When we represent a chemical reaction in terms of words, we write a word equation. For example, when hydrogen gas reacts with oxygen gas to form water, we can write a word equation for the reaction as follows: hydrogen + oxygen→ water. To the left of the arrow, we have the ''before'' situation.
Generally speaking, converting a word problem into an equation involves reading through the problem and setting up word equations — that is, equations that contain words as well as nuers.. Most word problems give you information about nuers, telling you exactly how much, how many, how fast, how big, and so forth.

Write a balanced equation to represent the dissociation of each of the following ionic compounds. of water is maximum at 4 degree celsius explain The _____ of a chemical company can be obtained directly from the balance sheet as the difference between current assets and current liabilities The ksp of agcl is 10 10 find e for ag if ag rod is
The first step to balance the equation is to write down the chemical formula of reactants that are listed on the left side of the chemical equation. After this, you can list down the products on the right hand side of the chemical equation. There is an arrow between the sides, signaling the direction the reaction is …
Writing Balanced Equations for Coination and . Decomposition Reactions. Write balanced chemical equations for the following reactions: (a) Solid mercury(II) sulfide decomposes into its component elements when heated. (b) The surface of aluminum metal undergoes a coination reaction with oxygen in the air. Answer: (a) HgS(s) →Hg(l) + S(s
Jan 14, 2009· My teacher is pretty strict about details, and Im working on an assignment about writing/balancing chemical reactions. The question is: When heated, calcium carbonate decomposes to form calcium oxide and carbon dioxide. Write the equation for this reaction. He never really mentioned how to write
Write and balance chemical equations in molecular, total ionic, and net ionic formats. An earlier chapter of this text introduced the use of element syols to represent individual atoms. When atoms gain or lose electrons to yield ions, or coine with other atoms to form molecules, their syols are modified or coined to generate chemical
Iron is a metal. When we represent it in a balanced chemical equation, we write only \(\text{Fe}\). Sulfur occurs as \(\text{S}_{8}\) but we write only the empirical formula: \(\text{S}\). We do this for all network structures. Writing formulae like this represents one unit of the compound or network structure.
Photosynthesis can be represented using a chemical equation. The overall balanced equation is 6CO 2 + 6H 2 O -----> C 6 H 12 O 6 + 6O 2 Sunlight energy . Where: CO 2 = carbon dioxide H 2 O = water Light energy is required
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored.

Write a balanced chemical equation and state the reaction type for each of the following reactions: a.) nitrogen gas reacts with hydrogen gas forming ammonia (NH3) b.) carbonic acid breaks down to form carbon dioxide gas and water c.) aluminum foil reacts with copper II chloride solution to produce aluminum chloride solution and copper metal d.) aluminum chloride reacts with lead II nitrate to
A balanced equation for reaction of ammonia with oxygen to form nitrogen monoxide and water is 4 NH3 + 5 O2 -> 4 NO + 6 H2O.
Example 1. Write and balance the chemical equation for each given chemical reaction. Hydrogen and chlorine react to make HCl. Ethane, C 2 H 6, reacts with oxygen to make carbon dioxide and water.; Solution. Let us start by simply writing a chemical equation in terms of the formulas of the substances, remeering that both elemental hydrogen and chlorine are diatomic:
Dec 15, 2014· Sugars are a white crystalline group of soluble carbohydrates that are very sweet-tasting in nature. Sugar molecules include glucose, fructose, sucrose, lactose, maltose, and galactose, classified into two groups: monosaccharides and disaccharides. Glucose - C_6H_12O_6 - is a monosaccharide and its coustion reaction is C_6H_12O_6 + 9O_2 -> 6CO_2 + 6H_2O Sucrose (C_12H_22O_11) - …
