The balanced equation is: SiO2 + 3C → Si + 2CO.
Since there are no "following" equations, the answer is NONE OF THEM.Since there are no "following" equations, the answer is NONE OF THEM.Since there are no "following" equations, the answer is NONE OF THEM.Since there are no "following" equations, the answer is NONE OF THEM.
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Mole Ratios
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
Conservation of mass.
Some examples of unbalanced equations include: CH4 + O2 -> CO2 + H2O (the number of oxygen atoms is not balanced) Mg + HCl -> MgCl2 + H2 (the number of chlorine atoms is not balanced)
Properly balanced equations are necessary in chemistry to accurately represent the conservation of mass and atoms in a chemical reaction. Balanced equations ensure that all reactants are accounted for and that the number of atoms remain the same on both sides of the reaction.
Which of the following is a disadvantage to using equations?
the law of conservation of mass.
It would help very much if the "following equations" actually DID follow!
They are necessary for accurate chemical calculations.
