E
Answer:
The chemical bonds of the solid are broken faster.
Explanation:
As the temperature of a solution is increased, the average kinetic energy of the molecules that make up the solution also increases. The increased vibration (kinetic energy) of the solute molecules causes them to be less able to hold together, and thus they dissolve more readily.
Answer:
C
Explanation:
Natural gas is a non renewable source of energy since it is a type of fossil fuel so it is a non renewable resource.
Answer:
5 atoms of hydrogen will be found in the products
Explanation:
5 atoms of hydrogen will be found in the products becuase the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
Answer:
See Explanation
Explanation:
The Law of Conservation of Matter as applied to chemical reactions says that matter is neither created nor distroyed, only changed in form. This implies that the mass of substances going into a reaction process must equal the mass of products generated during the reaction process.
Empirically,
∑ mass reactants = ∑ mass products
One can test this idea after balancing a chemical equation by determining the sum of formula weights of reactants and products; then compare. If reaction was properly balanced, the total mass reactants = total mass of products.
Example:
Combustion of Methane => CH₄(g) + 2O₂(g) => CO₂(g) + 2H₂O(l)
Equation Weights => 16amu + 64amu <=> 44amu + 36amu
Mass Reactants = Mass Products => 80amu <=> 80amu.
