Balance the chemical equation. In this lesson, we will learn how to write a balanced chemical equation given the word equation. We have more lessons on the rules for balancing chemical equations.
Each element is represented by a different symbol. Write a balanced chemical equation including the state symbols. All these symbols are in the periodic table. Conversion of word equation to chemical equation Example: Lead II nitrate reacts with sodium iodide to create lead II iodide and sodium nitrate.
Sulfur dioxide and oxygen combine to produce sulfur trioxide. When compounds react, they are chemically changed into new compounds. Ammonium nitrate decomposes explosively to form nitrogen, oxygen, and water vapor.
Sodium Chloride solution and insoluble iron II hydroxide are produced. Chemical Equation A chemical equation shows the overall change of reactants to products in a chemical reaction. Convert the chemical names into chemical formulas. Mercury II oxide decomposes to produce mercury and oxygen.
We can use these symbols to show molecules of compounds, and they can show us the ratio of the different elements which combine to form compounds.
Chemical equations combine formulas with other symbols to show what changes takes place. Every chemical change can be communicated symbolically using a chemical equation.

The following table gives the physical states and the state symbols used in chemical equations: Scroll down the page for more examples and solutions.
Phosphorous reacts with oxygen gas to produce diphosphorous pentoxide. In a precipitation reaction, sodium hydroxide solution is mixed with iron II chloride solution.
This table can be used to help you work out the chemical formula of the reactants and products. Identify reactants and products and place them in a word equation. When calcium comes in contact with water, calcium hydroxide and hydrogen gas is produced.
The following table gives the valency of some common ions. Place them based on the chemical equation and write the state symbols. Sodium hydroxide reacts with iron III nitrate to create a precipitate of iron III hydroxide in a solution of sodium nitrate. When hexane C6H24 reacts with oxygen a combustion reaction occurs.

Sometimes, state symbols are required to indicate the physical states of the substances in a chemical reaction.Chemical Reactions Identify Reactants And Products. Showing top 8 worksheets in the category - Chemical Reactions Identify Reactants And Products.
Some of the worksheets displayed are Chemical reactions name, Chemical reactions equations chapter 1, Work writing and balancing chemical reactions, Balancing chemical reactions, Types of chemical. Reactants are chemicals combining to give out product or products.
Thus reactants are written on the left hand side of an equation and products on the right hand side keeping in mind law of conservation of mass that is both the side of the equation follow this. Write the chemical equation for photosynthesis, and indicate the reactants and products of the equation 6CO2+6H2O > C6 H12 O6+6O2 List the pigments of photosynthesis, the colors of white light they absorb, and the colors of light they reflect.
Chemical equation for a chemical reaction is written as follows: Identify the reactants and the products of the chemical reaction.
Write down the formulae or symbols of the reactants only the left hand side with a sign of plus (+) between them. Write a balanced chemical equation including the state symbols.
Solution: Step 1: Identify reactants and products and place them in a word equation. sodium hydroxide + iron(II) chloride → sodium chloride + iron(II) hydroxide. Step 2: Convert the chemical names into chemical formulas. Place them based on the chemical equation and write the state. Write the unbalanced equation.
Chemical formulas of reactants are listed on the lefthand side of the equation. Products are listed on the righthand side of the equation. Reactants and products are separated by putting an arrow between them to show the direction of the reaction.
Reactions at equilibrium will have arrows facing both directions.Download
