Answer:
The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Answer:
<h3>Gallium(III) sulfide </h3>
Let us compute for the total moles that can be vaporized:
moles vaporized = 24 kJ / 40.6 kJ/mol
moles vaporized = 0.59 mol
The molar mass of water is 18 g/mol so the mass vaporized
is:
<span>mass vaporized = 0.59 * 18 = 10.64 grams</span>
Answer:
See explanation
Explanation:
If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.
Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.
