Which statement about the balanced equations for nuclear and chemical changes is correct?
A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. Both are balanced according to the mass number of each element before and after the change. Both are balanced according to the total mass before and after the change. Both are balanced according to the total mass before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Both nuclear and chemical equations are balanced according to the mass number of each element before and after the change.
The correct statement is:
A chemical equation is balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to the total mass before and after the change.
The correct statement is: A nuclear equation is balanced according to the total mass before and after the change, while a chemical equation is balanced according to the mass number of each element before and after the change.
In order to balance a chemical equation, you need to ensure that there are the same number of each type of atom on both sides of the equation. This is done by adjusting the coefficients in front of the chemical formulas to achieve an equal number of atoms.
On the other hand, nuclear equations describe the changes that occur in the nucleus of an atom, such as radioactive decay or nuclear reactions. In a nuclear equation, you need to balance both the mass numbers and atomic numbers on both sides of the equation, as well as the total charge.
So, in summary, a chemical equation is balanced based on the mass number of each element, while a nuclear equation is balanced based on the total mass before and after the change.
