Answer:
Measurements have shown that the concentration of salt in seawater is 35.5 g-L. Calculate the volume in liters of seawater that must be evaporated to recover 0.400 kg of salt. Be sure your answer has the correct number of significant digits
<span>The correct answer is 'freezing point depression'. Colligative properties depend on the concentration of molecules of a solute. Examples of other colligative properties are boiling point elevation or vapour pressure lowering. The salt causes ice on the side walk to melt because it lowers the freezing point. </span>
Answer:
8 atoms of oxygen.
Explanation:
Given parameter:
Mass of magnesium phosphate = 15g
Unknown:
Number of oxygen atoms = ?
Solution:
The formula of the compound is;
Mg₃(PO₄)₂;
Number of atoms oxygen = 2(4) = 8 atoms of oxygen.
If countries are on plate boundaries, such as Japan, they are more prone to earthquakes. If countries are above hot spots, such as Hawaii, they are more prone to volcanoes.
