We will begin by observing in a quantitative way decomposition of baking soda (NaHCO3). When NaHCO3 is heated, it decomposes to Na2CO3, CO2 and H2O. In this experiment, we will decompose a known amount of NaHCO3 and measure the mass of the Na2CO3 produced (actual yield). We will then compare this to the theoretical value using the percent yield calculation.

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!
