Answer:- A) 1 mole of Fe and 1.5 moles of
.
Solution:- The balanced equation is:

From balanced equation, there is 1:3 mol ratio between
and CO, From given data, 3 moles of
and 1.5 moles of CO are taken for the reaction. CO is the limiting reactant as it's moles are less than the other reactant and which is also clear from the mole ratio. We could do the calculations also to support this. Let's calculate the moles of CO required to react completely with given 3 moles of
.

= 9 mol CO
So, from calculations, 9 moles of CO are required to react completely with 3 moles of Iron(III)oxide but only 1.5 moles of CO are available. Hence, CO is the limiting reactant and the product moles are calculated from this as:

= 1 mol Fe

= 1.5 mol 
So, the correct choice is A) 1 mole of Fe and 1.5 moles of
.

Answer:
Explanation:
We can use Gay-Lussac's Law of Combining Volumes to solve this problem.
Gases at the same temperature and pressure react in the same ratios as their coefficients in the balanced equation.
1. Write the chemical equation.
Ratio: 2 L 1 L
2H₂ + O₂ → 2H₂O
V/L: 1.2
2. Calculate the volume of O₂.
According to Gay-Lussac, 1 L of O₂ forms from 2 L of H₂.
Then, the conversion factor is (1 L O₂/2 L H₂).

Answer:
1- ions
Explanation:
Non-metals in group 17 on the periodic table most commonly forms -1 ions with other chemical species.
This is because of their atomic structure
Group 17 is made up of halogens which are fluorine, chlorine, bromine, iodine and astatine.
Because each of the elements has seven electrons in the outer shells of their atoms which implies that they lack one electron to become an octet, the elements are all univalent and also acceptors of electrons.
