The reaction has had a heat that is enthalpy of -22 kJ/mol. The exothermic process has been signaled by the negative sign.
The amount of energy that the system absorbs or releases to create the products is described as the heat of reaction.
The source of the reaction's heat is
H is equal to 3(413 Kj/mol) + 358 Kj/mol + 467 Kj/mol + 1070 Kj/mol = 3134 Kj/mol.
H prod equals 3(413 kj/mol) plus 347 kj/mol plus 358 kj/mol plus 467 kj/mol plus 745 kj/mol, or 3156 kj/mol.
H=3134 kj/mol - 3156 kj/mol = -22 Kj/mol
Negative findings point to an exothermic response.
A chemical process known as an exothermic reaction releases energy in the form of heat or light.

A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Answer:
Solution A is correct.
Explanation:
Strong acids or bases are assumed to dissociate completely when in a aqueous solution.
D. details about what happening
This problem is providing the atmospheric pressure at 2000 m altitude which is 560. mmHg and asks for this pressure in units of atmospheres, which after doing the calculations, the result is 0.737atm.
<h3>Atmospheric pressure:</h3><h3 />
In this case, we can firstly define the concept of atmospheric pressure, also known as barometric pressure, as that pressure exerted by a column of air over a specific point in space at a defined altitude.
<h3>Units conversion in pressure:</h3><h3 />
In order to get the correct conversion, we use the following equivalence statement relating mercury millimeters and atmospheres:
760 mmHg = 1 atm
Hence, the required conversion turns out to be:
