A gaseous solute will <span> be able to be dissolve in a liter of liquid water by increasing the pressure of the gas. an example of this situation is the increase in solubility of carbon dioxide in sea water which turns it into an acidic environment for marines as pressure increases.</span>
Answer:
No
Explanation:
The answer would be no.
<em>Solid aluminium oxide cannot react with hydrogen gas to produce molten aluminium and water due to the fact that, on one hand, hydrogen as an element is not a strong enough reducing agent that can remove oxygen from the aluminium oxide. On the other hand, aluminium is more reactive than hydrogen and hence, cannot be displaced by hydrogen in solution.</em>
Answer:
100.14°C
Explanation:
The boling point elevation is a colligative property that describes the increasing in boiling point of a solution regard to the boiling point of the pure solvent. The equation is:
ΔT = Kf*m*i
<em>Where ΔT is boiling point elevation</em>
<em>Kf is boiling point elevation (0.51°C/m for water)</em>
<em>m is molality of the solution (7moles Ba(NO3)2 / 75kg = 0.09333m</em>
<em>i is Van't Hoff factor = 3 for Ba(NO3)2 (Because its dissolution produce 3 ions = Ba²⁺ and 2 NO₃⁻</em>
<em />
Replacing:
<em> </em>ΔT = 0.51°C/m*0.09333m*3
ΔT = 0.14°C is the boiling point elevation
As the boiling point of water is 100°C, the boiling point of the solution is:
100°C + 0.14°C =
<h3>100.14°C</h3>
<em />
The answer is MAGNESIUM OXIDE - MgO.
Good luck :)
<span>The atmosphere is composed
mainly of air molecules. And air molecules consist of 21% oxygen and 79%
nitrogen. Oxygen is used for a lot of things. It used for cellular respiration,
for humans to breathe and other complex chemical reactions that needs oxygen. Nitrogen
is one of the important nutrients mostly used in the soil of the plants. It is
used for protein synthesis. Nitrogen is also absorbed by the plants from the
and the soil to complete the necessary reactions. </span>
