Ionic salt dissociate completely in water particularly in water at low concentration.
The molal freezing point of depression constant for water is 1.85kg/k/mol
therefore depression of freezing point =1.853 x 0.100 x 2.32=0.429 degrees celsius
hence solute freeze at - 0.429 degree celsius

4 Ga (s) + 3 O₂ (g) → 2 Ga₂O₃ (s)
where:
(s) - solid
(g) - gas
Explanation:
At high temperature gallium (Ga) will react with oxygen gas (O₂) to produce solid gallium(III) oxide (Ga₂O₃).

D.
This is in accordance with the law of conservation of energy.
Answer:
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that
