Hydrogen reacts with chlorine to form hydrogen chloride (HCl (g), Delta. Hf = –92. 3 kJ/mol) according to the reaction below. Up

per H subscript 2 (g) plus upper C l subscript 2 (g) right arrow 2 upper H upper C l (g). Which statement is correct? Use Delta H r x n equals the sum of delta H f of all the products minus the sum of delta H f of all the reactants. The enthalpy of the reaction is –184. 6 kJ, and the reaction is exothermic. The enthalpy of the reaction is –184. 6 kJ, and the reaction is endothermic. The enthalpy of the reaction is 184. 6 kJ, and the reaction is endothermic.

When 5 grams of kcl are dissolved in 50. Grams of water at 25°c, the resulting mixture can be described as
GaryK [48]

Answer:

3. Homogenous and unsaturated

Explanation:

Since your given information mentions 50 grams of solvent and 5 grams of solute, you must double each amount because "

Table G Solubility Curves" in the Regents Chemistry Reference Table notates curves based off of 100 g samples of water. Therefore, you must look for how soluble 10 grams of KCl is in 100 grams of water at 25 degrees Celsius.

As the picture shows, 10 grams of KCl is well below the curve for saturation, meaning that the solution is undersaturated.

As for the second part of the answer, we can tell that the solution is homogenous (of uniform composition) because there is no possibility of the salt, KCl, falling out of solution and making the mixture heterogenous (of mixed composition).

Putting all of those ideas together, we can tell that the answer to this question is:

3. Homogenous and unsaturated

How does scoring high on the SAT help someone receive a full academic scholarship to college?
Brut [27]
Colleges often consider accepting students based on their test scores, as well as certain additional traits. Not all students accepted to college have high SAT scores, however, higher scores increase chances of an academic scholarship. If you are looking for a full academic scholarship, high SAT scores will be beneficial due to the fact that most colleges select students mostly based on test scores. However, you will need additional high grades and test scores in order to be considered for a full scholarship.
