Answer:
The concentration of Hydrogen Cation is:
Pure water is<u> NEUTRAL</u>
Explanation:
pH = It is negative logarithm of activity of Hydrogen ions.
![pH = - log(a_{[H^{+}]})](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%28a_%7B%5BH%5E%7B%2B%7D%5D%7D%29)
Activity = concentration for dilute solutions
There are three types of solution based on pH:
1. Acidic solution : Those solution which have pH between 0 to 7 or less than 7 are acidic in nature . They turns blue litmus red.They contain more H+ ions than OH- ions
2. Basic : Those solution which have pH value greater that 7 of between 7 to 14 are basic in nature . They turn red litmus blue.They contain more OH- ions then H+ ions
3 . Neutral : Those solution which have pH = 7 are neutral . They are neither acidic nor basic in nature .They have equa;l concentration of H+ and OH- ions in the solution.
The given water has pH = 7 .This means it is neutral and has low H+ ion concentration in solution. The H+ ion are :
M in water.
OH- =
M in water
So overall neutral
Answer:
Explanation:
48000 minutes [ 1 hour / 60 min ] 1 day / 24 hours ] [365 days / year]
48000 * [ 1/(60 * 24 * 365)]
48000 * [1 / 525600]
There are 0.0930954years in 48000 minutes
Answer:
The answer is "From Chemical to Mechanical.".
Explanation:
In this question, chemical energy is an organic compound that includes contains energy from certain chains for the exergonic responses that happen when fuels emitters inside the form of heat throughout a chemical process, in which the skin converts the chemical energy in food into mechanical energy and heat.
Answer:
V₂ = 12.5 mL
Explanation:
Given data:
Initial volume = 100.0 mL
Initial pressure = 50.0 KPa
Final volume = ?
Final pressure = 400.0 KPa
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
50.0 KPa × 100.0 mL = 400 KPa × V₂
V₂ = 5000 KPa.mL/ 400 KPa
V₂ = 12.5 mL
