Final answer:
The application of Missouri for statehood was a problem due to the imbalance of power in Congress and conflicts over the admission of Maine and the expansion of Missouri's boundaries.
Step-by-step explanation:
The application of Missouri for statehood was a problem because it upset the balance of power in Congress. Missouri's desire to enter the Union as a free state or as a slave state created a dispute over the representation of pro-slavery and anti-slavery states. This led to a fierce debate in Congress, known as the Missouri Compromise, which eventually resolved the issue.
Furthermore, Missouri's request for statehood was tied to the admission of Maine as a slave state. The citizens of Maine did not agree to this arrangement, causing further complications.
Lastly, Missouri's desire for more land in the West after becoming a state created conflict with the citizens of Kansas, as they did not agree with the expansion of Missouri's boundaries.
