Well when the sun makes water dissaper thats usually evaporation.
The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically nothing has changed. The plant still looks the sam changes occur internally these internal changes are chemical in nature.
Well, according to the law of conservation of mass, the total mass of the reacting atoms must equal the total mass of the final rearranged products produced through the reaction. Assuming that both products are the only products produced, it would constitute the total matter produced, and since each product has a mass of 25 grams each. The total would be 50 grams. Thus the total mass of the reactants also would need to be 50 grams, as no matter is lost in a chemical reaction.
Answer:
boron compound - known as Borax
Explanation:
The molecular formula iust is how many total number of atoms of each type are present in a molecule.
Have a close look at the structure, the large sized black atoms shown here are Carbons. Count the number of carbons, total of 5 carbons.
The smaller ones are hydrogens. Count the hydrogens they are 12.
The symbol for Carbon is C and Hydrogen is H. The molecular formula is thus C5H12.
The iupac name is Pentane
