abbreviations are as follows: s = solid; l = liquid; g = gaseous; aq = aqueous, or soluble in water. Once you know the products of a reaction, you can use the solubility rules to see if you have an insoluble product, and thus, a precipitation reaction.

How do you know if an element is aqueous or solid?
- 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 something is aqueous?
How do you know if it is a solid?
Something is usually described as a solid if it can hold its own shape and is hard to compress (squash). The particles in most solids are closely packed together. Even though the particles are locked into place and cannot move or slide past each other, they still vibrate a tiny bit.
How do you tell if a molecule is a solid?
Is NaCl a solid or aqueous?
NaCl is a solid at room temperature, with a very high melting point (801 °C), similar to the melting points of silver (961.78 °C) and gold (1064.18 °C), although much lower than the decomposition temperature of diamond (3550 °C).
Is H2O aqueous or solid?
H2O is a liquid.
Is Naoh a solid liquid gas or aqueous?
At room temperature, sodium hydroxide is a white, odorless solid.
Is HCl a solid liquid gas or aqueous?
hydrogen chloride (HCl), a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure.
How do solids differ from liquids?
solid: Relatively rigid, definite volume and shape. In a solid, the atoms and molecules are closely bonded that they vibrate in place but don’t move around. liquids: Definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.
Which characteristic distinguishes the particles of solids from liquids?
Hence the distinguishing physical characteristic between solids and fluids is having a fixed volume but not a fixed shape. Conclusion: Hence, solids have a fixed shape and fixed volume while liquids have only a fixed volume and no fixed shape and this is the physical characteristic that distinguishes them.
How do you know if a molecule is a liquid?
The particles that form a liquid are relatively close together, but not as close together as the particles in the corresponding solid. The particles in a liquid have more kinetic energy than the particles in the corresponding solid.
Is NH3 aqueous or solid?
NH3, normally found as a gas, it is caustic and harmful in longterm exposure. NH3 has a boiling point of -33 Celsius, and must be stored under pressure, or at low temperatures. Ammonia is regulated in the United States as a substance that is a non-flamable gas.
Is cacl2 aqueous or solid?
Calcium chloride, CaCl2, is a typical ionic halide and is a solid at room temperature.
Is na2so4 aqueous or solid?
Sodium sulfate is a neutral salt, which forms aqueous solutions with pH of 7.
Is CO2 aqueous?
CO2(aq) means carbon dioxide dissolved in an aqueous solution. “CO2(g)” means carbon dioxide as a free gas phase.
Is NaCl a solid?
NaCl(s) is solid sodium, usually crystals, that we use as table salt. The compound is in a crystalline structure with each compound lacking the energy to be mobile.
Is H2SO4 liquid or aqueous?
Sulfuric Acid H2SO4- A highly corrosive colorless to dark brown liquid. Used in applications such as paints, fertilizers, and detergents. It reacts with water to form hydrates and can also dehydrate in a concentrated form. Sulfuric Acid, H2SO4, is a clear liquid that is soluble in water.
Is na2co3 a solid?
It is white crystalline solid; It is one of the few metal carbonates which are soluble in water; It is alkaline; it turns red litmus to blue; It has detergent properties through the process of saponification which makes fats and grease water-miscible.
Is nano3 a solid liquid or gas?
Sodium nitrate appears as a white crystalline solid.
Is h2so4 a solid liquid or gas?
Sulfuric acid is a colorless oily liquid. It is soluble in water with release of heat. It is corrosive to metals and tissue.
Is zncl2 a solid liquid or gas?
Zinc chloride is a white crystalline solid.
Are all acids aqueous?
Most acids encountered in everyday life are aqueous solutions, or can be dissolved in water, so the Arrhenius and Brønsted–Lowry definitions are the most relevant.
How can you recognize the different forms of matter?
Key Takeaways: States of Matter A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
What are 5 characteristics of a liquid?
- liquid have a fixed volume but no fixed shape.
- liquids can be compressed. large pressure is required to compress them.
- liquids have lesser densities than solids.
- intermolecular forces of attraction is weaker than solids.
- they have considerable space between the particles.
