Using the graph below, which of the following is a gas?
a
Ce2(SO4)3
b
NaNO3
c
KCl
d
NaCl
Based on the graph, it is not possible to determine which of the given options is a gas. The graph does not provide information about the physical state of the substances.
To determine which of the compounds is a gas using the given graph, we need to understand the physical state of each compound. The graph does not provide the necessary information to directly identify the compounds' physical states.
However, we can use general knowledge of compounds and their physical states at room temperature. Generally, gases are substances that are in a gaseous state at room temperature.
a) Ce2(SO4)3: This compound is a solid, not a gas.
b) NaNO3: Like Ce2(SO4)3, NaNO3 is also a solid and not a gas.
c) KCl: KCl is a solid at room temperature, so it is not a gas.
d) NaCl: Similar to the previous compounds, NaCl is a solid, not a gas.
Based on this analysis, none of the compounds (a-d) are gases.
To determine which of the compounds in the given options is a gas, we need to analyze the chemical formulas and the states of matter associated with each compound.
However, since you mentioned a graph without actually providing it, I am unable to refer to the graph directly. Please provide the relevant information from the graph or specify any other details that could help me in providing an accurate answer.
