When 1 mol of methane is burned at constant pressure, −890 kj/mol of energy is released as heat. if a 4.19 g sample of methane is burned at constant pressure, what will be the value of ∆h? (hint: convert the grams of methane to moles. also make sure your answer has the correct sign for an exothermic process.) answer in units of kj.

Why is the structure of molecule important to its function?

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!
