For each of the following positive ions use the concept that a chemical compound must have a net charge of zero to predict the formula of the simple compounds that the positive ions would form with Cl-, S2-,N3-
The mass of the dry gas is 872 mg. A fragment of the tank indicates that the gas is a monoatomic element. Write out the full name of the gas.
Is this system at equilibrium? If not, will the amount of N(g) increase or decrease as the system proceeds to equilibrium at 4000 k in a fixed volume
The best available balances can weigh amounts as small as 10-5 g. If you were to count out carbon atoms at the rate of two per second, how long would it take to count a pile of atoms large enough to weigh (10-5g)?
1) Draw the form (structure) of ascorbic acid that is present at physiological pH (in the body; pH= 7.4). What diseases can be prevented and/or treated by the intake of ascorbic acid?
Calculate the pH at the points in the titration of 40.00 mL of 0.425 M NH3 for the reaction below. NH3(aq) + HNO3 ? NH4+(aq) + NO3?(aq) For NH3, Kb = 1.8x10-5. Enter your answer with 2 decimal places.
Calculate the volume of a sample gas at 5.75 atm if it occupies 5.61 L at 2.18 atm. (Assume constant temperature.)
Calculate the correct volume of sulfuric acid which will need to be added to neurallize the base. The chemical reaction involves Al(OH)3 and Fe2O3 reacting with KOH and H2SO4 with the end product being KAL(SO4)2*12H2O.
If the blocks were placed at a temperature of 20oC, what will be the force of compression when the temperature reaches 40oC? The contact area between the block is 0.20m2. Will fracture occure?
