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.
Answer:
His kinetic energy when he runs at that 5 m/s is 750 joules
Explanation:
The given information are;
The mass of, Lance, the runner = 60-kg
The speed by which Lance is running = 5 m/s
The kinetic energy, KE, is given by the relation;
KE = 1/2×m×v²
Where;
m = The mass = 60-kg
v = The instantaneous speed of motion = 5 m/s
The kinetic energy can be found by substituting the values of the variables in the kinetic energy equation as follows;
KE = 1/2 × 60 kg × (5 m/s)² = 750 joules
His kinetic energy when he runs at that 5 m/s is 750 joules.
