O2 is the limited reactant
Answer:
Question 1: Conversion of SO3 into concentrated sulphuric acid.
Question 2: It is necessary to provide heat to the reaction mixture.
Explanation:
Question 1: The first thing you do is dissolve the sulfur trioxide in concentrated sulphuric acid, which produces disulfuric acid. It cannot be carried out by a simple reaction of sulfur trioxide with water. Disulfuric acid does react with water safely, breaking down into 97-99% concentrated sulfuric acid.
Question 2: One reason is due to kinetics (low temperatures will cause the equilibrium to be displaced, but the reaction will be slower) and the other is due to the performance of the catalyst. Thus, the temperature used must be high, since the catalyst works well in this way, and produces a sufficiently high proportion of SO3 in the equilibrium mixture and at a sufficiently high speed.
Have a nice day!
The balanced reaction is:
<span>2Al (s) + 3Fe(NO3)2 (aq) = 3Fe (s) + 2Al(NO3)3 (aq)
</span>
We are given the amount of <span>iron (II) nitrate solution with its purity. This will be the starting point of our calculation.
265 (.845) gram </span>iron (II) nitrate (1 mol Fe(NO3)2 / 179.85 g Fe(NO3)2) ( 3 mol Fe / 3 mol <span>Fe(NO3)2) (55.85 g Fe / 1 mol Fe) = 69.54 g Fe</span>
The characteristics of an Arrhenius acid was the acid donates H+ when it is in the aqueous solution, whether the solution is acid or base. If the solution is a acid, then be H+ builds up and increase its thing. The pH level for acid solution is the scale from 1-6. Even though the ph scale is lower than the base, the color also varies. It also applies to the base, too.
