The gas-phase decomposition of CH3CHO(g) occurs according to the equation CH3CHO(g) → CH4(g) + CO(g) and is second order. The value of the rate constant is 0.105 M–1s-1 at 490°C. If the concentration of CH3CHO(g) is 0.012 M initially, what will be its concentration 5.0 minutes later?

Which of the following units is not an official si unit? mole liter kilogram ampere

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.
