A sample of pure tin metal (which forms Sn 2+ nitrate. that would be present at the equivalence point. ions) is added to 200 mL of a 1.5 M solution of copper (II) a. Identify and write out both the oxidation and reduction half reactions (2 pts) b. Use the balanced half reaction equations to determine the overall net ionic equation for the reaction. (1 pt) c. Identify any spectator ions in the reaction (1 pt) d. Determine the maximum mass of copper metal that can be collected after the reaction if the tin metal has a mass of 30.0 g. (1 pt)

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

the answer is na (sodium)

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
