Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases‚ and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles‚ test tubes‚ 24 well plate‚ Gas assembly with copper and plastic tubing and a #00 stopper‚ short stem pipet‚ rubber stopper #00 with one hole and a pipet tip with

The fizz produced when Alka-Seltzer tablet is dissolved in water is due to the reaction of sodium bicarbonate (NaHCO3) and citric acid (H3C6H5O7) 3NaHCO3(aq) + H3C6H5O7(aq) --> 3CO2 + 3H2O + Na3C6H5O7(aq) In a certain experiment‚ 5.00 g of sodium bicarbonate and 5.00 g of citric

What are physical and chemical properties? Give an example of each. Physical properties describe an object can be its weight‚ size‚ color‚ volume‚ etc. Chemical properties describe how one substance reacts with another such as dropping an Alka-Seltzer tablet into water. 5. What do forensic scientists do to collect and preserve soil samples? Soil samples are collected within a 100 yard radius of certain spots.

Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

and vinegar‚ and observed the limewater turning murky and grey‚ an indication of CO2. Then did the same with a well of bromothymol blue which indicated an acid. I exposed this gas to a flame and the flame extinguished immediately. I then combined alka-seltzer and water‚ and inserted the gas into the lime water again. I then tested the CO2 from my breath with the lime water. Data Table: Gas Hydrogen Flame reaction Loud pop and flame extinguished Glowing splint Limewater reaction Bromothmol blue reaction

Rachel Smith Design Lab: Kinetics Lab Introduction: ! Background Information- Effervescent tablets reduce stomach acid and help treat upset stomachs. The familiar fizzing you hear when you drop an Alka-Seltzer tablet into a glass of water is the result of a chemical reaction. After dropping the tablet into the water‚ the reaction causes the solid tablet to become dissolved and releases tiny bubbles of carbon dioxide. This reduces the time it takes for the medicine to work as it does not need to dissolve

flight I could have made my rocket shorter and thinner because the smaller the mass the greater acceleration. Doing this would improve the acceleration of the projectile in this case the rocket. Also to improve the acceleration I could add more alka-seltzer to the film case. Doing this would add a greater force to push off of which would make the rocket go higher and faster. Lastly I could have made the structure for the rocket more aerodynamic. To do this I would make the flaps triangles that
