The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

Unit 210 Support Learning Activities Outcome 1 1.1 Before Monday’s maths lesson started I met with the teacher and planned for today’s lesson. We evaluated what had happened‚ planned what we wanted to happen and then the fun bit teaching. We talked about two children who are finding maths hard. First of all we decided to move two children‚ who I noticed were copying each other’s work. In their new seats they couldn’t copy anyone‚ I then handed out the maths books and asked them to turn to the correct

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

RADICAL HALOGENATION AND GAS CHROMATOGRAPHY Abstract In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1‚1-dichlorobutane had 2.5% per Hydrogen; 1‚2-dichlorobutane had 10%; 1‚3-dichlorobutane
