What specific property would litmus paper indicate?
It would indicate whether something is an acid or a base.
Is hydrochloric acid in stomach acid alkali or neutral?
Hydrochloric acid in stomach acid is an acidic substance, not alkaline or neutral. Stomach acid has a low pH level, usually around 1-3, due to the presence of hydrochloric acid, which aids in digestion by breaking down food and killing bacteria.
What is are four things that indicate that a chemical change probably happened?
Four things that indicate a chemical change probably happened include color change, formation of a precipitate, evolution of gas, and change in temperature. These signs suggest that a new substance with different chemical properties has been formed.
How do you show precipitate in reaction?
Sometimes it is indicated by a subscript "s" in parentheses to indicate a solid. Other times an arrow pointing downward is placed next to the compound that forms the precipitate to indicate that it came out of solution.
What are four things that indicate that a chemical change may have taken place?
Change in color: If the substance changes color during a reaction, it may indicate a chemical change. Formation of gas: Production of gas bubbles, fizzing, or bubbling is a sign of a chemical change. Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
What type of change does precipitate indicate?
The formation of a precipitate typically indicates a chemical change, as it involves the creation of a new, insoluble solid substance from the mixing of two solutions. This reaction often results in the release or absorption of energy, indicating a change in the chemical properties of the substances involved.

What would happen if you ate hydrochloric acid?
It would very much depend on the strength of the acid, which you do not indicate. Your stomach is already full of hydrochloric.

What are four things that indicate that a chemical change probably happened?
Production of gas: If there is a sudden release of gas, bubbling, or fizzing, it may indicate a chemical change. Formation of a precipitate: A solid substance forming in a solution can indicate a chemical change has occurred. Color change: A visible change in color of the substance can be a sign of a chemical reaction. Change in temperature: A noticeable temperature change, either an increase or decrease, can be an indicator of a chemical change taking place.
When two substances are mixed they might form a new substance What would indicate that a new substance has been formed?
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence - formation of new compounds
What would indicate that a chemical change might be occurring?
Two solutions are mixed and a solid begins to appear
