Step-by-step explanation:
Under the federal system, there are powers that are denied to the national government. Under the federal system, certain powers are denied to the national government, such as denying the right to a trial by jury and creating ex post facto laws. State powers are also limited by the Constitution, such as not being allowed to coin their own money or maintain their own armies.
For example, the national government cannot deny people accused of crimes the right to a trial by jury, grant titles of nobility, or create ex post facto laws.
These powers are specifically prohibited by the Constitution to both levels of government. The Constitution also places limits on state powers, such as prohibiting states from coining their own money, taxing imports and exports from other states, and maintaining their own armies.
