No, but both describe the same chemical reaction.
No, they are not the same.
If the number of atoms of each element is the same on both sides of the equation, then it is balanced.
the number and type of atoms of reactant and product are the same
Balanced and unbalanced chemical equations have the same elements on both sides, they have just been recombinded to form new products from the reactants.
A nuclear equation is balanced when the sum of atomic numbers and mass numbers on each side of the equation is the same.
Well it fully depends on what type of copper you have. if you have Cu1+ then when you do an ionic equation and switch the ion charges, then the compound you would get would be Cu2O. If you had Cu2+ then the compound would end up being CuO. You cant just put two things together and assume its right. You have to do an ionic equation and then balance your reaction.
Atoms
They simply have the same numbers of atoms each element on one side of the equation as the other side.
For the same reason as a mathematical equation. The word equation is derived from EQUAL - so to be equal or balanced there has to be the same number of atoms on each side.
A balanced equation is that equation which obeys the law of conservation of mass.(Added: also the law of conservation of (the kind of) elements should be obeyed).In such an equation the number of atoms for each elementin the reaction and the net or overall charge is same for the reactants and products.
chemical equations must be balanced according to the law of conservation of mass: mass cannot be created or destroyed. In other words: it's impossible to have an unbalanced equation that is correct, so do what your teacher tells you to.
As no chemical equations create or destroy new molecules, both sides need to be balanced to show the same amount of each element is on either side of the equation.
An equation is balanced if each atom on both sides are the same amount
Simultaneous equations have the same solutions.
Which of the billions of possible equations that contain aluminum are you asking about?
The equations are equivalent.
if you balanced the equation correctly then the sum of the reactants will equal the sum of the the products because if there is the same amount of atoms on the reactants and the products obviously none is lost.
Consistent equations are two or more equations that have the same solution.
