when water is added to solid calcium carbide, CaC2, acetylene gas, C2H2, and calcium hydroxide, Ca(OH)2 are produced.
how do i write a balanced equation for the reaction.
No, you did not start off with that equation. It is NOT CaC2 + C2H2. I agree that the problem is not stated that clearly; however, it says "When water is added to calcium carbide, CaC2, It should have a semicolon or something here to break up the sentence or just start a new sentence THEN acetylene, C2H2, and calcium hydroxide, Ca(OH)2, are produced. So the reactants are CaC2 and H2O. The products are C2H2 and Ca(OH)2.
CaC2 + 2H2O ==> C2H2 + Ca(OH)2
we started off with this equation below
CaC2 + C2H2 --> Ca(OH)2 (right?)
then as per DrBob222 its balanced below,
CaC2 + 2H2O ==> C2H2 +Ca(OH)2
ok this is how I start by trying to balance this equation.
on the reactant side
there's 4C, 1Ca, and 2H and on the product there's 1Ca, 2H, 2O
is it possible to include the 2Oxygen on the reactant side and why can you explain please
To write a balanced equation for the reaction between water and solid calcium carbide (CaC2), you need to follow a few steps.
Step 1: Write the chemical formula of calcium carbide (CaC2) and water (H2O).
CaC2 + H2O
Step 2: Identify the products formed. In this reaction, acetylene gas (C2H2) and calcium hydroxide (Ca(OH)2) are formed.
CaC2 + H2O → C2H2 + Ca(OH)2
Step 3: Balance the equation. Start by balancing the elements other than hydrogen and oxygen.
Since there is only one calcium (Ca) atom on each side, the equation remains unbalanced.
CaC2 + H2O → C2H2 + Ca(OH)2
Now, let's balance the hydrogen (H) atoms by placing a coefficient of 2 in front of the water molecule on the left side of the equation.
CaC2 + 2H2O → C2H2 + Ca(OH)2
Next, balance the oxygen (O) atoms by placing a coefficient of 2 in front of the calcium hydroxide (Ca(OH)2) on the right side of the equation.
CaC2 + 2H2O → C2H2 + 2Ca(OH)2
Now the equation is balanced, as there is an equal number of each type of atom on both sides.
The final balanced equation is:
CaC2 + 2H2O → C2H2 + 2Ca(OH)2
