<span>The rate of crystallizing is equivalent to the rate of dissolving.</span>
The Richter scale is logarithmic, meaning that for every whole number increase on the Richter scale, the 'power' of the earthquake increases by a factor of 10.
If there's something necessary on the pic, I'm sorry but I can't access it where I am right now.
Answer: -1835 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to Hess’s law, the chemical equation can be treated as algebraic expressions and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
(1)
(2)
Net chemical equation:
(3)
Multiplying equation (1) by 4, and reversing we get
(4)
Adding (2) and (4)
Thus enthaply change for the reaction is -1835 kJ.
In a solution, when the concentrations of a weak acid and its conjugate base are equal: 1. the -log of the concentration of H+ and the -log of the Ka are equal.
<h3>What are Strong acid strong bases ?</h3>
Any acid that entirely ionises in solutions is considered a strong acid. When positioned, it emits the most hydrogen ions or protons.
- It is a substance with the capacity to take a proton out of an extremely weak acid. In water, they can also entirely separate into its ions. Examples include sodium hydroxide and potassium hydroxide (KOH) (NaOH)
<h3>What are weak acid and weak bases ?</h3>
Acids that don't entirely dissociate in solution are referred to as weak acids. In other words, any acid that is not a strong acid qualifies as a weak acid. The amount of dissociation determines how strong an acid is; the more dissociation, the stronger the acid.
- Weak bases are basic compounds that, when dissolved in solutions, do not entirely separate into their constituent ions.
