What is one way he constitution tries to prevent conflicts between federal and state government

Check and balances is the right answer

One way the constitution tries to prevent conflicts between federal and state government is by giving specific powers to the federal government.

Explanation:

In Article I, Section 8, the US Constitution grants specific powers and rights to the federal government, called "expressed powers", and some other powers that are not directly stated in the document but that are necessary and proper to enforce the "expressed powers." Furthermore, the Tenth Amendment also prevents conflict between federal and state government by reserving the powers not delegated to the national government "to the States respectively, or to the people."
