Answer: Adding Hydrogen Gas

Explanation:

The Reduction Reaction that occurs during the refinement of Iron Ore is as follows:

Fe_3O_4 + H_2  -> 3FeO + H_2O\\\\FeO + H_2   -> Fe + H_2O

Since Hydrogen Gas is a reactant in the equation with Iron ore , adding more hydrogen gas will shift the reaction toward the right side, increase the amount of  refined iron produced.

Answer:

The correct answer is increase in temperature.

Explanation:

During heating of the iron ore with the hydrogen gas at high temperature, the production of water and element iron takes place. High temperature is one of the essential condition for this chemical reaction to take place.  

The more the temperature is, the more will be the amount of the production of iron, this is due to the presence of high temperature, which is one of the mediating force for the production of iron. Therefore, an increase in temperature will produce a greater amount of iron.

If mercury (Hg) and oxygen (O2) were reacted to form mercury oxide how many molecules of each reactant and product would be need
dimulka [17.4K]
In order to get HgO you would need 2Hg+1O2=2HgO. Since oxygen is diatomic you need two when it stands alone causing you to need two mercuries to balance out the reactants and the product I hope this helps

Explain how scientific observations led to the development of, and changes to, the periodic table.
Musya8 [376]
The following are scientific observations which led to development and changes of periodic table: Dmitri Mendeleev is the first periodic table organized 63 known element according to its properties, organized into rows and columns and inscribed name, mass and chemical properties on each element. Julius Lothar Meyer who independently worked in Germany with Ernest Rutherford. They experimented with 38 metals and found out that the positive charge of each element nucleus increased by one from element to element and organized the periodic table that tip to modern explanation of atomic number and the recognition of atomic number was the basis for organization of periodic table.
