Answer:
pH = 2,4
Explanation:
pH is defined as a measure of acidity or alkalinity of a solution based on H⁺ concentration
The HCl dissociates in water thus:
HCl → H⁺ + Cl⁻
That means that moles of HCl are the same than H⁺.
0,35gHCl
= 9,6x10⁻³ moles HCl ≡ moles H⁺
H⁺ molarity is: 
= 3,84x10⁻³M
As pH = -log [H⁺]
<em>pH = 2,4</em>

Answer:
The following three isomeric structure are given below.
Explanation:
Structure of the following three isomeric esters with chemical formula C₇H₁₂O₂
Ester #1: methyl 1-methylcyclobutanecarboxylate
Ester #2: (E)-methyl 3-methyl-3-pentenoate
Ester #3: isopropyl 2-methylpropenoate
Answer:
The Equilibrium constant K is far greater than 1; K>>1
Explanation:
The equilibrium constant, K, for any given reaction at equilibrium, is defined as the ratio of the concentration of the products raised to their stoichiometric coefficients divided by the concentration of reactants raised to their stoichiometric coefficients.
It tells us more about how how bigger or smaller the concentration of products is to that of the reactants when a reaction attains equilibrium. From the given data, as the color of the reactant mixture (Br2 is reddish-brown, and H2 is colourless) fades, more of the colorless product (HBr is colorless) is being formed as the reaction approaches equilibrium. This indicates yhat the concentration of products becomes relatively higher than that of the reactants as the reaction progresses towards equilibrium, the equilibrium constant K, must be greater than 1 therefore.
