What is an effect of a chemical change?
A chemical change is when substances become new substances that cant go back to its physical properties (the ability to participate in chemical reactions). Chemical changes usually absorb or let off heat. Often, a second chemical change is needed to reverse an initial chemical change. A chemical change is when substances become new substances that have different chemical properties (the ability to participate in chemical reactions). Chemical changes usually absorb or let off heat. Often, a second chemical change is needed to reverse an initial chemical change.
Is a rotting bread a chemical change?
Yes, the rotting of bread is considered a chemical change because it involves the breakdown of the bread's molecules into simpler compounds through chemical reactions. This transformation is irreversible and results in the formation of new substances.
What is substance that undergo both chemical and physical changes?
Water is a common substance that undergoes both chemical and physical changes. Physical changes can include changes in state, such as melting or freezing, while chemical changes involve the formation of new substances through a chemical reaction, such as rusting or burning.
How does a chemical change affect the composition of matter?
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
What sentence has the word chemical reaction?
A chemical change is a resultant change of a combination of a couple different substances that become a new substance. A sentence with this is: "Its particles changed due to it undergoing a chemical change."
Why is grape juice turning to wine a chemical change?
It is a chemical change because it can not be reversed
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.
Why is it important to know chemical properties of substances?
Yes!
How do WE know that caramelizing sugar is a chemical change?
Caramelizing sugar involves breaking down the sugar molecules through heat, which creates new compounds that have different properties than the original sugar. This is a chemical change because new substances are formed that cannot be easily reversed back into the original sugar.
When a chemical change occurs what do you know about the amount of matter in the new substances What is this known as?
In a chemical change, the amount of matter in the new substances remains constant. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged.
