The reactions taking place inside a lead accumulator are said to be redox reactions describe the chemical reaction and justify the statement?
The chemical reaction occurring in a lead-acid battery, also known as a lead accumulator, involves a redox reaction between lead dioxide (PbO2), lead (Pb), and sulfuric acid (H2SO4). The reaction can be represented as: PbO2 + Pb + 2H2SO4 → 2PbSO4 + 2H2O. This reaction involves the transfer of electrons between the lead and lead dioxide, leading to a change in oxidation states, which is characteristic of redox reactions. The lead-acid battery relies on these redox reactions to convert chemical energy into electrical energy.
When is a reaction said to be unfavorable?
A reaction is said to be unfavorable when it requires more energy to occur than it releases.
What can be said about a reaction with H 62.4 kJ mol and S 0.145 kJ mol K?
it is spontaneous at 500 k
Ask us anythingUse the reaction I2(s) I2(g) H 62.4 kJmol S 0.145 kJ(molK) for question 10. What can be said about the reaction at 500 K?
At 500 K, the reaction will favour the formation of gaseous I2 since the positive change in enthalpy indicates the reaction is endothermic. The positive change in entropy suggests an increase in disorder, further favoring the formation of gaseous I2 at higher temperatures.
What can be said about a reaction with H 620 kJmol and S -0.46 kJ molK?
it can never be spontanious
The substance that accepts electrons from another substance is the?
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.

When a metallic element is converted to a positive ion during a chemical reaction with oxygen the metallic element is said to be?
The metal become a cation.
What can be said about the reaction?
What reaction to what? You didn't specify.
What can be said about a reaction with delta H 62.4 kJmol and delta S 0.145 kJ(mol K)?
A reaction with a positive ΔH of 62.4 kJ/mol indicates that it is endothermic, absorbing heat from the surroundings. The positive ΔS of 0.145 kJ/(mol K) suggests that the reaction leads to an increase in entropy, favoring disorder. To determine the spontaneity at a given temperature, the Gibbs free energy change (ΔG = ΔH - TΔS) can be evaluated; if ΔG is negative, the reaction is spontaneous. At higher temperatures, the positive entropy change may make the reaction more favorable.
Describe What happens during a reduction-oxidation reaction?
Electrons are transferred from one molecule or ion to another. The substance that loses electrons is said to be oxidized, the one that gains the electrons is said to be reduced. -A Muslim

When a chemical reaction and it's reverse occur at the same time and rate the reaction is said to be?
When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about

it can never be spontanious
When the actual free energy change of a reaction change in G has a numerical value of less than zero negative number what will happen?
When the delta G is negative the reaction is said to be spontaneous or in other words favorable. It also means the reaction is irreversible once full product concentration is reached. If delta G is positive, the reaction is unfavorable thus can easily be reversed. If it is zero it is at equilibrium.
