Matter In Our Sourroundings Important Questions Not for coping to note Q. 1. What is a matter? Answer : Anything that occupies space and has mass is called a matter. For example:- Chalk‚ Milk‚ Sugar etc. Q. 2. Sodium chloride and sugar have same appearance. Are they same or different? Answer : They have different physical and chemical properties. So‚ they are different. Q. 3. All substances around us are alike. How? Answer : All substances can occupy space and have weight.

Exercise 1. What safety equipment is available to you while you do your experiments? How far are they from you while you are conducting your experiments? This includes fire extinguishers‚ phones‚ showers‚ etc. The safety equipment that I have access to while performing my experiments are as follows; shower‚ fire alarms and a telephone. They are all within ten feet from where the experiment will take place. 2. What is an MSDS? MSDS is a document that is required by Osha’s “Hazard

is to acquire the use of common and simple laboratory equipment. Brief Procedure: A Bunsen Burner: Examine burner‚ locate gas and air flow‚ determine the operation of each valve. Connect the Bunsen burner to a gas tap using a piece of rubber tubing.Close the needle valve and the air vent. Open the gas valve. Open the needle valve 1-2 full turns‚ listening for the sound of gas. Using the striker‚ light the burner. The flame of the Bunsen burner should be yellow and irregular in shape. Open the air-hole

Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given mass of a gas exerts is inversely relate to its

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins
