what is CAH2 + H20
The chemical equation CAH2 + H2O represents the reaction between calcium hydride (CAH2) and water (H2O). In this reaction, calcium hydride reacts with water to produce calcium hydroxide (Ca(OH)2) and hydrogen gas (H2).
The balanced chemical equation for this reaction is:
CAH2 + 2H2O -> Ca(OH)2 + 2H2
So, when calcium hydride reacts with water, it forms calcium hydroxide and releases hydrogen gas.
The chemical equation CAH2 + H2O represents the reaction between calcium hydride (CAH2) and water (H2O). Let's break down the equation and explain what happens in this reaction.
CAH2 is a compound made up of calcium (Ca) and hydrogen (H) atoms. It is a solid that reacts with water (H2O), which is a liquid.
In the reaction, CAH2 reacts with water to produce calcium hydroxide (Ca(OH)2) and hydrogen gas (H2). The reaction can be represented as follows:
CAH2 + H2O → Ca(OH)2 + H2
To balance this equation, we need to make sure that the number of atoms of each element involved in the reaction is equal on both sides. In this case, we have:
1 calcium atom (Ca) on both sides
2 hydrogen atoms (H) on the left side and 2 on the right side
2 oxygen atoms (O) on the right side
To balance the equation, we don't need to change the coefficients of the reactants (CAH2 and H2O) since they already have balanced atoms. However, we need to balance the products by adding a coefficient of 2 in front of water:
CAH2 + 2H2O → Ca(OH)2 + H2
This balanced equation shows that when calcium hydride reacts with water, it produces calcium hydroxide and hydrogen gas.
