the universe formed through the big bang explosion, all of the elements on Earth have been cooked for billions of years in stars and then released in the universe through super- nova explosions.
Haber process is the large scale manufacture of a ammonia by reacting nitrogen and hydrogen at a ratio of 1:3
Change in hydrogen concentration is 0.45 - 0.16 = 0.29 moles/l
Therefore, the average rate of reaction of hydrogen = 0.29 / 30 = 0.0096
= 0.0096 moles/liter/sec
Answer:
2nd option
Explanation:
it means that there are 8 carbons
Answer:
pH = -log(concentration of hydro.gen ion)
1. When con. of H ion is 1*10-4 mol/L
pH = -log(1*10-4) = -(-4) = 4
2. A solution with a pH of 1*10-12mol/L
pH = -log (1*10-12) = -(-12) = 12
The pH is 12 and the solution is basic or alkaline
3.A solution with a pH of 6 has the concentration of
pH = -log (H+)
(H+) = arc log -pH
(H+) = 1*10-6
Explanation:
As we know that neutralization reaction is a reaction in which base react with acid to form salt and water.
When Potassium Hydroxide reacts with Sulphuric Acid, it forms Potassium Sulphate and Water.
As a result of neutralization reaction, Potassium Sulphate and Water is formed.
2KOH + H2SO4 ----> K2SO4 + 2H2O
Here, K2SO4 is found in aqueous medium in neutralization reaction. It is a neutral salt.
