What is the evidence that a chemical reaction took place when silver nitrate was mixed with ammonium chloride?
The evidence that a chemical reaction took place when silver nitrate was mixed with ammonium chloride is the formation of a white precipitate of silver chloride. This indicates that a chemical reaction occurred between the silver ions from silver nitrate and the chloride ions from ammonium chloride, resulting in the insoluble silver chloride. Additionally, the solution may turn cloudy or there may be a color change, further supporting the occurrence of a chemical reaction.
If you are trying to decide whether a chemical reaction does or does not take place when two substances are mixed what kind of evidence will you look for?
To determine if a chemical reaction takes place when two substances are mixed, you can look for evidence such as color change, formation of precipitate, gas production, change in temperature, and the evolution of light or sound. These observable changes indicate a chemical transformation has occurred.
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
What evidence do you have that a chemical reaction took place?
Evidence of a chemical reaction includes the formation of a new substance with different properties, changes in color, the release of gas or heat, or the formation of a precipitate. Additionally, changes in mass due to the rearrangement of atoms in the reactants can also indicate a chemical reaction has occurred.
When two white compounds are mixed in a solution a yellow solid forms What kind of reation has taken place?
A chemical reaction that has taken place is likely a precipitation reaction. The formation of a yellow solid suggests the creation of a new compound that is insoluble in the solution and precipitates out.
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.
When baking soda is mixed with vinegar which type of reaction has taken place?
its a chemical reaction

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.

These observable changes indicate a chemical transformation has occurred.
Is cement recyclable?
No, cement is not recyclable.Because when it is mixed with water chemical reaction takes place and gains strength and hardens.The hardened cement cannot be used as a recycled one because no chemical reaction takes place when mixed with water.
What evidence that a chemical reaction has taken place would a living thing show?
work
What evidence would one observe to indicate that a double displacement reaction has occurred?
Evidence of a double displacement reaction includes the formation of a precipitate (solid) when two solutions are mixed, a color change, or the formation of a gas or a distinct odor. Observing any of these changes typically indicates that a chemical reaction has taken place.
Which is indicated if a gas forms when two or more substances are mixed?
a chemical reaction has taken place.
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
Bubbling present during a chemical reaction is evidence of what?
Bubbling present during a chemical reaction is evidence of a gas being produced. The formation of gas bubbles indicates that a chemical change is taking place, often as a result of a reaction between two or more substances.
How is a precipitate evidence for a chemical reaction?
A precipitate forms when two aqueous solutions react to produce an insoluble solid. The formation of a precipitate indicates that a chemical reaction has occurred, as the reactants have undergone a change in chemical composition to produce a new substance with different physical properties. This is observable evidence of a chemical change taking place.
