What is always involved in a chemical reaction?

What is always involved in a chemical reaction?

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Does melting always involve a chemical change?

Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes. On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed. The chemical change also usually involves heat, burning, or other interaction with energy.

What are the side effects of potassium chloride?

Upset stomach, nausea, vomiting, gas, or diarrhea may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Tell your doctor right away if you have any serious side effects, including: difficult/painful swallowing, feeling as if the tablet is stuck in your throat.
