Step-by-step explanation:
Debate: The debate was regarding slavery in the Missouri. The compromise was that Missouri would have slaves, but no future states could have slaves. The situation made clear that some people work to end slavery but some slave-owning states were not ready to give up slavery.
Missouri Compromise: 11 states of Missouri are Free states and 11 other states are under slavery. People in Missouri wanted slavery. In 1820, Laws are passed to maintain balance of power between slave and free states.
Senator Henry Clay convinced Congress to accept the Missouri Compromise. So Maine was admitted into the Union as a free state, and Missouri as a slave state.
