The rate of decomposition of n2o5 in ccl4 at 317 k has been studied by monitoring the concentration of n2o5 in the solution. 2 n2o5(g) → 4 no2(g) + o2(g) initially the concentration of n2o5 is 2.36 m. at 177 minutes, the concentration of n2o5 is reduced to 2.16 m. calculate the average rate of this reaction in m/min.

Summarize possible ways in which phases of matter could combine to form a solution.

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?

How many liters of oxygen gas, at standardtemperature and pressure, will react with 35.8 grams ofiron metal? 4 fe (s) + 3 o2 (g) → 2 fe2o3 (s)
