You can balance it by inspection.

The process I typically follow is: Your equation is not balanced. #"Mn"color(white)(l) + "HI" → "H"_2 + "MnI"_3# Step 1: Begin with the trickiest formula. Put a 1 in front of #"MnI"_3#. This number is fixed and does not change until (if necessary) Step 5. #"Mn"color(white)(l) + "HI" → "H"_2 + color(red)(1)"MnI"_3# Step 2. Balance #"Mn"#. We have fixed #"1 Mn"# on the right, so we need #"1 Mn"# on the left. #color(blue)(1)"Mn"+ "HI" → "H"_2 + color(red)(1)"MnI"_3# Step 3. Balance #"I"#. We have fixed #"3 I"# on the right, so we need #"3 I"# on the left. Put a 3 before #"HI"#. #color(blue)(1)"Mn"+ color(orange)(3)"HI" → "H"_2 + color(red)(1)"MnI"_3# Step 4. Balance #"H"#. We have fixed #"3 H"# on the left, so we need #"3 H"# on the right. We have #"2 H"# atoms on the right, so we must multiply by 1.5 to get #"3 H"# atoms. #color(blue)(1)"Mn"+ color(orange)(3)"HI" → color(green)(1.5)"H"_2 + color(red)(1)"MnI"_3# All atoms should now between balanced, but we have a fraction in front of #"H"_2# Step 5: To eliminate fractions, multiply each coefficient by two. #2"Mn"+ 6"HI" → 3"H"_2 + "MnI"_3# Step 6: Verify that each atom is in balance. #bb"On the left"color(white)(l) bb"On the right"# #color(white)(mll)"2 Mn"color(white)(mmmm) "2 Mn"# #color(white)(mll)"6 H"color(white)(mmmmm) "6 H"# #color(white)(mll)"6 I"color(white)(mmmmml) "6 I"# The equation that is balanced is #color(red)(2"Mn"+ 6"HI" → 3"H"_2 + "MnI"_3)#

undefined To balance the equation Mn + 3HI -> H2 + MnI3, you need to ensure that the same number of atoms of each element are on both sides of the equation.
