Answer:
3HC2H3O2(aq) + Al(OH)3(aq) --> AI(C2H3O2)3(aq) + 3H2O(l)
Explanation:
HC2H3O2 is the chemical formula for Ethanoic acid which can be written as CH3COOH.
Hence, the balanced equation is stated as 3CH3COOH(aq) + Al(OH)3(aq) --> AI(CH3COO)3(aq) + 3H2O(l)
Acid + base → Salt + Water.
The equation is a neutralization reaction in which the acid, aqeous CH3COOH reacts completely with an appropriate amount of base, aqueous Al(OH)3 to produce salt, aqueous AI(CH3COO)3(aq)
and water, liquid H2O only.
During this reaction, the hydrogen ion, H+, from the Ethanoic acid is neutralized by the hydroxide ion, OH-, from the Aluminum hydroxide to form the water molecule, H2O and aluminium ethanoate.
Thus, it is called a neutralization reaction.
A thermochemical reaction is a chemical reaction with an additional information of the heat of reaction. For example, this is the thermochemical reaction for the combustion of hydrogen gas:
H₂ (g) + 1/2 O₂ (g) → H₂O (l) ΔH = -285.8 kJ
The coefficient 1/2 represents the number of moles of O₂ needed to combust 1 mole of H₂ gas in order to yield one mole of water.
Answer:
water was added to powdered rock
Explanation:
δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
The lead (Pb) in the lead storage battery act as an anode
<h3>What is Voltaic Cell?</h3>
A voltaic cell or galvanic cell is an electrochemical cell that uses chemical reactions to produce electrical energy.
<h3>Parts of voltaic cell</h3>
Anode where oxidation occurs Cathode where reduction occurs.
Therefore, Pb acts as anode and PbO2 act as a cathode.
Given,
E° cell = 2.04v
Faraday constant= 96485 C/mol
Moles of electron transferred n= 2
∆G = -nFE°
= -2 × 96485 × 2.04
= 393.658kJ
Thus we concluded that the δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
