States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for a…

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained …

CHE 180 General Chemistry I Homework Chapter 1, continued 10. Exercise 92: The properties of a mixture are typically averages of the properties of its components. The properties of a compound may differ dramatically from the properties of the elements that combine to produce the compound. For each process described below, state whether the material being discussed is most likely a mixture or a compound, and state whether the process is a chemical change or a physical change. a. An orange liquid is distilled, resulting in the collection of a yellow liquid and a red solid.

A student measured a 6.790 g sample of a hydrated salt. After heating, the mass of anhydrous salt was found to be 4.501 g. Use these data to calculate: a) The mass of water in the hydrated salt.b) The percent by mass of water in the hydrated salt.

There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change. Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the entire sample, and that the sample is in a sealed box, so that no matter can enter or leave. Sample of Substance X Change 1 Change 1 is O impossible O O a chemical change a physical change Change 2 Change 2 is: impossible O a physical change O a chemical change Change 3 000 000 Change 3 is: O impossible O a physical change O a chemical change X
