In reaction between 100.0 g calcium carbide, CaC2 and water (excess), calcium hydroxide, Ca (OH) 2, and ethylene gas C2H2 (also called acetylene) are formed.
1) Write down the balanced reaction equation includes states of
matter.
2) What is the mass of the ethin produced at the end of the
reaction?
3) The reaction gas is delivered in a balloon at 20 ° C and a
pressure of 2.00 atm. What is a balloon volume? View
calculations
4) What is the concentration of hydroxide ions at the end of the
reaction when the volume of the solution is 500.0 ml?
5) Athene hardly dissolves in water.
But calcium hydroxide dissolves well in water.
In contrast, ethin dissolves well in a carbon dioxide
solution.
But calcium hydroxide does not dissolve in carbon dioxide.
Explain.

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.

Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons.
