A chemistry graduate student is studying the rate of this reaction: 2H3PO4 (aq) ---> P2O5 (aq) + 3H2O (aq)He fills a reaction vessel with and measures its concentration as the reaction proceeds: time (seconds) [H3PO4]0 0.03M1 0.018M2 0.011M3 0.0067M4 0.0041MUse this data to answer the following questions. Write the rate law of the reaction.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Which of the following is a conclusion that resulted from ernest rutherford’s scattering experiment? (will mark brainliest) a. the nucleus is negatively charged b. the atom is a dense solid and is indivisible c. the mass is conserved when atoms react chemically d. the nucleus is very small and the atom is mostly empty space

What is the average rate of the reaction between 10 and 20 s?
