Of course!

Google says so:

The Kansas-Nebraska Act was passed by the U.S. Congress on May 30, 1854. It allowed people in the territories of Kansas and Nebraska to decide for themselves whether or not to allow slavery within their borders. The Act served to repeal the Missouri Compromise of 1820 which prohibited slavery north of latitude 36°30

So yes i am right??

Ok cool thanks!!

Yes, you are correct. The Kansas-Nebraska Act of 1854 conflicted with the Missouri Compromise of 1820 because it permitted the option of slavery north of the Missouri Compromise line. The Missouri Compromise had established a boundary line, known as the 36°30' parallel, where slavery was prohibited in the territories acquired from the Louisiana Purchase, except for the state of Missouri. However, the Kansas-Nebraska Act allowed the settlers in the Kansas and Nebraska territories to decide whether or not to allow slavery through the principle of popular sovereignty. This effectively undermined the restriction on slavery imposed by the Missouri Compromise.
