Addition of water to calcium carbide leads to the formation of calcium hydroxide and ethyne. Write the equation for the production of ethyne
No apps here.
CaC2 + 2HOH ==> Ca(OH)2 + C2H2
carbon monoxide is CO
carbon dioxide is CO2
The equation for the production of ethyne (also known as acetylene) from the addition of water to calcium carbide is as follows:
CaC2 + 2H2O → Ca(OH)2 + C2H2
In this reaction, calcium carbide (CaC2) reacts with water (H2O) to produce calcium hydroxide (Ca(OH)2) and ethyne (C2H2).
To write the equation for the production of ethyne (also known as acetylene) from the addition of water to calcium carbide, we first need to understand the chemical formula of these compounds.
The chemical formula for water is H2O, where H represents a hydrogen atom and O represents an oxygen atom. The chemical formula for calcium carbide is CaC2, where Ca represents a calcium atom and C represents a carbon atom.
When water is added to calcium carbide, a chemical reaction occurs. The water molecule splits into its constituent hydrogen and hydroxide ions, as follows:
H2O -> H+ + OH-
The calcium carbide reacts with the hydroxide ion in water to produce calcium hydroxide (Ca(OH)2):
CaC2 + 2H2O -> Ca(OH)2 + C2H2
The remaining acetylene gas (C2H2) is the ethyne we are trying to produce.
Therefore, the equation for the production of ethyne from the addition of water to calcium carbide is:
CaC2 + 2H2O -> Ca(OH)2 + C2H2
