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.


Signs of chemical change?

Signs of a chemical change include the formation of a precipitate, a color change, the release of gas (bubbles), and a temperature change (exothermic or endothermic). These changes indicate that new substances are being formed with different chemical properties than the original substances.


Why does this indicate that a chemical reaction might have occurred?

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


What observations does not indicate that a chemical change has occurred a. change of state b. formation of a precipitate c. absorption of energy d. release of a gas?

Change of state does not necessarily indicate a chemical change. It could be a physical change, such as melting or freezing, where the substance remains the same chemically. On the other hand, the formation of a precipitate, absorption of energy, and release of a gas are all indicators that a chemical change has occurred.


What are some evidences that a chemical change occur?

Some evidence that a chemical change has occurred include the formation of a precipitate, a change in color or odor, the production of gas bubbles, or a change in temperature. These observable changes indicate that a new substance has been formed with different chemical properties from the original substances.

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.

What are the four occurrences indicate a chemical reaction has occurred?

A chemical reaction can result in any or all of the following: - a change in temperature (up or down) - a change in color - a smell that wasn't there before - the formation of bubbles (indicating the production of a gas) - the formation of a precipitate


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.


Can you list three kinds of changes that indicate a chemical reaction has taken place?

Some signs that a chemical change has taken place is that a gas can be produced, the temperature can change, and a substance disappears. Other signs are that a solid is formed, the color changes, and a new odor is produced.
