The number of elements and compounds reacting is a way to predict possible reaction type and possible products. An example is the reactants in a combustion reaction are oxygen and usually a hydrocarbon; and the products are usually carbon dioxide and water, and in a double-replacement reaction the reactants are two ionic compounds and two new compounds are the products.
Processes and methods used to predict products if reactants are known is used by balancing chemical equations. Balancing equations is a two- step process, where as first you have to write the skeleton equation and then use the coefficients to balance the equation so that it obeys the law of conservation of mass. In every balanced equation, each side of the equation has the same number of atoms of each element, but sometimes you don't have to balance equations because a skeleton equation may already be balanced. For example, carbon burns in the presence of oxygen to produce carbon dioxide. This is already balanced because one carbon atom and two oxygen atoms are on each side of the equation.
I agree with Fanica.A thought process that could be used to predict products are balancing equations.During balancing equations the reactants are shown, and you have to use a thought process in order to show the reactancts. Balancing equations are simply equations for chemical reactions. in which the number of atoms for each element in the reaction and the total charge are the same in the product. Basically the mass and the charge are balanced on both sides of the reaction.In doing this you will see both the reactants and the products.
every ones post is agreable because this is when two or more elements are combinde similar two the balanceing equations that dr k tought my 5th perieod class. i also think that the procces of balancing equation has somthing to deal with this because of the several different ways of balancing an equatin like single replacements because a metal has to replace another atom with a positive charge.
i agree with shartel and fanica.to predict product if reactants are shown you must use balancing equations.An equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction. An example would be Combustion reactions, always involve burning. In this case, oxygen is a reactant. If the other reactant is a hydrocarbon,then the products are always carbon dioxide and water.
One method for trying to predict products if reactants are first knowing if your compounds are ionic or covalent.which should help you know how the element will react.
You can't use what type of chemical reaction it is because you don't know your products. For elements simply knowing if it is a cation or a anoion should help you also decide how it will react, when placed with other compounds or elements. Honestly, i did not find any evdience for these on the internet. I just used what i already know about elements and compounds.
One way to know what atoms are in the product by just having the reactant is that the atoms in the product are the same atoms that were in the reactants, just rearranged. Another way of finding out the products if reactants are already known is by using the method of balncing equations. This is a tow-step process. First, you must write the skeleton equation. then you use coefficients to balance the equation so that it obeys the law of conservation of mass.
Ok away to predict a product if the reactants are known is to first write down the cations and anions present in each of the reactants and then swap the ions to build the products. Then you would label the products as a liquid, solid, aqueous, or gas. Lastly, you would observe to see if the reaction does occur and then balance the equation.
i would have to say that a reactant will disappear when chemical change occurs.and the product will show as the chemical change happens. this would make it possible to predict the equation if are able to see the patteren.

ReplyDeleteWhat it would be if you have an element and a compound as reactants?

Makeda, information for this question is right in the text book.
ReplyDeleteFanica, Shartel, Victory, Tykeria,
ReplyDeleteHow balancing equations helps us predict products if reactants are known.
so was my information/ theory correct? or even on the right track?

ReplyDeleteMakeda, If you know the nature of reactants as ionic or covalent, this may help you some times it does help you to predict products, not always.
