Is a chemical equation balanced by changing or adding?
The subscripts determine what the chemicals are, you have to change the amount of the reactants/products rather than change what the reactants/products actually are eg O2 is oxygen gas, if you wanted 4 of them to balance it it would have to be 2 O2 otherwise it wouldn't be oxygen gas any more.
What characteristic of life would maintaing this balance be?
It depends what on what balance your talking about
Why is the equation H2 O2H2O incorrect?
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.
How would you measure 5 grams of salt?
I would place the watch glass on a balance, and then zero out the balance with the watch glass placed in the tray. After the balance is balanced with the watch glass, I would move the weights to represent an added five grams. I would then slowly add calcium chloride to the watch glass until the balance rebalances or zeroes out.
Why carnivores in grassland?
There would be nothing to preserve and balance the amount of large grazing herbivore on the grasslands if there were not carnivores. Remember that nature is all about balance!

What would you change to balance a chemical equation?
you would change the coefficients
What coefficients balance the equation Fe O2 Fe2O3?
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
Why are coefficient used to balance equations?
Coefficients are used to balance equations because if you change the subscript, than you would change the substance.
What is the set of coefficients that would balance the equation cr2o3 plus cr2so43 plus li2o?
1,3,1,3
What correlation coefficients represents a situation in which there is no relationship between variables?
We would need to have the list of correlation coefficients to respond to this question.
What coefficients can be used to balance this epuation H2 NaCl2 NaH Cl?
First off, it is going to be NaCl, not NaCl2 and Cl2, not Cl. Secondly, the balanced equation would be H2 + 2NaCl -> 2NaH + Cl2
How do you find the moles recquired?
In order to find the number of MOLES, you must find the relation to said MOLES. Always remember to balance the equation to determine the coefficients. That would be in order to find the relation between them.
What do you call the numbers used to balance equations?
The numbers placed immediately before formulas of compounds and/or elements involved in the reaction are called "coefficients" and those placed immediately after element symbols, depressed below the typographical line of the element symbol are called "subscripts". The subscripts show the number of atoms of a particular element in a formula unit of a molecule or other compound.
How would you differentiate rational algebraic expressions from those which are not?
The coefficients in a rational expression would be rational numbers.
I do not understand how to figure out the products of reactants such as K3PO4 and HCl?
What is the charge of the PO4 ion? It is -3. Potassium (K) is +1. So K3PO4 is balanced, as you would expect. The hydrogen ion is +1, and chlorine (Cl) is -1, so it is balanced. You need 3 hydrogens to offset phosphate (PO4). K3PO4 + 3HCl = K3Cl3 + H3PO4 Everything has to equal. You have 3 potassiums on one side, you must end up with three on the other. Do you get phosphoric acid when you mix these reactants? Or do you instead get phosphor and water?
Why you use coefficients in equations?
in order to balance equations, coefficients are placed in front of the various compounds/elements. This is done so that the same number of atoms are produced on each side of the equation. For example: *2*H20 = *2*H2 + 02 The numbers with asterisks on either side of them are coefficients. Without them, there would be only one hydrogen atom on the products side and two on the reactants side. In order to preserve the law of conservation of mass, you must add a coefficient of two. So, you multiply the coefficient by the however many atoms there are. Then, the equation is balanced and your teacher is happy.
A solution contains 2.0 x10-5 m K3PO4 what is the minimum concentration of AgNO3 that would cause precipitation of solid Ag3PO4 ksp1.8 x10-18?
it would be 1 because you'd have to subtract it to get the minimal
