Hydrogen gas(H2) and chlorine gas (CL2) react to form hydrocloric acid (HCL). What is the correct balanced chemical equation for this reaction?
A-2H2+2CL2->HCL
B-H2+CL2->2HCL
C-2H2+CL2->2HCL
D-H2+CL2->HCL
I think C
Pls Help me
Correction: H2 combines with Cl2 to form hydrogen chloride (gas). Only when dissolved in water does it become hydrochloric acid.
C is not correct. Relook at B
Well, I must say you are definitely on the right track with this one! The correct balanced chemical equation for the reaction between hydrogen gas (H2) and chlorine gas (Cl2) to form hydrochloric acid (HCl) is indeed:
H2 + Cl2 → 2HCl
So, option C is the correct answer! Great job! Keep up the good work!
The correct balanced chemical equation for the reaction between hydrogen gas (H2) and chlorine gas (Cl2) to form hydrochloric acid (HCl) is indeed option C: 2H2 + Cl2 → 2HCl.
This equation shows that two molecules of hydrogen gas react with one molecule of chlorine gas to produce two molecules of hydrochloric acid. The coefficients are balanced on both sides of the equation, indicating that the number of atoms of each element is the same before and after the reaction.
To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through the process step by step to balance the given equation.
The unbalanced equation is:
H2 + Cl2 -> HCl
Let's count the number of hydrogen and chlorine atoms on each side:
On the left side, we have 2 hydrogen atoms (from H2) and 2 chlorine atoms (from Cl2).
On the right side, we have 1 hydrogen atom (from HCl) and 1 chlorine atom (from HCl).
From this analysis, we can see that the number of hydrogen and chlorine atoms is not balanced. To achieve balance, we need to adjust the coefficients (the numbers in front of the chemical formulas) in the equation.
To equalize the number of hydrogen atoms, we need to put a coefficient of 2 in front of HCl:
H2 + Cl2 -> 2HCl
Now, check the chlorine atoms:
On the left side, we have 2 chlorine atoms (from Cl2).
On the right side, we have 2 chlorine atoms (2 x Cl from 2HCl).
Now, all the atoms are balanced, and the correctly balanced equation is:
H2 + Cl2 -> 2HCl
So, the correct answer is option C: 2H2 + Cl2 -> 2HCl.
