Chemical formulas of reactants and products; number of molecules involved in the reaction.
A chemical equation is the representation of a chemical reaction.
A plus sign in an equation is used to indicate addition. It shows that elements or terms are being combined to find the sum.
A chemical equation can be interpreted in terms of molecular, ionic, or net ionic equations. In a molecular equation, all reactants and products are written as complete compounds. In an ionic equation, all soluble compounds are dissociated into their respective ions. In a net ionic equation, spectator ions are omitted to show only the species that participate in the chemical reaction.
No, NaCl H2O is not a chemical equation. An equation must have an equal sign. And even if you put an equal sign into those terms, it is not true that NaCl = H2O, so that would be a false equation, not a complete and balanced equation. You are not even close to having that.
Examples: NaCl, H2, =, +, ----------------->, ↔, (s), etc.
H2O represents the chemical formula for water, which is a chemical compound. In terms of type of equation, it is a molecular formula that shows the number and type of atoms present in a molecule of water.
Chemists keep track of substances used and created in a chemical reaction by writing a balanced chemical equation. This equation accounts for the reactants (substances used) and products (substances created) in terms of their chemical formulas and stoichiometry. Balancing the equation ensures that the law of conservation of mass is obeyed.
That depends on the specific equation. The general idea is to "isolate" the variable, for example "x", manipulating the equation in such a way that all terms that contain "x" are on the left, and all terms that don't contain it, are on the right.
If a form of energy appears on the right side of a chemical equation, it means that energy is being released during the reaction, often in the form of heat. This is indicated by terms like "heat," "ΔH," or "energy" on the product side of the equation.
Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
There are two terms: 3x, -2b. Yeah, two terms. But where is the equation?
