Answer:
D. concentration, as the concentrations of reactants and products remain unchanged after equilibrium is reached.
Explanation:
I put it for the test and i got right hehe
Answer:
Balanced chemical equation:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
Explanation:
Chemical equation:
SeCl₆ + O₂ → SeO₂ + Cl₂
Balanced chemical equation:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
The above equation is balanced. There are one Se, six chlorine and two oxygen atoms are present on both side of equation The given balanced equation followed the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
