Can someone tell me if I have this correct, I am leaving something out, or if I need to start over. I am alittle confused about the balanced equation involving a reaction.
Write a balanced equation for the reaction of MG with HCI.
Mg+HCL---MgCl2=H2
Mg-1 Mg-1
H-1 H-1
Cl-1 Cl-2
Mg+2HCl---MgCl2+H2
Mg-1 Mg-1
H-2 H-2
Cl-2 Cl-2
You have correctly balanced the reaction equation. Keep up the good work! and thanks for showing your work, too.
It seems like you're on the right track, but there are a few errors in the equation you have written. Let's go through it step by step.
The reaction you're referring to involves magnesium (Mg) reacting with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2).
To balance the equation, you need to make sure that the number of atoms of each element is the same on both sides. Here's the correct balanced equation:
Mg + 2HCl -> MgCl2 + H2
Now, let's break down the equation to show how it is balanced:
On the left-hand side (reactants):
- Mg: There is one atom of magnesium.
- HCl: There are two atoms of hydrogen (H) and two atoms of chlorine (Cl), as there are two molecules of HCl.
On the right-hand side (products):
- MgCl2: There is one magnesium atom (Mg) and two chlorine atoms (Cl), which balances the chlorine atoms on the left side.
- H2: There are two hydrogen atoms (H), which balances the hydrogen atoms on the left side.
So, the equation is balanced with one Mg atom, two H atoms, and two Cl atoms on both sides.
Remember, balancing equations requires ensuring that the number of atoms of each element is the same on both sides by adjusting coefficients in front of the chemical formulas.
