Explain what is meant by a chemical equation being balanced?
Placing coefficients in front of compounds or elements or poly-atomic ions to balance the number of atoms of different elements between the reactants side and the products side. Ex. CH4 + 2 O2 CO2 + 2 H2O
Explain what a coefficient in a balanced chemical equation represents?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
Explain how a balanced equation demonstrates the law of mass?
A balanced equation specifies the same total number(s) of each type of atom present in both the reactants (left side of the equation) and the products (right side of the equation.) The average mass of each type of atom is constant in most circumstances*, so that the same numbers of the same types of atoms will constitute the same mass on each side of the equation, demonstrating the law of conservation of mass. __________________________________ *When only a very small number of atoms are considered, the mass may vary due to the existence of isotopes. However, even then, the isotopic composition of the actual atoms involved in the reaction is not changed by chemical reaction, so that the mass balance still is preserved.
Why do scientist use chemical equations to explain chemical reactions?
Because it's fun
What is the purpose of a chemical equation?
I don't remember all of the mathematical names, but I do remember that you need to balance equations so that both sides will be equal. These are very simple examples but they will show you that balanced equations are equivalentto being equal.Such as: (2+2)=4=(3+1) Both sides equal '4'.Differing equations on opposite sides of the equal sign demonstrate that are differing ways to express a certain figure.Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal '5'.(8) - (3) =5= (4) + (1)Hope this helps.
When chemical reactions occur matters is conserved explain what that means?
No
What law of chemical change is obeyed when a chemical equation is balanced and explain?
conservation of mass law, no matter is ever created or destroyed (except for nuclear fusion)

What is a purpose of a chemical equation?
A chemical equation lets humans explain a chemical reaction. When the same reaction occurs repeatedly, the equation serves to remind us of what happened in the reaction.
As the equation is written which element is not in balance Explain?
An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with

How does nuclear reaction occur in the sun explain with a chemical equation?
can't be explained in chemical equation as it is nuclear. reaction is fusion of ionized hydrogen nuclei into ionized helium nuclei. every other hydrogen nucleus transforms from a proton to a neutron in the process.
