Which of the following shows the correct sequence of energy flow, as the different types of energy are converted from one type to the other in each stage of the process? (Look at the model) a Chemical potential energy → Electrical energy → Thermal energy → Sound energy b Thermal energy → Chemical potential energy → Electrical energy → Sound energy c Chemical potential energy → Thermal energy → Electrical energy → Sound energy d Electrical energy → Thermal energy → Chemical potential energy → Sound energy

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.

Which of the following are sources of revenue for media companies? a. direct sales to producers b.advertising and subscriptions c. online purchase d. capital investments

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
