Find out the concentration of an HBr solution if a 40.00mL aliquot of the solution yields 0.5733 g AgBr while added to a solution with an excess of Ag ions. The Ksp of AgBr is 5.0 × 10-13.
A conducting sphere of radius 10 cm has an unknown charge. If the electric field 20 cm from the centre of the sphere is 1.5 × 103 N/C and points radially inward
Propane (C3H8) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation for this reaction is C3H8 + 5 O2 ® 4 H2O + 3 CO2. What volume of carbon dioxide is produced when 2.8 L of oxygen are consumed?
A 17.0-g sample of ice at -19.0°C is mixed with 101.0 g of water at 87.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
there is no measurable difference between final and initial pH - that is why it is called a buffer E. final pH is 0.16 pH units lower than original pH
How would I write a balanced chemical equation for the dissolving of copper carbonate in water and how would I be able to calculate the concentration of copper in the saturated solution from this
Effusion describes, A) the process by which a gas spreads out through another gas B) the process that describes the collisiions that occur between gas molecules
How is electronegativity used in determining ionic and covalent character of the bonding between two elements. And how do you tell if between two componds which is more ionic/covalent
A compounds 'H NMR spectrum illustrates resonance at 5.47 and 3.94 ppm explain what possible structural subunits does the compound contain
Find the volume of 1.00M KOH which must be added to 200mL of 1.00M glycolic acid (pKa=3.83) to produce a buffer solution
(A) How many grams of solid Pb(IO3)2 can be dissolved in 950.0 mL of a 0.01 M Pb(NO3)2 solution. (B) How many g of solid Pb(IO3)2 can be dissolved in 950mL of pure water if the Ksp= 3.5E-13
Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm.
