yes, albert is better grffffrr#fffffrttt.
Explanation:
<u>Answer: </u>The mass of sample that remained is 0.127 mg
<u>Explanation:</u>
The integrated rate law equation for first-order kinetics:
......(1)
Given values:
a = initial concentration of reactant = 0.500 mg
a - x = concentration of reactant left after time 't' = ?mg
t = time period = 28 s
k = rate constant = 
Putting values in equation 1:
Hence, the mass of sample that remained is 0.127 mg
Aldehydes may oxidize to form carboxylic acid <span>exception to oxidizing formaldehyde with strong oxidizing agent.
HCHO + 3[O] = CO</span>₂ + H₂O
find the answer in the attached image. please mark as brainliest if it is helpful.
The correct answer is B.
Strong acids completely dissociates to give hydrogen ions . Weak bases can only partially dissociate to give hydroxide ions .
Therefore when equal amounts of acid and base are mixed, while Acid is completely dissociated and gives out hydrogen ions but base only gives out a fraction of hydroxide ions.
Therefore number of hydrogen ions in the solution will be higher than hydroxide ions, resulting in an acidic pH. Therefore pH <7
