Create Chemistry Equations and Diagrams in Word.
Chemical equations can also be used to describe physical changes. We will see examples of this soon.. Write a chemical equation to express the fact that sodium metal and chlorine gas react to make solid sodium chloride. Make sure the equation satisfies the law of conservation of matter. Write an equation expressing the fact that hydrogen gas and fluorine gas react to make gaseous hydrogen.
Write word equations for the reactions in this specification. Edexcel Chemistry. Formulae, equations and hazards. 0.2 Write word equations; Topic 3 - Chemical changes. Acids. 3.11 Explain the general reactions of aqueous solutions of acids with: metals, metal oxides, metal hydroxides, metal carbonates to produce salts; Edexcel Combined science.
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, remembering that both elemental hydrogen and chlorine are diatomic.
To writing the unbalancedequation, first write the chemical formulas of reactants on the lefthad side of the equation and then write the chemical formulas ofproducts obtained from the reaction on the write hand side of theequation. Finally put the arrow between the reactants and productsto show the direction of the reaction but arrows are facing in bothdirections if the reaction at equilibrium.
For each of the following problems, write complete chemical equations to describe the chemical process taking place. Balance the equations. 1) When lithium hydroxide pellets are added to a solution of sulfuric acid (H2SO4), lithium sulfate and water are formed. 2) Magnesium reacts with sodium fluoride to produce magnesium fluoride and elemental sodium. 3) If a copper coil is placed into a.
Chemical reactions can be written as equations. However, most chemical reactions in biology work in opposition to their counterpart reaction. This is called chemical equilibrium.
