Answer:
Equal number of atoms of each gas in each container
Explanation:
When the valves opened, the two contaienrs become one and the gases beging to mix by diffusion. This phenomenom is produced by the differeces of concentration of a gas between two points of the container.
The gases will continue diffunding util their concentration in both containers are equal.
If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed.
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

Answer: A) 67.1 moles
Explanation:
The balanced reaction is :


To calculate the moles, we use the equation:

According to stoichiometry;
2 moles of iron is produced by 3 moles of carbon monoxide
89.3 moles of iron is produced by=
moles of carbon monoxide
2 moles of carbon monoxide is produced by = 1 mole of oxygen
Thus 134 moles of carbon monoxide is produced by =
moles of oxygen
