Answer
There is a colour change, At least 1 new substance is created, An energy change can be measured, Gas is released, Compounds are broken up or formed
Explanation
## Step 1:A chemical reaction involves the transformation of substances into new ones, often accompanied by observable changes.## Step 2:A "colour change" is a key feature of a chemical reaction. This occurs when the reactants transform into products with different colors.## Step 3:The creation of at least one new substance is a fundamental aspect of a chemical reaction. This is the essence of chemical change.## Step 4:An "energy change" can be measured during a chemical reaction. This can be in the form of heat, light, or other energy forms, indicating either an exothermic or endothermic process.## Step 5:The release of gas is another observable feature of some chemical reactions. This can be seen when bubbles form or gas is emitted.## Step 6:The breaking up or formation of compounds is intrinsic to chemical reactions. Reactants may break down into simpler substances or combine to form more complex compounds.#
