3. Part 3 Step 2 asks you to balance the equation between oxalic acid and permanganate in an acidic solution. The unbalanced equation has been placed below. Rewrite it balancing the equation. (5 pts) MnO4 − + C2O4 + H+⟶ Mn2+ + CO2 + H2O 4. Using the balanced equation above, what is the mole ratio of MnO4 -to C2O4 ? (5 pts)

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
