Explanation:
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.
Answer:
The theory follow a microscopic description of chemical behavior.
Explanation:
The volume decrease is a macroscopic observation that can be explained by a microscopic event.
The molecules that make the gas are invisible to the human eye, however, the way they behave are the reason for different properties of the gas. It is easy to understand this if we think about the gas molecules as moving balls in a box. If we take the same amount of balls to a smaller box (decreasing the volume), the balls will hit the walls of the box easier (increasing the pressure).
