A chemical reaction occurs when substances change. Photosynthesis is the process by which plants produce food.
1) A chemical reaction is a process by which substances can be changed into other substances. Hence, in a chemical reaction, new substances are formed.
2) Photosynthesis is the process by which plants produce food using carbon dioxide and water in the process of sunlight and chlorophyll. Glucose is produced during photosynthesis and the energy produced and stored as starch.
3) Valence electrons show the kind of bond that an atom can form. Reaction between two atoms that have many valence electrons is most likely covalent. An ionic bond is formed between an atom that has few valence electrons and an atom that has many valence electrons.
4) A carbohydrate is a compound that comprises of hydrogen and oxygen in a ratio of 2:1. The compound that is a carbohydrate is C3H6O3.
5) Rocks contain iron. Iron oxides form when cyanobacteria produce oxygen via photosynthesis.

A.) The reaction is Exothermic
Answer:
I think it's 6 moles are produced
Answer:In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged. Chemical changes, on the other hand, rearrange the atoms of matter in new combinations, resulting in matter with new physical and chemical properties.
Explanation:
easy
Answer:
since it has lower mass. the force acting on it results in larger acceleration.
