Which equation obeys the law of conservation of mass?
The equation 2H2 + O2 -> 2H2O obeys the law of conservation of mass. This balanced chemical equation shows that the total mass of the reactants (hydrogen and oxygen) equals the total mass of the products (water).
How does a balanced chemical equation shows that mass is conserved?
A balanced chemical equation shows that mass is conserved because the total mass of the reactants before a chemical reaction must equal the total mass of the products after the reaction. This is achieved by ensuring that the number of atoms of each element is the same on both sides of the equation. Therefore, what is consumed on the reactant side is equal to what is produced on the product side, preserving total mass.
Explain how the balancing of chemical equation shows that mass is conserved?
Balancing a chemical equation ensures that the number of atoms of each element on the reactant side is equal to the number on the product side. This conservation of atoms implies the conservation of mass. When the equation is balanced, the total mass of the reactants is equal to the total mass of the products, demonstrating the law of conservation of mass.
What equation shows conservation of both mass and charge?
The equation that shows conservation of both mass and charge is the continuity equation, ∂ρ/∂t + ∇⋅J = 0, where ρ is the charge density and J is the current density in an electromagnetic field. This equation states that the rate of change of charge density plus the divergence of the current density must equal zero, implying that charge is conserved locally. Additionally, in nuclear reactions, mass-energy equivalence (E=mc^2) relates the conservation of mass and energy.
Explain how a balanced equation supports the law of conservation of mass?
A balanced chemical equation shows that the total mass of reactants equals the total mass of products, which supports the law of conservation of mass. This law states that mass cannot be created or destroyed in a chemical reaction, only rearranged. By balancing the equation, we ensure that the number of atoms of each element is the same on both sides, preserving mass.
