Answer:
Algo importante sobre el balance de una reacción química es la ley de la conservación de la masa que establece que la masa no se crea ni se destruye sólo se transforma de modo que en una reacción química la suma de la masa de los reactivos debe ser igual a la suma de la masa de los productos.
Por ejemplo: La fermentación de la glucosa es una reacción química balanceada que da como resultado etanol y dióxido de carbono.
C₆H₁₂O₆ → 2C₂H₆O +2CO₂
Calculando la masa de los reactivos y productos, se debe cumplir la ley de la conservación de la masa:
C₆H₁₂O₆= 6*12+12*1+6*16=180 g/mol
C₂H₆O= 2*12+6*1+16=46 g/mol
CO₂=12+2*16=44 g/mol
C₆H₁₂O₆ → 2C₂H₆O + 2CO₂
180 g/mol = 2*46 g/mol + 2*44 g/mol
180 g/mol = 92 g/mol + 88 g/mol
180 g/mol = 180 g/mol
Answer: Francesco Redis Experiment part 1 : The maggots were not observed in setup B and setup C because the jars were covered.
part 2 : He discovered that maggots appeared on the meat in the control jar, the jar left open. No maggots appeared in the jar covered with gauze.
Pasteur Experiment
part 1:In the pastures Experiment the microorganisms come from the air.
part 2:Louis Pasteur's pasteurization experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself.

Explanation:
Silicon (IV) oxide, commonly known as silica is a substance that majorly constitutes SAND. It has the chemical formula, SiO2, which contains a combination of silicon and oxygen.
The IUPAC name of SiO2 is Silicon IV oxide, which can also be referred to as Silicon dioxide because the structure the compound contains two (-di) oxygen atoms. Hence, based on the question, silicon(IV) oxide is the same as silicon dioxide.
