Explanation:

The Compromise of 1850 was a series of laws that admitted a series of situations, among them:

California was considered a free state, Utah and New Mexico territories were created and the question of slavery was left to the population of those states to decide and stronger fugitive laws were passed that made easier for southerners to recover fugitive slaves.

Slave trade was abolished in Washington D. C but slavery was not abolished. Slave ownership continued in Washington D. C because Southerners believed that if in the Union's capital slavery was banished, this would set a precedent.
