How do you do balancing equations in chemistry?
- Count each type of atom in reactants and products.
- Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
- Repeat steps 1 and 2 until the equation is balanced.

Is physics harder than chemistry?
Physics is the hardest major; it is harder than chemistry, biology, psychology, computer science, astronomy, biochemistry, and geology. The level of math and the number of abstract concepts in physics is unparalleled.
Is a chemistry major harder than biology?
Full Member. From what I understand, chemistry is much harder than biology as a major. You’ll have to take advanced courses such as physical chemistry, and at my school a more rigorous version of organic chemistry.
