Hey there!
Mg + HCl → MgCl₂ + H₂
Balance Cl.
1 on the left, 2 on the right. Add a coefficient of 2 in front of HCl.
Mg + 2HCl → MgCl₂ + H₂
Balance H.
2 on the left, 2 on the right. Already balanced.
Balance Mg.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation: Mg + 2HCl → MgCl₂ + H₂
Hope this helps!
A variable that stands alone and isn't changed by the other variables you are trying to measure. For example, if you’re trying to see if drinking milk affects a persons height, then the independent variable is the milk, and the dependent variable is the persons height change
FeCl3 very commonly reacts with phenol groups.
hope this helps!!
