Answer:
It is a chemical reaction because total mass remain unchanged.
Explanation:
A chemical reaction is represented by a chemical equation which show the reactant and products. Reactants are written on left side of arrow while products are written on right side. The number of atoms are remain same however arrangement of atoms is different on both side.
For example:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen. The number of atoms are same on both side however arrangement of atoms is different.
While in case of nuclear reaction small change in mass take place.
Answer: it holds two atoms together in a molecule. During a chemi- cal reaction, some of the bonds in the original molecule break. New bonds form to produce a new substance.
Explanation:
0 degrees Celsius, 32 degrees Fahrenheit. So the answer is a
