\(\text {Zinc}+ \text {Sulphuric acid} \rightarrow \text {Zinc sulphate} + \text {Hydrogen gas}\) This is known as a word equation. By writing the symbols and formulae of the various substances in place of their names, we can convert this word equation into a chemical equation. ...
In a word equation – The reactants and products are separated by an arrow between them. Reactants are written on the left-hand side of the arrow (LHS) with a (+) sign between them. Products are written on the right-hand side of the arrow (RHS) with a (+) sign between them. ...
In some chemical reactions, a substance called a catalyst is used. A catalyst speeds up a reaction without being used up Because a catalyst is not used up, it is neither a reactant or a product and is written above the arrow in the equation. 2H2O2(aq) ---> 2...
Write the balanced equation for this reaction. Complete the following word equation and write a formula equation for this reaction. potassium + arrow hydrogen + potassium hydroxide Write a balanced equation for the following reaction: The reaction of potassium with...
(8) and (9) are included in many other texts (White, 2020; Brantley, 2008). Importantly, collision theory and the Arrhenius equation fail to describe reactions between more complex molecules that cannot be approximated as spheres and require specific alignment to bond with reactants. We turn ...
