identify the reactants and products in any type of snucongo.orgical reaction. Transform word equations right into snucongo.orgical equations. Usage the typical symbols, \(\left( s \right)\), \(\left( together \right)\), \(\left( g \right)\), \(\left( aq \right)\), and also \(\rightarrow\) accordingly when writing a snucongo.orgical reaction.

You are watching: Which equation represents the reaction of sulfur with oxygen to form sulfur trioxide


The burning of fossil fuels outcomes in the formation of carbon dioxide, a greenhouse gas, and also other pollutants. This is an instance of snucongo.orgical change, in which new substances are formed.In order because that this come occur, the snucongo.orgical binding of the substances break, and also the atoms that write them separate and rearrange themselves into new substances with brand-new snucongo.orgical bonds. Once this procedure occurs, we speak to it a snucongo.orgical reaction. A snucongo.orgical reaction is the process in which one or an ext substances are readjusted into one or much more new substances.


Reactants and Products

To explain a snucongo.orgical reaction, we require to show what building material are current at the beginning and also what building material are present at the end. The substances the are present at the start are called reactants and the substances current at the finish are referred to as products.


Writing snucongo.orgical Equations

When sulfur dioxide is added to oxygen, sulfur trioxide is produced. Sulfur dioxide and also oxygen, \(\ceSO_2 + \ceO_2\), space reactants and sulfur trioxide, \(\ceSO_3\), is the product.

\< \underbrace\ce2 SO2(g) + O2(g) _\textReactants \rightarrow \underbrace\ce2SO3(g)_\textProducts \nonumber\>

In snucongo.orgical reactions, the reactants are found prior to the price "\(\rightarrow\)" and the products are discovered after the prize "\(\rightarrow\)". The general equation because that a reaction is:

\<\textReactants \rightarrow \textProducts \nonumber\>

There are a few special icons that we require to understand in order to "talk" in snucongo.orgical shorthand. In the table listed below is the an overview of the significant symbols supplied in snucongo.orgical equations. Table \(\PageIndex1\) mirrors a listing the symbols used in snucongo.orgical equations.

Table \(\PageIndex1\): Symbols used in snucongo.orgical Equations SymbolDescriptionSymbolDescription
\(+\) used to separate multiple reactants or products \(\left( s \right)\) reactant or product in the hard state
\(\rightarrow\) yield sign; separates reaction from products \(\left( together \right)\) reactant or product in the liquid state
\(\rightleftharpoons\) replaces the yield sign for reversible reactions that reach equilibrium \(\left( g \right)\) reactant or product in the gas state
\(\overset\cePt\rightarrow\) formula written above the arrowhead is supplied as a catalyst in the reaction \(\left( aq \right)\) reactant or product in an aqueous solution (dissolved in water)
\(\overset\Delta\rightarrow\) triangle indicates that the reaction is being heated

snucongo.orgists have actually a an option of methods for explicate a snucongo.orgical reaction.

1. Girlfriend candraw a photo of the snucongo.orgical reaction showing the submicroscopic particles.

*

2. You canwrite a indigenous equation because that the snucongo.orgical reaction:"Two molecule of hydrogen gas react with one molecule the oxygen gas to create two molecule of water vapor."

3. Girlfriend canwrite the equation through snucongo.orgical symbols

\<2 \ceH_2 \left( g \right) + \ceO_2 \left( g \right) \rightarrow 2 \ceH_2O \left( g \right)\>

In the symbolic equation, snucongo.orgical formulas are used rather of snucongo.orgical names for reactants and also products, while symbols are used to indicate the phase of every substance.

To turn word equations into symbolic equations, we should follow the given steps:

identify the reactants and products. This will assist you know whichsymbols walk on every side the the arrow and where the \(+\) indicators go. Create the exactly formulas for every compounds. Sometimes a reactant or product is only an facet (like hydrogen gas or oxygen gas). There space seven elements that are thought about diatomic, meaning that lock are always found in pairs in nature. They incorporate those elements noted in the table. Table \(\PageIndex1\): Diatomic ElementsElement NameFormula
