Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
Answer:
Explanation:
When Tollen's test is done by aldehyde , silver ion is converted into silver which forms a layer which looks like a mirror.
Ag⁺ + e = Ag
It is a reduction process where silver(1) ion is reduced to metallic silver.
Aldehyde is oxidized to carboxylate ion.
CH₃CHO + 2 OH⁻ = CH₃COO⁻ + H₂O + H⁺ + 2e
Visual indicator is silver metal which forms silver mirror at the bottom of test tube .

I think its B. sorry if you get it wrong I'm not good at matg
Answer:
Here's where orbital hybridization came into play. According to this theory, when the carbon atom is in an excited state, one of the two electrons located in the 2s orbital will get promoted to the empty 2pz orbital. As a result, carbon now has 4 unpaired valence electrons with which it can form four bonds.
