The thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production is an industrial production of nano-sized titanium dioxide (TiO2).
<h3>What is thermodynamics?</h3>
Thermodynamics is defined as the change in the energy of system that brings about work in that system.
The leaching of ilmenite which is a titanium-iron oxide mineral with HCl can lead to the production of titanium dioxide (TiO2).
The use of thermodynamics in this process controls the heat and energy of the leaching system leading to a better yield of final products.

<h3><u>Answer</u>;</h3>
= 1.44 L
<h3><u>Explanation</u>;</h3>
Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.
Mathematically;
<em>P α 1/V</em>
<em>PV =constant </em>
<em>Thus, P1V1 = P2V2 </em>
<em>P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm</em>
<em>V2 = P1V1/P2</em>
<em> = (1× 3.6)/2.5 </em>
<em> = </em><u><em>1.44 L</em></u>
Answer:
C. 65.5 g PF3 x (1 mole / 87.97 g PF3)
Explanation:
Dimensional analysis can be used to find the amount of moles in 65.5 grams of PF3 gas.
First we would need to determine relevant conversions.
We would need to find the molar mass of PF3 which is already given ( 87.97 g / mol )
So 1 mole of PF3 = 87.97g
From there we can create the dimensional analysis table which will look something like the attached image.
This table correspond with answer choice C.
<u>Reasons </u><u>it's </u><u>not </u><u>the </u><u>other </u><u>answer </u><u>choices</u><u>.</u>
It wouldn't be A because the units must cancel out and they don't as grams is being multiplied by grams
It would be B because it doesn't use correct units.
There are not 87.97 moles in 1 gram of PF3. There are 87.97 grams in 1 mole of PF3
