If the glowing splint bursts into flames during the decomposition of H2O2, it will indicate at gas which will be produced. And that gas that is produced because of the glowing splint bursts is the type of gas called oxygen.
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
<u>Answer:</u> The molarity of stock solution of luminol is 1.055 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of luminol = 14.0 g
Molar mass of luminol = 177 g/mol
Volume of solution = 75.0 mL
Putting values in above equation, we get:
Hence, the molarity of stock solution of luminol is 1.055 M
When two atoms are close to each other they tend to repel and when they are far away but hasn’t still broken the limit they tend to attract but sorry I don’t want to give u a wrong answer I don’t know
