Answer:
I am sure it is D or C. have a nice day
Can i get a list of possible answers plz?
The given balanced reaction is,
The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.
The mole ratios of different products and reactants will be:
So the mole ratio comparing iron (Fe) and oxygen gas (
) is
4 : 3
B. the periodic law
Explanation:
The periodic law was not explained by the Dalton's atomic theory.
The periodic law was first postulated by Dimitry Mendeleef and Lothar Meyer around 1869 where they independently arrived at the periodic table or chart.
- The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- The modern periodic law was restated by Henry Moseley in the early 1900s. He changed the basis of the law to atomic number.
- The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".
The laws of conservation of mass, multiple proportions and definite proportions are all explained by the Dalton's atomic theory.

The definition of a common ion as it applies to Le Chatelier's principle is an ion that is present in an equilibrium system and a compound added to the system. This is the case since in Le Chatelier's principle, it is based on an equilibrium system and where the reaction shifts to the left or to the right; towards the products or the reactants side.
