What does the double ended arrow indicate in the following chemical equation?
The double-ended arrow in the chemical equation indicates a reversible reaction. A reversible reaction is a reaction in which the conversion of reactants into products and the conversion of products into reactants can happen simultaneously.
What does the arrow in a chemical reaction represent?
Reaction arrows are used to describe the state or progress of a reaction. The chemical reaction arrow is one straight arrow pointing from reactant(s) to product(s) and by-products, sometimes along with side products. The single arrow emphasizes one direction of chemical change (from A to B).
What does chemical reaction do?
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What is the significance of double arrow in an equation?
The double arrow denotes a reversible reaction. The reactants become products and the products can become reactants again using the same process.
What happens when dynamic equilibrium is reached?
Dynamic equilibrium occurs when, for a reversible reaction, the rate of the forward reaction equals the rate of the reverse reaction. Since the two rates are equal, it looks like nothing is happening, but in reality the reaction is continuously occurring at its stable rate.
What does S mean in a chemical equation?
The physical state of chemicals is also very commonly stated in parentheses after the chemical symbol, especially for ionic reactions. When stating physical state, (s) denotes a solid, (l) denotes a liquid, (g) denotes a gas and (aq) denotes an aqueous solution.
Why is the following chemical equation not balanced h2 o2 –> h2o?
The obtained result indicates that the oxygen atom is not equal on both sides. Thus the reaction is not balanced. The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal.
What type of reaction is Zn H2SO4 ZnSO4 H2?
SINGLE REPLACEMENT (also called DISPLACEMENT): General form: A + BC → AC + B (“A displaces B”) Examples: Zn + H2SO4 → ZnSO4 + H2 Mg + 2 AgNO3 → Mg(NO3)2 + 2 Ag In these, a “more reactive” element displaces a “less reactive” one from a compound. These reactions always involve oxidation and reduction.
