Answer:
chlorine is therefore an anion
Answer:
1) evolution of gas
2) evolution of heat
Explanation:
In this reaction, glucose is broken down into its constituents; carbon dioxide and water. The question is to decipher indicators of a chemical reaction from the equation.
If we look at the equation carefully, we will notice that a gas was evolved (CO2). The evolution of a gas indicates that a chemical reaction must have taken place. Secondly, energy is given off as heat. This is another indication that a chemical reaction has taken place.
The last set which is n=4 l=3 m=3 is a valid set
Answer:
Bonds between atoms are broken/ or new bonds are formed
Explanation:
Due to chemical changes.
D. The energy released or absorbed during the reaction
