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!
Answer:
Mass of ammonia = 34 g
Explanation:
Given data:
Number of molecules of ammonia = 1.204 × 10²⁴
Mass of ammonia = ?
Solution:
First of all we will calculate the number of moles.
one mole of ammonia = 6.022 × 10²³ molecules
n = 1 mole/6.022 × 10²³ molecules × 1.204 × 10²⁴ molecules
Number of moles = 2 mol
Mass of ammonia:
Number of moles = Mass / molar mass
Mass of ammonia = number of moles × molar mass
Mass of ammonia = 2 mol × 17 g/mol
Mass of ammonia = 34 g
Answer:
H-O-H water
Explanation:
hydrogen bonds occur when hydrogen atom undergoes dipole-dipole attraction to an electronegative atom such as hydrogen and fluorine, oxygen or nitrogen
