Answer:
5 mol.
Explanation:
Equation of the reaction
2SO2 + 2H2O + O2 --> 2H2SO4
By stoichiometry, 2 moles of SO2 reacted with 2 moles of water and 1 mole of O2 to give 2 mole of sulphuric acid.
Number of moles:
5.0 mol SO2
4.0 mol O2
20.0 mol H2O
Calculating the limiting reagent,
5 mol of SO2 * 1 mol of O2/2 mol of SO2
= 2.5 mol of O2(4 mol of O2 is present)
5 mol of SO2 * 2 mol of H2O/2 mol of SO2
= 5 mol of H2O(20 mol of H2O)
SO2 is the limiting reagent.
Therefore, number of moles of H2SO4 = 5 mol of SO2 * 2 mol of H2SO4/2 mol of SO2
= 5 mol of H2SO4.
Hey there!
Kinetic energy means that something is in motion.
Therefore, the answer would be B. Bird in flight because it’s the only choice that suggests is moving.
Hope this helps!
God bless ❤️

Answer:
A. 3.2L of NO
B. 4.8L of H2O
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
4NH3 + 5O2 —> 4NO + 6H2O
A. Determination of the litres of NO produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 4L of NO.
Therefore, 4L of O2 will produce = (4x4)/5 = 3.2L of NO.
B. Determination of the litres of H2O produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 6L of H2O.
Therefore, 4L of O2 will produce = (4x6)/5 = 4.8L of H2O
