Rewrite The Chemical Equation Below Correctly: − H 2 + H C L -H_2 + HCl − H 2 ​ + H Cl

Understanding the Basics of Chemical Equations

Chemical equations are a fundamental concept in chemistry, representing the transformation of one or more substances into another. A chemical equation consists of reactants, products, and coefficients that indicate the number of molecules involved in the reaction. In this article, we will focus on rewriting the given chemical equation, $-H_2 + HCl$, correctly.

The Importance of Balancing Chemical Equations

Balancing chemical equations is crucial in chemistry as it ensures that the law of conservation of mass is obeyed. The law states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element must be the same on both the reactant and product sides of the equation.

Rewriting the Chemical Equation

The given chemical equation is $-H_2 + HCl$. However, this equation is not balanced, as it contains a negative sign in front of the hydrogen molecule, $H_2$. This is not a valid representation of a chemical reaction.

Step 1: Identify the Reactants and Products

The reactants in the given equation are $-H_2$ and $HCl$. The product is not specified, but we can assume it to be a compound formed by the reaction between $H_2$ and $HCl$.

Step 2: Determine the Correct Formula for the Product

The product of the reaction between $H_2$ and $HCl$ is likely to be water, $H_2O$. This is because hydrogen gas, $H_2$, reacts with hydrochloric acid, $HCl$, to form water.

Step 3: Rewrite the Chemical Equation

Using the information gathered in the previous steps, we can rewrite the chemical equation as:

$$H_2 + HCl \rightarrow H_2O$$

Step 4: Balance the Chemical Equation

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. In this case, the equation is already balanced, as there are two hydrogen atoms on both the reactant and product sides.

Conclusion

In conclusion, the correct chemical equation for the reaction between hydrogen gas, $H_2$, and hydrochloric acid, $HCl$, is:

$$H_2 + HCl \rightarrow H_2O$$

This equation is balanced, and it represents the transformation of hydrogen gas and hydrochloric acid into water.
