Answer:
Devolution, the transfer of power from a central government to subnational (e.g., state, regional, or local) authorities. Devolution usually occurs through conventional statutes rather than through a change in a country’s constitution; thus, unitary systems of government that have devolved powers in this manner are still considered unitary rather than federal systems, because the powers of the subnational authorities can be withdrawn by the central government at any time (compare federalism).

Answer:
- Liquid (molten metals/rocks)
- Silica
- Gasses
Explanation:
The magma is a product of the mantle layer. The temperatures in this layer are very high, and the pressure is also much higher than on the surface. This leads to creating a melt out of the rocks/metals in it, thus creating a thick liquid out of them. Apart from the liquid of molten rocks/metals, a major component of any magma is the silica, which actually determines its behavior ones it reaches the surface of the Earth. The third important component of the magma are the gasses. The gasses are forming bubbles in the magma, and depending on the amount of silica, they can remain trapped and than cause explosions on the surface, or they can escape the magma easily if the magma is not highly viscous.
Answer:
53.2%
Explanation:
- Write the mass of the elements in your molecule:
Mass of Si in 1 mol SiO2 =28.1g
Mass of O in 1 mol SiO2 =16x2g= 32g
- Now find the mass of your compound
Mass of compound= 28.1+32=60.1
- Divide each element's mass by the mass of the compound to find the percent by mass following this formula:
% by mass = (mass of element/mass of compound) x 100
% by mass of oxigen= (32g/60.1) x 100
% by mass of oxigen= 53.2%
I hope you find this information useful and interesting! Good luck!
