Can someone help me with my AP Chem quiz on thermodynamics? Answer questions about the theoretical reactions given:.

Reaction 1: A2 (g) + B2 (g) ⇄ 2 AB (g) ΔHrx = 20 kJ/mole ΔS0298 = 80 J/mole K

(a) Is this reaction thermodynamically favored (spontaneous) under standard conditions? Justify your answer with a calculation. (Find ΔG0)

(b) Determine the value of the equilibrium constant (Keq) for this reaction at 298 K

(c) If 1 mole of A2, 1 mole of B2, and 1 mole of AB are all placed into a 1 L container at standard conditions, what will happen (increase, decrease, nothing) to the moles of AB in the container? Justify your answer.

Which of the following statements about acidic water is true? a. acid has no effect on the h, o molecules. b. the solution contains a larger number of oh ions than h, o ions. c. the solution contains a larger number of h, o ions than qh ions. d. the solution contains an equal number of h, o ions and oh ions. none of the above e.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl +4h2o enter the elemental symbol. view available hint(s) is reduced
