Answer:
oxidation reaction.
Explanation:
Every reduction reaction must be accompanied by an oxidation reaction.
Oxidation leads electrons loss whereas reduction implies gain of electrons. So missing electrons should always be the equivalent of obtained electrons. Without something acquiring electrons there can't be any loss. Electrons can't simply disappear!
It implies, but, that oxidation and reduction must occur simultaneously at different locations and the electrons can commute across cables or in a liquid medium by ions.

Answer:
HNO3(aq) + OH-(aq) → NO3-(aq) + H2O(l)
Explanation:
According to Bronsted-Lowry theory, an acid is a substance that donates a proton (H+) and produces a conjugate base while a base is a molecule or ion which accepts the proton.
An example of Bronsted-Lowry acid and base is Nitric acid, HNO3 and hydroxide ion, OH- respectively as shown in the given reaction.
Thus, the nitric acid acts as an acid by donating a proton to the hydroxide ion which accepts it, thus producing nitrate ion, NO3- as a conjugate base, while OH- produces H2O as a conjugate acid.
Answer:
Explanation:
Let's consider the following chemical equilibrium:
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
Given the pressure equilibrium constant Kp = pCO₂
We can calculate the concentration equilibrium constant (Kc) using the following expression.
where,
R is the ideal gas constant
T is the absolute temperature
Δn(g) = moles of gaseous products - moles of gaseous reactants = 1 - 0 = 1
The expression for this reaction is:
The alchemists were the first chemists, but they were also mixing chemicals, they believed that magic would help with their experiments.but it didn't. but their experiments of the science of chemistry did.<em><u></u></em>
