Answer: Option (b) is the correct answer.
Explanation:
A spontaneous reaction is defined as the process which tends to occur on its own. It does not require any external factor or force in order to start itself.
For example, when we dissolve KCl in water then potassium chloride being ionic in nature will dissolve on its own. Hence, it will be a spontaneous process.
And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.
Thus, we can conclude that the statement it does not require any external action to begin, is true about a spontaneous process.
Answer:
5.46
Explanation:
From the question,
pH this can be defined as the acidity or alkalinity of a solution.
The expression for pH is given as
pH = -log(H⁺)...................... Equation 1
Where H⁺ = Hydrogen ion of HCL
Given: H⁺ = 3.5×10⁻⁶ M
Substitite this value into equation 1
pH = -log(3.5×10⁻⁶)
pH = 5.46
Hence the pH of HCl is 5.46
Answer:
methanol is a carbon compound which is formed by covalent bonding .
If they move at the same speed than heavy one will have more inertia.
