In vocal cord paralysis, the nerve impulses to your voice box (larynx) are disrupted, resulting in paralysis of the muscle. Doctors often don't know the cause of vocal cord paralysis. Known causes may include: Injury to the vocal cord during surgery.
A balanced equation shows how many moles of each reactant is needed to form a certain number of moles of product. a balance equation must show a subscript change from elements. A balanced chemical equation has the same number of atoms of each element on both sides. The mass of the reactants is equal to the mass of products.
The balanced equation is: 2 Fe2O3 + 3 C â 4 Fe + 3 CO2. Both the left and right sides of the equation have 4 Fe, 6 O, and 3 C atoms. When you balance equations, it's a good idea to check your work by multiplying the subscript of each atom by the coefficient. When no subscript is cited, consider it to be 1.
