Solids do not take the shape of their container. If the melting and boiling points are both below room temp, you have a solid. If they're both above room temp, the compound is a gas. If the boiling point is above room temp and the melting point is below, the compound is a liquid.
- Locate the parentheses after the chemical formula, whether or not it is within the context of an equation.
- Identify the parentheses as (s) for solid, (l) for liquid, (g) for gas, or (aq) for aqueous solution.
How do you know if a compound is liquid or gas?
If they're both above room temp, the compound is a gas. If the boiling point is above room temp and the melting point is below, the compound is a liquid. Click to see full answer.
What is the difference between solid liquid and gas?
Also to know is, what is the difference between solid liquid gas? Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
What determines whether a condensed phase is a liquid or solid?
In addition, the shape of the molecules dictates whether a condensed phase is a liquid or a solid. Elements that exist as gases are mainly found in the upper right corner and on the right side of the periodic table. The following elements exist as gases: H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, and Rn.
How do you know if a compound is aq or s?
A compound may be aq or s, depending. The only way to know is the info at hand. NaCl is a familiar example. You know about both NaCl(aq) and NaCl(s). If I say something about NaCl, you need to somehow figure out whether it is the pure solid or a solution.
How do you know if a compound is liquid?

So we used aqueous to indicate that it's combined with water and it'sMoreBut it's combined with water. So we used aqueous to indicate that it's combined with water and it's an aqueous solution. So notice that we only see SMGs. In this chemical equation we could see gases.
How do you know the state of a compound?
The simple answer to your question is SOLUBILITY RULES. If the compound is soluble it gets labeled (aq). If it is insoluble, it gets labeled (s) and if it a gas it gets labeled (g). And finally, liquids, such as H2O get labeled (l).
How do you know if a compound is solid liquid or gas at room temperature?
Notice that the solids melt and boil above room temperature, the liquids melt below room temperature and boil above room temperature, and the gases melt and boil below room temperature. A solid has a fixed shape and volume that do not change with the shape of its container.
How do you determine the state of an element or compound easily?

But part of theMoreIf it is soluble it is aqueous. If it is insoluble it is a solid if it is soluble. But part of the compound is an exception it is a solid if it is insoluble.
How do you predict the states of matter?
The melting point of a substance is the temperature at which it melts or freezes. The boiling point of a substance is the temperature at which it boils or condenses. You can predict the state of a substance at a given temperature if you know its melting point and boiling point.
How do you know if a substance is a gas?
Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape.
How do you know something is a gas?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have a lower density than other states of matter, such as solids and liquids.
