1. 1.00 mole of an ideal gas in a diathermal piston has an initial volume of 10.0L, an initial internal pressure of 2.48 bar and a temperature of 25.0oC. The gas is compressed isothermally to a final volume of 1.00L. Calculate the amount of work done if the compression is done is done: 1. (10 pts) Irreversibly, in one step with an applied pressured (Pext) of 25.0 bar.

The speed of light is around 6.706×10^8 miles per hour. what is the speed of light in units of miles per minute?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

The data below were determined for the reaction shown below. s2o82– + 3i – (aq) → 2so42– + i3– expt. # [s2o82–] (m) [i –] (m) initial rate 1 0.038 0.060 1.4 × 10 – 5 m/s 2 0.076 0.060 2.8 × 10 – 5 m/s 3 0.076 0.030 1.4 × 10 – 5 m/s the rate law for this reaction must be:
