What else can I help you with?
What is observed when copper sulphatepentahydrate is exposed to ammonia gas?
A chemical reaction is observed.
How do you decide whether an observed property of matter is a chemical property?
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
Can neutralize a base is physical property or chemical property?
This is a chemical property because it can only be observed in a chemical reaction.
How do you decide whether an observed property of matter is a physical property?
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
How is burning an example of a chemical property?
Burning is an example of a chemical property because it can only be observed during a chemical reaction called combustion.
What properties can be observed during a chemical reaction?
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 chemiluminescence -formation of new compounds
Chemical properties observed only when a substance undergoes a chemical change a true bfalse?
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
What defines an exothermic reaction?
A reaction that produces heat
What change in color is observed when silver chloride is left exposed to sunlight. What type of chemical reaction is this?
This is a photochemical reaction of decomposition: silver (black) is released.
What is a condition that is observed and measured in an experiment?
One example of a condition that is observed and measured in an experiment is the temperature of a solution in a chemical reaction. Researchers can measure the temperature at different time points to investigate how it changes during the reaction, providing insights into the reaction kinetics and thermodynamics.
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.
What kind of mixture have you observed?
Two or more chemical substances, mixed without a chemical reaction form a mixture; examples: wine, asphalt, juice, air.
