What Are Clues That A Chemical Reaction That A Chemical Reaction May Have Taken Place?
formation of a solid and release of heat. apex
Do you think a chemical reaction has taken place Can you explain your reasoning behind your conclusion?
Yes, a chemical reaction has likely taken place if there is a change in the chemical composition of the substances involved. This can be observed through the formation of new substances, changes in color, temperature, or the release of gas. These are all indicators that a chemical reaction has occurred.
How can you tell if a chemical reaction has taken place when a hot air balloon flies?
When a hot air balloon flies, the chemical reaction that occurs is the heating of the air inside the balloon, causing it to expand and become less dense than the surrounding air. This creates lift, allowing the balloon to rise. You can confirm that a chemical reaction has taken place by observing the change in volume and buoyancy of the air inside the balloon as it heats up.
How can you determine if a chemical reaction has occurred?
A chemical reaction can be determined by observing changes in physical properties, such as color, temperature, gas production, or formation of a precipitate. Additionally, chemical tests or instruments can be used to analyze the substances involved before and after the reaction to confirm a chemical change has taken place.
What indicators definitely show that a chemical reaction has taken place?
Some indicators that show a chemical reaction has taken place include the formation of a gas, a color change, the production of heat or light, or the formation of a precipitate (a solid formed from two liquids mixing together).

What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.

What are four clues that a chemical change has taken place?

Do you think a chemical reaction has taken place Can you explain your reasoning behind your conclusion?

This can be observed through the formation of new substances, changes in color, temperature, or the release of gas. These are all indicators that a chemical reaction has occurred.
What changes gives NO evidence that a chemical reaction has taken place?
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
What evidence that a chemical reaction has taken place would a living thing show?
work
What chemical reactions come with a fire what changes has taken place?
A fire is an oxidation reaction.
Which is indicated if a gas forms when two or more substances are mixed?
a chemical reaction has taken place.

What term is These are the substances that are present after the reaction has taken place?
The term is "products." In a chemical reaction, reactants react to form products. Products are the substances that are present after the reaction has taken place.
What are clues that a chemical reaction has taken place A Formation of a gas B Constant temperature C Steam D Change in color?
A) Formation of a gas: Bubbles or fizzing can indicate the release of a gas during a chemical reaction. C) Steam: The presence of steam may indicate that water is being formed as a product of the reaction. D) Change in color: A noticeable change in color of the substances involved can suggest a chemical reaction has occurred.
