Choose the situation below that would result in an endothermic ΔHsolution.
Bess [88]

Answer:

Option A - When |ΔHsolute| > |ΔHhydration|

Explanation:

A solution is defined as a homogeneous mixture of 2 or more substances that can either be in the gas phase, liquid phase, solid phase.

The enthalpy of solution can either be positive (endothermic) or negative (exothermic).

Now, we know that enthalpy is amount of heat released or absorbed during the dissolving process at constant pressure.

Now, the first step in thus process involves breaking up of the solute. This involves breaking up all the intermolecular forces holding the solute together. This means that the solute molecules are separate from each other and the process is always endothermic because it requires energy to break interaction. Thus;

The enthalpy ΔH1 > 0.

Thus, the enthalpy of the solute has to be greater than the enthalpy of hydration.

Vein deposits are usually produced by _____. weathering density sorting hydrothermal solutions cementation
mart [117]

Answer:

Hydrothermal solutions

Explanation:

Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.

Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.

Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
