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.

What do chemical equations describe?
Chemical equations describe the chemical reactions that occur between reactants to form products. They show the substances involved in the reaction and the ratio in which they combine.
Why energy is necessary to chemical reactions and describe some common sources of energy.?
Energy is necessary for chemical reactions because it allows molecules to overcome activation energy barriers and initiate reactions. Common sources of energy for chemical reactions include heat, light, electricity, and catalysts. These sources provide the necessary energy to break existing bonds and form new ones during a chemical reaction.
Why scientists use chemical equations to describe chemical reactions?

Describe the role of energy in chemical reactions?
Energy is required to break bonds between atoms in reactant molecules, allowing them to rearrange into new products. This energy is called activation energy. Some reactions release energy, called exothermic reactions, while others absorb energy, called endothermic reactions. Overall, energy is essential for driving chemical reactions and determining whether they proceed or not.
Which statement does NOT describe a chemical equation 1. The products are placed to the of the arrow. 2. Atoms must be balanced on both sides of the arrow. 3. The arrow represents the direction in wh.?
Statement 3 does NOT describe a chemical equation. It should read: "The arrow represents the direction in which the reaction is proceeding."
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
What do chemical equations describe?
Chemical equations describe the chemical reactions that occur between reactants to form products. They show the substances involved in the reaction and the ratio in which they combine.
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.
Do chemical equations describe chemical reactions?
A chemical equation is a short way to describe a chemical reaction, so yes.
