Explain how the proposed admission of Missouri as a state threatened the Senate balance between free and slaveholding states

The Missouri compromise of 1820 was targeted at balancing representation and power between the free states and the slaveholding states. The senate admitted the Missouri as a slaveholding state while Maine was admitted as a free state.

The debate that threatened the Senate was when Missouri applied to become part of the union and also allow slave within its territory lead to arguement and counter argument which divided the congress into pro slave and anti slave divisions that went on for almost a year but the application of Maine as a free state calm down nerves that resulted into admittion of Maine as a free state and Missoiuri as slavesholding state to balance the equation.
