Answer:
LiHCO3 its PH >7
Explanation:
the real ph for it is 11.3 so it makes it more than 7
and if you know it is a conjugate base coming from the weak acid H2CO3 so LiHCO3 is a base
The answer to this question is false
The thermal energy of a substance is related to the movement of the particles in the substance. This energy is defined by the temperature of the substance and whether heat is transferred or lost. This can be explained as a higher temperature causes the particles in substances to move faster and collide.
Answer:
moles react.
Explanation:
In a chemical reaction equation, we know that chemical species react in moles. It is actually the moles of the individual chemical species that participate in a chemical reaction and not the masses of those species.
In solving stoichiometric problems, it is mandatory to use moles as a conversion factor in calculating the mass of product formed or the mass of reactant consumed. We often read off the number of moles that reacted from the balanced reaction equation and then convert the reacting mass of species given to the number of moles of that specie that actually participated in the reaction in order to obtain any required information from a reaction.
Answer:
[CH₃COOH] = 1.70 M
Explanation:
When we talk about concentration we can determine Molarity
Molarity determines the moles of solute that are contained in 1L of solution.
In this case our solute is the acetic acid.
M = mol/L
M = 0.99 mol /0.58L → 1.70 M
We can also make a rule of three
In 0.58 L of solution we have 0.99 moles of solute
In 1 L of solution we may have (1 . 0.99) / 0.58 = 1.70 moles
Acetic acid is a weak acid, partially dissociated in water.
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
