Answer: The sum of the coefficients needed to balance the combustion reaction of methane is 6.
Explanation:
Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
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.
The chemical equation for combustion of methane will be :
The coefficient foer methane is 1 , 2 for oxygen , 1 for carbon dioxide and 2 for water. The sum is 6.
Silver-109 has a mass of 109 amu. It is one of the isotopes of the silver atm.
<h3>What are isotopes?</h3>The term isotopes has to do with the atoms of the same element that has the same atomic number but different mass numbers. This implies that the isotopes that we have do have the same number of protons but they do not have the same number of neutrons and the fact that they differ in the number of neutrons implies that would have the same chemical property.
We can see from the question that there are two isotopes of silver and tehse isotopes of silver have been identified as silver-107 and silver-109. The isotopes do have the same mass and not the same number of protons.
The percentage abundance of the two isotopes are not the same which means that one is more than the other. We can now see that the mass of the silver 109 in amu is 109 amu.
