What else can I help you with?
The Law of Conservation of Mass states that the equation for a chemical reaction will always be unbalanced?
That statement is incorrect. The Law of Conservation of Mass states that mass is conserved in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products, leading to a balanced chemical equation.
What are the parts of a balanced chemical equation?
A balanced chemical equation must observe the law of conservation. There must always be the same number of the atom within the reactants and within the products. For example, in the reaction between NaOH and HCl: NaOH + HCl --> NaCl + H2O On both sides of the equation, I have 2 hydrogen atoms, 1 chlorine atom and 1 sodium atom.
What symbol is always use in front of a formula?
With the symbol of a chemical element - of course, if you think to a chemical formula.
Why Is it incorrect to change the subscript of a balanced equation?
The subscript numbers give you the chemical composition of the compound. Hence it cannot be changed. E.G. water is H2O and cannot be written as anything else. likewise, carbon dioxide is always CO2. I hope this answers your question
When balancing a chemical equation is there more than one possible answer?
Technically no, but if you count factorising the number of specific molecules then there is, but it should always be given in the lowest common factor, for example: 6CO2 + 6H2O -> C6H12O6 + 6O2 (photosynthesis) could also be written as: 12CO2 + 12H2O -> C6H12O6 + 12O2 But you would always use the lowest factors for chemical equations, thus the '12's become '6's as they are common factors.
Which quantity must always be the same on both sides of a balanced chemical equation?
The numbers of atoms of each elemental type, as represented by their element symbols, will always be the same on both sides of a balanced chemical equation.
How can one tell if a chemical reaction is balanced?
If it is balanced then the mass (amount) of elements on each side of the arrow will be equal.count the number of molecules of each element on each side of the equation. they need to all be equal.An example:H2 + O2 -> H2O2There are two H's on the left hand side and two on the right hand side, so the H's are balanced.The same is for the O's.==> The equation is balancedAnd remember that the arrow is a yield sign in an equation.
Why is it always essential to balance a chemical equation?
Balancing a chemical equation is essential to ensure the law of conservation of mass is obeyed. This means that the number of atoms of each element remains the same on both sides of the equation. A balanced equation also helps in determining the correct stoichiometry of a reaction and predicting the amount of reactants needed or products formed.
Is it true a chemical equation must always be balanced because matter keeps its original properties?
Yes.
Why are chemical equations always balanced?
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
How does a chemical equation show that matter is always conserved in a chemical reaction?
According to the Law of Conservation Of Mass,Matter is neither created nor destroyed.It means a chemical equation show that matter is always conserved in a chemical reaction.It is shown as number of atoms both sides of the reaction before and after remains the same.
Coefficients in a balanced chemical equation always can express the ratio of?
Moles of reactants and products thats wut i put on my test
What parts of a chemical equation always follow after the arrow?
A chemical equation is defined as the short-hand representation of a true chemical reaction with the help of symbols and formula.A chemical equation is formed by reactants and products.Products of a chemical equation always follow after the arrow
The Law of Conservation of Mass states that the equation for a chemical reaction will always be unbalanced?
That statement is incorrect. The Law of Conservation of Mass states that mass is conserved in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products, leading to a balanced chemical equation.
What can the coefficients in a balanced chemical equation always express the ratio of?
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
What are the parts of a balanced chemical equation?

Numbers placed in front of chemical symbols and compound formulas in chemical equations are called what?
Atomic weight. It's always the bigger number.
