Answer:
Explanation:
Given data:
Mass of water used = 4.05 g
Mass of each product produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 4.05 g/ 18 g/mol
Number of moles = 0.225 mol
Now we will compare the moles of water with hydrogen and oxygen.
H₂O : H₂
2 : 2
0.225 : 0.225
H₂O : O₂
2 : 1
0.225 : 1/2×0.225 = 0.113 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.225 × 2 g/mol
Mass = 0.45 g
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.113 mol × 32 g/mol
Mass = 3.616 g
Well, technically it would have a pH reading and or measurement of 0. As a ph of 1 would represent that there are hydrogen ions, no matter how less present in the solution, since pH is a measure of Hydrogen ions present in a solution, a pH value of 0 would mean virtually no protons, hydrogen ions.
The De Broglie wavelength of the muon is calculated to be 4.13 × 10^10 m
We have the following information;
mass of the muon (m)= 206.8 × 9.11 × 10^-31 Kg = 1.88 × 10^-28 Kg
Plank's constant(h) = 6.6 × 10^-34 Js
Velocity of the muon(v) = 8.50×10^5 cm/s or 8500 m/s
From;
λ = h/mv
λ = 6.6 × 10^-34/1.88 × 10^-28 × 8500
λ = 6.6 × 10^-34/1.598 × 10^-24
λ = 4.13 × 10^10 m
