A good way to think about a chemical reaction is the process of baking cookies. You mix the ingredients together flour, butter, salt, sugar, and eggsbake it, and see that it changes into something new: cookies! In chemistry terms the equation is the recipe, the ingredients are "reactants," and the cookies are "products. The chemiacl represents the reaction or change taking place.

To write the equations there are a number of important naming rules that you need to know. If you want to write a chemial equation, start by writing the chemical formulas of each reactant. Use the prefixes, such as mono- di- tri- and tetra- to figure out chemicwl number of atoms w for each element, and write this number as a subscript for each element.

For example, dihydrogen monoxide would be more easily written as H2O. Once you have the names of jake reactants written, add a plus in between them and draw an arrow to indicate the product of the reactants.

Covalent compounds are written out as molecular formulas due to the fact that each compound is a distinct, separate molecule. Write the chemical symbol for the first element.

When a compound has been written out, you must identify the elements and know their chemical symbols. Use the periodic table to find the chemical symbol for the element. Too first element is nitrogen and the chemical symbol for nitrogen is N. Add the number of atoms as a subscript. To identify the number of atoms present for each element, you simply need to look at the prefix of the element.

Memorizing the Greek prefixes will help you to be able to what is a streak plate made of chemical formulas quickly without looking anything up.

Write dinitrogen as N 2. Write the chemical symbol for the second element. The second element is fluorine. The chemical symbol for fluorine is F. Add the number of atoms present as a subscript. As you did with the first element, identify the number of atoms present in the second too by reading the prefix.

Using this prefix, write the number of atoms as a subscript to the right cuemical the chemical symbol. Write hexafluoride as F 6. The final chemical formula for dinitrogen hexafluoride is N 2 F 6. Practice with some examples.

When first learning chemistry, there is a lot of memorization involved. It is kind of like learning a new language. The more examples you practice with, the easier it will be to decipher chemical formulas in the future and learn the t of chemistry. Part 2 of Identify the chemical symbols for the cations and anions. All chemicals have what you can call a first and last name. The first name is the cation positive ion while the last name is the anion negative ion.

Unlike covalent compounds, Greek prefixes are not used to indicate the number of atoms of each element. You have to balance the charges of the elements to determine the atoms. For example: Lithium oxide is Li 2 O. Recognize polyatomic ions. Sometimes the cation or anion is a polyatomic ion.

These are molecules that have two or more atoms with ionic groups. The rest of xhemical polyatomic ions have negative charges ranging from -1 to Determine the valence charge of each element. The valence charge can be determined by looking at the position of the element on the periodic table. Transition elements will have Roman numerals in parentheses to indicate what is na2co3 used for charge. Mae 17 elements are Group 16 elements are Group 15 elements are Remember, when working with polyatomic ions, use the charge of the complete polyatomic ion, rather than the individual ions.

Balance the positive and negative charges of the ions. Once you maek identified the charge of each element or polyatomic ionyou s use these charges to determine the number of atoms present of each element. You want the charge of the compound to equal zero so you will add atoms to balance the charges. Oxygen is a group 16 element and has a 2- charge.

In order to balance the 2- charge che,ical the oxygen, you need 2 atoms of lithium; therefore, the chemical formula of lithium oxide is Li 2 O.

The best way to learn formula writing is to practice with lots of examples. Use examples in your chemistry book or look for practice sets online. Do as many as you can until you feel comfortable writing chemical formulas.

Calcium Nitride: Symbol for calcium is Ca and symbol of nitrogen is N. Nitrogen is a group 15 element and has a charge of Phosphate has a 3- charge.

Part 3 of Identify all of the cations and anions in the reactants. In a basic double replacement equation you will have 2 cations and 2 anions. You also chemmical to determine the charges of each ion.

The anions are NO 3 1- and Cl Switch the ions to build the products. Once you have identified all of the ions and their charges, rearrange them so that the first cation is now paired with the second anion, and the second cation is how to make paper clip rings paired with the first anion. Write the full equation. After writing the products that will form in what does android means in phones equation, you chhemical write the whole equation with both products and reactants.

Keep the howw on x left side of the equation chemicl write the new products on the right side with a plus sign between them. Balance the equation. Cnemical you have written the equation and have all of the fo and reactants you need to make sure everything is balanced.

An equation is balanced only when you have the same number of atoms of every element present on both sides. Note the states of matter. There is a designated letter for each state of matter which goes in parentheses.
