Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g
Where v is the volume(in L) and t is the temperature(in °K)
Answer: Isotope Oxygen 18 will remain the same before and after the reaction because the amount of neutrons are the same in a isotope
Explanation:
Isotopes 18-17 and 16 are the most stable in earth. Keep in mind that a Isotope is an atom that has equal amount of protons and electrons but neutrons ( as you can see in the imagine below) . That is why, an isotope like oxygen 18 will remain the same in a chemical reaction, because there is only a electron transfer when doing a new molecule.
