr has a mass of 2.05 and is found to contain 0.72g of Na. What is the mass of NaBr in the mixture?
Suppose that aqueous solutions of barium nitrate and potassium carbonate are mixed. What is the name of the compound or compounds that precipitate
Find the total pressure for a mixture that contains four gases with partial pressures of 5.38 kPa, 4.52 kPa, 3.16 kPa, and 1.23 kPa.
Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the equation: PCl5(g) ? PCl3(g) + Cl2(g) At 250° 0.375 M PCl5 is added to the flask. If Kc = 1.80, what are the equilibrium concentrations of each gas?
Sodium phosphate is added to a solution that contains 0.0014 M aluminum nitrate and 0.078 M calcium chloride. The concentration of the first ion to precipitate (either Al3+ or Ca2+) decreases as its precipitate forms
An experimenter finds that she is unable to establish a premixed carbon monoxide flame when using an oxidizer composed of high-purity O2 (21%) and high-purity N2 (79%)
Although the actual process also requires water, a simplified equation for rusting (rust is shown as Fe2O3) is 4Fe(s) + 3O2(g) => 2Fe2O3(s) ?Hrxn = -1.65 x 103 kJ How much heat is evolved when 0.100 kg of iron rusts
Therefore an answer in U.S. customary units, such as miles per hour would not be accepted as correct. A car traveling with constant speed travels 150 km in two hours. What is the speed of the car?
Give structural formula ( dash, condensed, or bone-line) for five constitutional isomers of molecular formula C6H14O (remember that carbon is tetravalent, oxygen is divalent, and hydrogen is monovalent)
How many liters of H2 gas, measured at 752mm Hg and 85 degrees C, are required to synthesize 0.65mol of CH3OH? How Many liters of CO gas, measured under the same conditions are required? CO(g)+2H(g)=CH3OH(g)
Determine the molarity of acetic acid in a 15 ml sample of vinegar that requires 22.7 ml of a .550 M solution of NaOH
100 mL of a 0.125 M solution of HBr was titrated with a 0.100 M solution of KOH at 25 C. The equivalence point will be reached after addition of what volume of the titrant?
