When hydrogen sulfide gas (H2S) reacts with oxygen gas (O2), they form solid sulfur (S).
There are many elements which are gases at room temperature, including hydrogen, helium, nitrogen, oxygen, fluorine, chlorine and all noble gases.
The two elements that are liquid at standard temperature and pressure are Mercury (Hg) and bromine (Br.)

When two liquids react to form a solid it is called an?
When two liquids react to form a solid, it is called a precipitation reaction. This occurs when a solid substance, known as a precipitate, forms as a result of the reaction between the two liquids.
A solid product that may form when chemicals in two liquids react?
A precipitate is a solid product that may form when chemicals in two liquids react. It is insoluble and falls out of solution as a result of the chemical reaction.
What would happen to the volume of HCL if added to the ammonia gas?
When hydrochloric acid (HCl) is added to ammonia gas (NH3), the two substances will react to form ammonium chloride (NH4Cl) which is a solid compound. This reaction will result in a decrease in the overall volume of the system as the gases combine to form a solid precipitate.
What happens when a solid is mixed with a solid?
When two solids are mixed together, they form a mixture of the two substances. Depending on the properties of the solids, they may mix evenly or remain separate. If the two solids react chemically, a new compound may form.
In what type of reaction are precipitates formed?
Precipitates are formed in double displacement reactions, where two aqueous solutions react to form an insoluble solid compound. This solid then precipitates out of solution.
When two liquids react to form a solid it is called an?
When two liquids react to form a solid, it is called a precipitation reaction. This occurs when a solid substance, known as a precipitate, forms as a result of the reaction between the two liquids.
A solid product that may form when chemicals in two liquids react?
A precipitate is a solid product that may form when chemicals in two liquids react. It is insoluble and falls out of solution as a result of the chemical reaction.
Can a solid react to a liquid?
Yes, a solid can react with a liquid through processes like dissolution, precipitation, and neutralization. In dissolution, the solid dissolves in the liquid to form a solution. In precipitation, a solid forms from the reaction of two dissolved substances. In neutralization, an acid and a base react to form water and a salt.
Why does a solid form if you mix two liquids together?
A solid can form when two liquids are mixed together if a chemical reaction occurs that produces a precipitate, a solid substance that forms from the reaction. This can happen when two liquids react to form a new solid compound that is insoluble in the liquid mixture.
What would happen to the volume of HCL if added to the ammonia gas?
When hydrochloric acid (HCl) is added to ammonia gas (NH3), the two substances will react to form ammonium chloride (NH4Cl) which is a solid compound. This reaction will result in a decrease in the overall volume of the system as the gases combine to form a solid precipitate.
What type of chemical reaction takes place when ammonia and hydrogen chloride gases are mixed and write a chemical equation of this?
NH3(g) + HCl(g) ==> NH4Cl(s). This type of reaction is called "synthesis". The two gases react to form a solid ammonium chloride salt.
Which are the 2 colorless gases that combine to form a colourless liquid?
The two colorless gases that combine to form a colorless liquid are hydrogen gas (H2) and oxygen gas (O2), which react to form liquid water (H2O) through a chemical reaction.
What happens when two noble gases are combined?
When two noble gases are combined, they tend to form a stable non-reactive mixture due to their full outer electron shells, which makes them very unlikely to react with other elements. This makes noble gas compounds very rare under normal conditions.
What are two gases that are unlikely to react with steel?
Argon and Helium. Being inert gasses, they do not react with anything.
What happens when a solid is mixed with a solid?
When two solids are mixed together, they form a mixture of the two substances. Depending on the properties of the solids, they may mix evenly or remain separate. If the two solids react chemically, a new compound may form.
What is precipitation reaction reaction?
A precipitation reaction is one in which two solutions react to form an insoluble solid called a precipitate and a precipitate is an insoluble solid which is formed on mixing certain solutions.
Is a precipitate a phsical change?
Yes, a precipitate is a physical change. It occurs when two solutions react to form a solid that settles out of the solution. This is a reversible change as the solid can be redissolved back into the solution.
