Using the graph below, which of the following is a gas?
a
NaCl
b
Ce2(SO4)3
c
KCl
d
NaNO3
Based on the graph, none of the options provided are gases. The graph represents the solubility of different substances, and gases are not included in this graph.
To determine which of the given substances is a gas using the graph, we need to examine the boiling points of each compound. Unfortunately, the graph you mentioned is not provided in your question. However, I can still provide a brief explanation on how to determine whether a given compound is a gas based on its boiling point.
Typically, gases have lower boiling points compared to solids and liquids. At room temperature (around 25°C or 77°F), most gases exist as gases, while solids and liquids exist in their respective states.
Therefore, if the boiling point of a compound is below room temperature, it is likely to be a gas. Conversely, if the boiling point is above room temperature, it is more likely to be a solid or liquid.
Without the graph, it is not possible to determine the boiling points of the substances you provided. To correctly identify which of the given compounds is a gas, you would need to refer to their known boiling points or conduct further research to obtain the information needed.
