4. You are studying the combustion of methane (CH4) and an Oxygen gas (O2) rich environment at STP. During your investigation you collected 32.4 g of liquid H2O from 22.4 L of CH4, 48.6 g of liquid +H2O from 33.6 L of CH4, and 64.8 g of liquid H2O from 44.8 L of CH4 A. Create a data table summarizing the theoretical yields for both products from your investigation in moles (mol), actual yields for H2O in grams (g), and percent yield for water

B. Analyzing your data, what relationship do you see between your reactants and products

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!
