Word equations help in learning chemistry because they reinforce the thought process involved in writing a chemical reaction or equation.
The phrase "is reacted with" indicates the chemicals are reactants. The solution absorbs moisture from the air, so growth is hard enough. which means: Zn + Pb (NO 3) 2 → Zn(NO 3) 2 + Pb Why Use Word Equations? Add to the flask with calcium or lead nitrate solution small parts of iron salt solution and stir. This is mostly for the transition metals, which can have multiple oxidation states. Do not store in matchboxes or cotton wool and do not heat. Yahoo is part of Verizon Media. In any chemical reaction, you need to be able to identify the chemical species that react with each other and what they make. Information about your device and internet connection, including your IP address, Browsing and search activity while using Verizon Media websites and apps. Addition, subtraction, multiplication, division, logs, square roots, integrals, and other operations can be stated in word equations. This page was last edited on 13 January 2018, at 21:17. Add acid to the flask, then add small parts of iron compound with stirring until it will totally dissolve or, if you use carbonate, until carbon dioxide emission will stop. Settle it out and discard, then filter the solution carefully. This is true even if the products are listed before the reactants in the word equation.

Iron(II)-potassium sulfate (K2Fe(SO4)2) • However, complex equations that contain parentheses to describe the order of operations are very hard to understand as word equations. Iron(III) chloride (FeCl3) •
Add cold diluted acid solution to the flask, then add iron pieces, shavings or powder and stir it until gas emission will stop. Iron(II) sulfate (FeSO4) • Therefore tin must be above lead but below iron in the reactivity series. I suspect you want the symbol of each but if not explain what you mean by word equation. Iron(II) citrate (FeHC3H5O(COO)3) •
Usually in these equations two statements are set to be equal to each other. The large amount of poorly soluble precipitate will form. The chemical reaction 2 H2(g) + O2(g) → 2 H2O(g) would be expressed as: hydrogen gas + oxygen gas → steamAs a word equation or as "Hydrogen and oxygen react to form water" or "Water is made by reacting hydrogen and oxygen.". Iron(II)-ammonium sulfate ((NH4)2Fe(SO4)2) • While a word equation doesn't ordinarily include numbers or symbols (Example: You wouldn't say "Two H two and one O two makes two H two O", sometimes it is necessary to use a number to indicate the oxidation state of a reactant so that a person writing a chemical equation can do it correctly.
