In particles physics, the weak interaction (the weak force or weak nuclear force) is one of the four known fundamentals interactions of nature, alongside the strong interaction, electromagnetism, and gravitation.
This is based on my research, hope it helped :) <span />
The balanced equation for the above reaction is as follows;
2H₂ + O₂ --> 2H₂O
stoichiometry of O₂ to H₂O is 1:2
number of O₂ moles reacted - 40.3 g / 32 g/mol = 1.26 mol
according to molar ratio
number of water moles produced = 2 x number of O₂ moles reacted
number of water moles formed - 1.26 x 2 = 2.52 mol
mass of water produced = 2.52 mol x 18 g/mol = 45.4 g
45.4 g of water produced
Answer:
Radius of the bubble reaches the surface of the water = 4.68 cm
Explanation:
We know Ideal gas equation PV = nRT
Since amount of gas and temperature remains constant
so p₁v₁ = p₂v₂
Volume of Spherical bubble with a radius of 3.0 cm
⇒ v₁= 
⇒ v₁ = x 3.14 x 
Pressure at the depth p₁ = 4 atm
Volume of bubble when it reaches the surface of water =
Pressure p₂ = 1 atm
p₁v₁ = p₂v₂
⇒ 4 x x 3.14 x = 1 x
⇒ r = 4.68 cm
That statement is true. Hope I was of assistance :)
Addition of pure water does not change pH of a solution because pure water has neutral pH.
<h3>Why the pH does not change when pure water is added?</h3>
Even though you continue to add pure water into a substance, the acidity or alkalinity of substance still remains the same to that of substance because pure water has neutral pH which can't change the acidity or alkalinity of a solution.
So we can conclude that addition of pure water does not change pH of a solution because pure water has neutral pH.
