Silver tarnish is the result of silver metal reacting with sulfur compounds, such as H2S, in the air. The tarnish on silverware (Ag2S) can be removed by soaking in a solution of NaHCO3(baking soda) in a basin lined with aluminum foil.
1) State a balanced equation for the tarnishing of Ag2S. do not include phases
2) Explain how many electrons are transferred per mole of silver?
3) State a balanced reaction for the reaction of Ag2S with Al metal and H2O to produce Al(OH)3,H2S and Ag metal.
The specific rotation of Compound X is +15.2o. A mixture of Compound X and its enantiomer are placed in the polarimeter and the observed rotation is -5.1o. Which enantiomer is in excess? (+ or -) Calculate the enantiomeric excess.
The initial rate of a reaction 2A + 3B -> C + 2D was measured using different initial concentrations of A and B. Use the information in the table to determine the rate law for the reaction.
The k1 is on top of the right pointing arow and k2 is below the left pointing arrow and the arrows are like they are in equilibrium. The k3 is above the lone arrow in the second reaction. In the find expression part the N02 is a subscript of P
one mole of nitrogen gas n2 is confined within a cylinder at the temperature of twenty five degree celsius and heated
A beaker with 115 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 5.70 mL of a 0.480 M HCl solution to the beaker.
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
