Answer: The concentration of hydrogen ions is and the concentration of hydroxide ions is . Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Putting in the values:
Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
Answer:
Products are stearate anion and water.
Explanation:
Stearic acid is a 18-carbon chain molecule containing -COOH group. IUPAC name of stearic acid is octadecanoic acid.
Molecular formula of stearic acid is .
When is added into stearic acid, removes a proton () from acidic -COOH group and forms stearate anion and water as products.
The balanced acid-base reaction is given as:
Structure of products are given below.
Answer:
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Explanation:
According to the Arrhenius equation,
where,
= rate of reaction at
= rate of reaction at
= activation energy of the reaction
R = gas constant = 8.314 J/K mol
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
The concentration of a and b will decrease while c will increase provided all other physical quantities are kept constant in the reaction
