In an experiment solid calcium carbide (CaC2) is combined with water (two hydrogens and one oxygen)...
Acetylene gas produced in the experiment in question #2 is the gas used in welding torches. Recall its formula is two carbons and two hydrogens. You could take the balloon full of acetylene from question #2 and tie it to the end of a meter stick. Then if you hold the balloon near a burner flame, the balloon will explode as the oxygen from the air (O2) combines with the acetylene (two carbons and two hydrogens). The exothermic reaction produces...
The following demonstration takes place in a two-step process: First, solid calcium carbide (CaC2) reacts with liquid water to produce acetylene gas (C2H2) and aqueous calcium hydroxide. Second, the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equation for each reaction that is occurring.
In an experiment in the lab, a white solid called ammonium chloride (NH4Cl) is heated and decomposes to form two gases, hydrogen chloride (one hydrogen and one chlorine) and ammonia (one nitrogen and three hydrogens). The reaction is conducted in a closed flask to capture the gases that are produced. Observations from the experiment are recorded below: . . OBSERVATIONS Mass of flask 132.6 g Mass of NH4Cl and flask 153.8 g . Observations of NH4CI: It is a crystalline...
