With the symbol of a chemical element - of course, if you think to a chemical formula.
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.
False
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
Well, it doesnt matter what equation an element is in it will always have the came valence, Carbon is 4+ as it is in Group IV.
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.
Yes.
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.
Moles of reactants and products thats wut i put on my test
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
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
Atomic weight. It's always the bigger number.
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
AgCl It always has a valency of +1, though it is a transition metal
no.
It is only a convention.
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
