Observations of Chemical Changes Objectives: (1 of 20 points) The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. To associate chemical properties with household products Background Information: (2 of 20 points) Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that indicate a chemical change

Challenge #1 — The Penny Problem: The first challenge to complete is the Penny Problem. The radio station is giving the winner of this challenge a prize pack that includes tickets to see his or her favorite band in concert. To start off the challenge‚ the radio station has placed pennies in a cylindrical glass jar. Each penny is 0.75 inches in diameter and 0.061 inches thick. If the cylindrical glass jar containing the pennies has a diameter of 6 inches and a height of 11.5 inches‚ how many pennies

it is recommended sex offenders involuntarily undergo chemical castration which will influence nonviolent society. This effect has the tendency of a non-threatening environment with its extended treatment on sex hormones to reduce the levels of testosterone‚ desires‚ and unwanted fantasies. Depending on the offender’s mental stability‚ they will be released from prison after this method. As members of our community‚ one should ask‚ “Is chemical castration an appropriate punishment for sex offenders

Medication Storage: safe practice for storing medication is to always keep it in a secure safe place‚ make sure the key is held by an authorised people only. Always keep the medication in the correct temperature‚ light and humidity. The medication MUST be kept in the container in which it was dispensed from the pharmacy in. Use: staff giving the medication needs to be trained in relation to administration‚ infection control and non-touch technique. Disposal: safe practice in disposal of medication is

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.
