Read the chemical equation. Fe2O3 + CO → Fe + CO2 If 3 moles of Fe2O3 react with 1.5 moles of CO, how many moles of each product
vfiekz [6]

Answer:- A) 1 mole of Fe and 1.5 moles of CO_2 .

Solution:- The balanced equation is:

Fe_2O_3+3CO\rightarrow 2Fe+3CO_2

From balanced equation, there is 1:3 mol ratio between Fe_2O_3 and CO,  From given data, 3 moles of  Fe_2O_3 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  Fe_2O_3 .

3molFe_2O_3(\frac{3molCO}{1molFe_2O_3})

= 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:

1.5molCO(\frac{2molFe}{3molCO})

= 1 mol Fe

1.5molCO(\frac{3molCO_2}{3molCO})

= 1.5 mol CO_2

So, the correct choice is A) 1 mole of Fe and 1.5 moles of CO_2 .

How many liters of oxygen are required to react completely with 1.2 liters of hydrogen to form water? 2H2(g) + O2(g) → 2H2(g)
Ira Lisetskai [31]

Answer:

\boxed{\text{0.60 L}}

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).

\text{Volume of O}_{2} = \text{1.20 L H}_{2}\times \dfrac{\text{1 L O}_{2}}{\text{2 L H}_{2}} = \textbf{0.60 L O}_{2}\\\\\text{You need }\boxed{\textbf{0.60 L of O}_{2}}

On-metals in group 17 on the periodic table most commonly form which type of ion?
EleoNora [17]

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.
