Consider the galvanic cell with Sn2+/Sn and Ag+/Ag both prepared with NO3- as their anion and all solutions prepared at 1.0 M. What is the reduction half-reaction and does it occur at the anode or cathode? Also..what is the standard cell potential?
the carbon-carbon bonds would be alternately long and short. However, to consider the structures as resonance contributors (or to connect them by a double-headed arrow) violates a basic principle of resonance theory.
At 700.°C, the total pressure of the system is found to be 3.63 atm. If the equilibrium constant KP is 1.52, calculate the equilibrium partial pressures of CO2 and CO.
If 25.0 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy?
A sample of an ionic compound that is often used as a dough conditioner is analyzed and found to contain 7.591 g of potassium, 15.514 g of bromine, and 9.319 g of oxygen. What is the empirical formula for this compound? What is its chemical name?
suppose you have a solution that might contain any or all of the following cations: Cu2+, Ag+, Ba2+, and Mn2+. the addition of HBr causes a precipitate to form
Suppose that you were to fill a 1L beaker with only 200 mL of water and it is not deep enough to make the water level inside and outside the graduated cylinder the same.
Draw the structure of dimethyl sulfoxide. Include any nonbonding electrons on sulfur, and minimize formal charges by allowing sulfur to expand its octet.
