Answer:
pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots the concentration of solutions in a range from 0–14.
Explanation:
The pH is a measure of the hydrogen ion(H^+) concentration in an acid or base. It can be obtained mathematically by the formula:
pH = —Log [H^+]
The pH scale ranges from 0 to 14
According to Le Chatelier’s principle, if the dynamic equilibrium of a system is disturbed by any change in the conditions of the system then the equilibrium will adjust itself in such a way that new equilibrium moves to counteract the change.
Hence, when the concentration of reactants is doubled in a chemical reaction that was in equilibrium then the equilibrium shifts to the right to favor the formation of products.
<h2>5060 have three significant figures : Explanation given below </h2>
Explanation:
Significant figures
The significant figures (also known as the significant digits and decimal places) of a number are digits that possess certain meaning .
It includes all digits except: zeros
Rules to find significant figures
1.All non-zero digits are considered significant. For example, 23 has two significant figures.
2.Zeros in between two non-zero digits are significant: like in 202.1201 has seven significant figures.
3.Zeros to the left of the significant figures are not significant. For example, .000021 has two significant figures, zeros have no value .
4.Zeros to the right of the significant figures are significant.
That is the reason in number 5060 , it has 3 significant figures .
I will chill a container so that its outer surface is very cold, but dry. Then I will
wave the container through the air, and point out the liquid water from the air
that collects on the cold outer surface of the container.
