Answer: The sign of ΔH° for the reaction is positive.
Explanation:
Given: = 155 kJ/mol (1 kJ = 1000 J) = 155000 J/mol
The relation between and is as follows.
As the given value of is positive. This means that on further calculation the value of will come out to be positive.
Thus, we can conclude that the sign of ΔH° for the reaction is positive.
To solve number 18 you have to add the positive and negative to equal zero. For example for 18a it would be K2S ( the 2 is a subscript ) because you need 2 positives to cancel out the 2 negatives.
The moving of molecules from areas of high concentration to that of low concentration to gain energy is best described as passive transport
<h3>What is passive transport?</h3>
Passive transport is a type of membrane transport in which chemicals are moved across cell membranes without using energy. Unlike active transport, which uses cellular energy, passive transport uses the second law of thermodynamics to cause the movement of substances across cell membranes.
<h3>Why is passive transport important?</h3>
Passive transport processes are critical to homeostasis. They maintain proper conditions inside the cell and the organism as a whole by letting chemicals to pass into and out of the cell.

The answer would be Chope it helps
When the chemicals combine, it creates a chemical reaction or "eruption"
