Properties of Matter lab
By: Andy Wang

Purpose:
To use the physical and chemical properties of known substances to identify the components of an unknown substance. Materials:
Spot plate Magnifying glass Water (H2O) Hydrochloric acid HCL Baking soda (sodium bicarbonate) Potassium chloride (KCL) Sodium thiosulfate (NaS2O3) Sodium Nitrate (NaNO3) Chalk (CaC03) Procedure:
I decided to find the properties of the known substances by making a chart.
I put the substances on the left side and the properties on the right. Then, I dividing the chart into Physical and Chemical properties. My physical properties was divided into 4 components; State of matter, Colour, Clarity and Crystal form. The chemical properties was divided into water and HCL. Afterwards, I tested the substances one by one on the
Spot plate and recorded my observations. I would put the a little bit of the substance in the plate and examine it and recorded the physical properties. Then, I would put a little bit of the substance on another place in the plate and add water to see if it is soluble or not. I would then do the same with HCL. After I tested all the substances, I went to get the Unknown and tested its properties.

Chem: Temperature and Particles Vaporization Sublimation Essay

Chemistry 1: Unit 1 Review Caldwell 2013 The particulate nature of matter Review readings, powerpoints, labs, and worksheets. Unit 1 objectives Students will be able to: • apply the particulate model of matter to describing physical properties for the three states of matter and to discussing their properties (i.e. density, compressibility, etc...) The particle model for matter states that all matter is made of particles which are moving all the time. In solids they vibrate…

Essay Chemical Reactions and Equations

and Equations” lab was to observe physical and chemical properties associated with chemical reactions, to make note of/document the evidence of the chemical reaction, to practice balancing equations, to predict the products that form from a reaction, and to have an understanding; did the elements bond, break apart, or did they switch partners in the reaction (determine what happened to the reactant/s as they formed new product/s). The lab demonstrated the law of conservation of matter, in form and…

Volume and Density Essay example

In this lab, you will determine the density of several volumes of an unknown liquid solution called “solution X.” You must then use your data determine whether the density of the solution is an intensive or extensive. An intensive property is a physical property of matter that does not depend on the size or the amount of material in the sample. Color, for example is an intensive property; no matter how much strawberry Jell-O you have it’s always red. By contrast, an extensive property does depend…

Essay on study mode

Physical and Chemical Properties Purpose: Chemistry is the study of matter and the change it undergoes. The change is divided up into two classes, chemical change and physical change. In a physical change, one or more physical properties of a substance are altered without their being any new substances formed as a result. Some examples of physical properties include, size, shape, color, and physical phase. An example of a physical change is melting an ice cube. A chemical change results in the…

Temperature and Solubility Essay

Lab Report Now You See it, Now You Don’t Hypothesis: If the temperature grows warmer, then the solvent will dissolve faster. Introduction: Nymisha: With a program known as Logger Pro, we measured the temperature of the water, the solvent, in which a mystery substance was being dissolved within, or solute. The general temperatures of the water were hot, warm, and cold. The water ranged from 3.9 degrees Celsius to 59.2 degrees Celsius. Using the thermometer as a sort of stirrer,…
