Use the table provided below to help solve the problem. Sam conducts an experiment to determine an unknown substance. After measuring the unknown substance on a balance, he recorded a mass of 62.5 grams. The initial temperature of the metal was 22oC and that at the end of the experiment the thermometer read 78oC for the metal. His teacher told him that the amount of heat produced was 450.1 joules. Determine the identity of the unknown metal.

You must SHOW WORK and describe how you determined the identity of the unknown metal.

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!
