Which observation does not indicate that a chemical reaction has occured?
A change in state, such as boiling or melting, does not always indicate a chemical reaction has occurred. It could be a physical change.
What shows the relationship between the reactants and products in a chemical reaction?
the coefficients of a balanced reaction
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.
What shows changes that take place during a chemical reaction?
Evidence of a chemical reaction includes color change, formation of precipitate, evolution of gas, and changes in temperature. These changes can indicate that new substances are being formed through the rearrangement of atoms.
What are the 5 signs of a chemical changing?
Five signs of Chemical changes are... 1. light is emitted 2. sound 3. new smell 4. bubbles 5. changes in density There are more than five signs, but theses are the ones I can think of right now.
Is ch3 electron donating or withdrawing in a chemical reaction?
In a chemical reaction, CH3 is electron donating.
Are carbonyls electron donating or withdrawing in a chemical reaction?
Carbonyls are electron withdrawing in a chemical reaction.
How many electrons does sodium lose in a chemical reaction?
Sodium typically loses 1 electron in a chemical reaction.
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
What in general terms does a chemical equation indicate?
A chemical equation is the representation of a chemical reaction.
What does it indicate when the value of G is negative in a chemical reaction?
When the value of G is negative in a chemical reaction, it indicates that the reaction is spontaneous and releases energy.
In a chemical reaction what subatomic particles are being changed?
the electron
Which arrow is used to indicate a reverse or backward reaction in a chemical equation?
The arrow that is used to indicate a reverse or backward reaction in a chemical equation is called a double-headed arrow.
Which sub-atomic particle creates chemical reaction?
Proton and Neutron do not take part in chemical reaction. Only electron takes part in the reaction.
What does a negative enthalpy indicate in a chemical reaction?
A negative enthalpy in a chemical reaction indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings.
A solid that forms from solutions during a chemical reaction is called A?
precipitate
Concise representation of a chemical reaction?
type of electron in outer shell
