Consider the combustion of 1 kmol of propane with air at 1 atm. construct a single graph using h-t coordinates that shows the following: a. reactants' enthalpy, h, in kj versus temperature, over the range of 298–800 k for o = 1.0. b. repeat part a for =0.75. repeat part a for q = 1.25. d. products' enthalpy, h, for ideal combustion (no dissociation) versus temperature, over the range of 298–3500 k for 0 = 1.0. e. repeat part d for q = 0.75. f. repeat part d for ø = 1.25, using the water-gas equilibrium to ac- count for incomplete combustion.

In a reaction equation, where are the products located? a.) above the arrow b.) to the right of the arrow c.) to the left of the arrow d.) below the arrow

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
