PLS HELP Nitric oxide and bromine were allowed to react in a sealed container. When equilibrium was reached PNO = 0.526
atm, PBr2= 1.59 atm, and PNOBr = 7.68 atm. Calculate Kp for the reaction.
2NOBr(g) 22NO(g) + Br2(g)

What is important to study for nios grade 12 chemistry? i have only one month left.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
