Answer : The concentration is, 0.0316 M
Explanation :
pH : It is defined as the negative logarithm of hydrogen ion concentration.
First we have to calculate the pOH.
Now we have to calculate the concentration.
Therefore, the concentration is, 0.0316 M
For a neutralisation reaction...
Acid + base 》 salt + water....
The above reaction looks much alike so is a neutralisation...
It is certainly not compustion as no oxygen to react and CO2 produced
Answer:
The correct answer is 29 grams.
Explanation:
Based on the given question, the reaction will be,
CH3CH=CHCH3 + H2 ⇒ CH3CH2CH2CH3
The molecular weight of butene is 56 grams per mole, and the molecular weight of butane is 58 grams per mole.
Thus, it can be said that 56 grams of butene reacts with hydrogen gas and produces 58 grams of butane.
Therefore, 28 grams of butene when reacts with hydrogen gas to give,
= 58/56 * 28 = 29 grams of butane.
Hence, the mass of butane produced will be 29 grams.
