What has to happen for a chemical equation to be balanced?
There has to be the same numbers and types of elements on both sides of the equation. This is accomplished by adding coefficients in front of the chemical formulas as needed. Never change a formula when balancing an equation.
What is the balance of chemical equation involve in evaporation?
Evaporation is not a chemical change and so there is no chemical equation.
A chemical reaction is balanced by changing?
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts.When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the number of molecules of one or more reactants or products. When the number of atoms of each element is equal on both sides of the equation, and cannot be reduced equally, the balancing process is complete.
What is the only part of a chemical equation you can change?
You can only change the coefficients.
How is the best describes a balance reaction?
The correct answer is: A reaction that has the same number and type of atoms on each side of the equation.
Copper chloride aluminum foil physical change?
whats the balanced chemical equation
Is every chemical change able to be written down as a chemical equation or only some of them?
yes and they are able to be balanced.

Is photosynthesis a chemcal change?
Yes, the balanced chemical equation is as follows: 6CO2 + 6H2O yeilds (or changes to) C6H12O2 + 6O2.
What is the chemical equation for climate change?
Climate change is not a chemical reaction, and it is not described by a chemical equation.
When you have a chemical change is the mass of what you start with less equal or greater than what you end with?
If the equation is balanced, the mass will be the same on each side of the equation. Matter cannot be created or destroyed.
What is the balanced equation of mercuryII oxide HgO undergoes a chemical change to form mercury and oxygen?
the balanced equation of mercuryII oxide HgO undergoes a chemical change to form mercury and oxygen is given as .2HgO(s) --> 2Hg(l) + O2(g)The reaction is a redox reaction. Mercury (II) is reduced to zero charge. Oxygen is oxidized to zero charge.Molecule: HgO(s)

What do scientists do to indicate a chemical change occurrence?
They write a chemical equation.
