Answer:
For each balanced reaction, indicate the total number of atoms in the table below. Reaction. Total Number of Atoms. Reactant Side 1 Product Side. (Left).
Explanation:
First, we divide the number of atoms of silicon given in the problem above by Avogadro's number 6.6022 x10^23. This will give us the number of moles of silicon. Then, we multiply the number of moles by the molar mass of silicon.
number of moles = (3.6 x 10^20 atoms/6.022x10^23 atoms) = 5.97x10^-4 moles
Then, multiplying by the molar mass
(5.97x10^-4 moles)(28.0855 g/mol) = 0.017 grams

Answer:
"Gustavo is having an operation in the area across his abdomen and must follow the instructions after the operation is complete."
Explanation:
As shown in the question above, Gustavo underwent a transabdominal operation, ie Gustavo underwent surgery on the abdomen. As the abdomen is a delicate and widely used region of the human body, Gustavo's doctor provided some instructions that Gustavo should follow during the postoperative period that would ensure that he had a good recovery and no further health problems. Based on this, we can conclude that the statement that best explains this scenario is "Gustavo is having an operation on the abdomen area and should follow the instructions after the operation is completed."
<span>Observing a property of a substance can be done through experiments. Most of these experiments are done by a chemical reaction. A chemical reaction involves two substances interacting with each other. However, not all property of a substance can only be observed through a reaction. Like melting experiment, freezing point determination and boiling point determination, only heat is added or is removed to the substance in order to see that certain property.</span>
