# data[].attributes.body
What changes occur when chemicals interact with each other?

# data[].attributes.body
What is the process of chemical reactions?
Answer=the substance break apart or combine to form one or more new substances and to creat new substances the bonds break and new bonds form.

# data[].attributes.body
Why do properties change after a chemical reaction

# data[].attributes.body
The atoms form molecules after they react with each other

no. - mrs. iyer

# data[].attributes.body
What changes and what stays the same about the chemicals after a reaction?

# data[].attributes.body
Why do particles change so drastically after chemical reactions?

# data[].attributes.body
What are the signs of a chemical reaction?

# data[].attributes.body
How do we know when two chemicals react?

# data[].attributes.body
Properties change when chemicals react because the chemical reaction changes the substance.

# data[].attributes.body
What are chemical formulas?

# data[].attributes.body
Do the properties of the chemicals change after a reaction?

# data[].attributes.body
Why and how do chemicals react
are there different types of chemical reactions

# data[].attributes.body
All of the atoms present before the reaction are still present after the reaction; none have been lost/gained

# data[].attributes.body
The atoms form molecules after they react with each other

# data[].attributes.body
When chemical reactions occur what changes and what stays the same

# data[].attributes.body
I want to know why each shell can only hold a certainty amount of electrons.

# data[].attributes.body
I see chemicals coming together to form one or two different thingys

# data[].attributes.body
Not all the atom are visible after the reaction.

# data[].attributes.body
Chemical reaction

# data[].attributes.body
The atoms become a molecule after the chemical reaction.

# data[].attributes.body
The final product is made of all the original atoms

# data[].attributes.body
All of the original atoms are present in the final molecule

# data[].attributes.body
two or more atoms are combined and they make a molecule that includes all of the atoms

# data[].attributes.body
Molecules are being formed after the reaction

# data[].attributes.body
For all the options I see multiple atoms combing, maybe through chemical reactions, to form molecules.

# data[].attributes.body
Once the atoms join they form molecules

# data[].attributes.body
The atoms for molecules after reacting with each other.

# data[].attributes.body
The original atoms are very different from the results after they are chemically combined.

are the atoms different or molecules different? - Mrs. Iyer

After reading and annotating, you have the following options.
1) Answer the question you asked if the answer was in the reading
2) Write down something you learned from the reading below.
3) If your initial thinking under "think you know" is incorrect, fix it!
4) Re-explain the visual prompt with your understanding of the reading.

One thing I learned from the reading was, A chemical reaction happens when substances break apart or combine to make new substances.

One thing I learned from the reading was, A chemical reaction happens when substances break apart or combine to make new substances.

# data[].attributes.body
In this reading I learned about exothermic and endothermic reactions. When a chemical reaction gives off energy it is exothermic, and if it takes in energy from surroundings it is endothermic.

# data[].attributes.body
I learned that endothermic reactions take energy from its surroundings and exothermic reactions give off energy to its surroundings.

# data[].attributes.body
I learned about endothermic and exothermic reactions. Endothermic reactions take place when energy is released in the area. Photosynthesis is an endothermic reaction. An exothermic reaction isn't where the energy is released out of the area. A flashlight is an exothermic reaction.

# data[].attributes.body
I learned the difference between endothermic energy and exothermic energy and how they affect our daily lives.

# data[].attributes.body
There are many different examples of chemical reactions

# data[].attributes.body
In a chemical formula, the number of each type of atom is called the subscript which is written on the bottom right of the chemical symbol

# data[].attributes.body
In the diagram, we can see the image for the chemical formula.

# data[].attributes.body
I learned that reactions can give off or take in energy

# data[].attributes.body
I learned that chemical bonds and chemical reactions are different.

# data[].attributes.body
One thing I learned is that endothermic reactions take in energy.
