Explanation:
In a chemical reaction such as photosynthesis, substances are present before the reaction starts.
A chemical reaction is usually represented by simple chemical equations that shows the reactants and the products.
- The reactants are the compounds combining together at the beginning of the reaction.
- For photosynthesis, the reactants are carbon dioxide and water.
- The products are the results obtained from the combining reactants.
- In photosynthesis, they are glucose and oxygen gases.

Answer:
Elements that have atomic numbers from 20 to 83 are heavy elements, therefore the ratio is different. The ratio is 1.5:1, the reason for this difference is because of the repulsive force between protons: the stronger the repulsion force, the more neutrons are needed to stabilize the nuclei.
I think its 44.8 L im not that sure ;P
Answer:
A is not true.
The biosphere contains living and nonliving things.
Let me know if this helps!
Exothermic and Endothermic Reactions. The release of energy in chemical reactions occurs when the reactants have higher chemical energy than the products. ... Conversely, if the enthalpy increases during a reaction, a corresponding amount of energy must be absorbed from the surroundings.
