It usually works.
If you know what the reactants are, then you can calculate the total mass of the reaction system, as you can detecte the volume of the gas, then you can calculate the mass or number of moles of the gas basing on the atmospheric pressure and temperature, the information may lead you to the answer.
For example, if you completely combuse CH4 in a rigid container, you can detecte the products, CO2 and H2O. Then you can predict the entire equation :
CH4+2O2=CO2+2H2O .

∙ 12y agoYes, if the gases are sufficiently close to ideal gases for the ideal gas law to apply, or a more accurate law is known for the specific gas(es) in question is known, along with the temperature and pressure of the reaction. The number of moles of gas produced by reacting or producing a gas in a known number of moles is calculated in the same manner as for non gaseous reactants and products, and the number of moles can be converted to a volume by using the appropriate gas law.

After a chemical reaction starts when will a chemical reaction end?
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
What information in a balanced chemical equation shows how many moles of a reactant are involved in the reaction?
The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.
How many oxygen atoms are in the reactant aluminum phosphate in the balanced reaction below?
there are 8
If one knows the mass and molar mass of reactant A and the molar mass of product D in a chemical reaction one can determine the mass of product D produced by using the?
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
Elements or compounds that enter into a chemical reaction?
reactant
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
How can balenced equations be used to calculate the volume of gases formed in chemical reactions?
The coefficients in a balanced chemical equation shows how many moles of each reactant is needed in order for a reaction to take place. After determining how many moles of each reactant is required, you would convert it to grams to calculate how much of each reactant is needed to form a given amount of product in a chemical reaction.
Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
What information In a balanced chemical equation shows how many moles of a reactant are involved in the reactant?
In a balanced chemical equation the number of molecules or atoms are specified.
What is the balanced equation for IronIII Chloride?
The formula for iron(III) chloride is FeCl3. Equations are only for chemical reactions and they show what reactant(s) form what product(s).
What information in a balanced chemical equation shows how many moles of a reactant are involed in the reaction?
The number before the chemical formula of the reactant.
What gets written into a chemical reaction when it is balanced?
In a complete and correctly balanced chemical equation you will have the coefficients for each reactant and product indicating the mole ratios as well as the phases of each reactant and product.
Why is it essential to use balanced chemical equations when determining the quantity of a product fo?
It should represent a true chemical change. It should be balance it should be molecular all the reactant and product must be written in term of there respective chemical formula.
what reactant has the smallest coefficient in a balanced chemical equation?
It depends on the equation.
How can one tell how much reactant will be used in a reaction?
from a balanced chemical equation
What does a balanced chemical equation convey to a chemist?
A balanced equation indicates the chemical formulas for the substances involved in the reaction and the number of molecules or moles of each substance in the reaction. This enables a chemist to calculate the amount of each reactant needed to produce a desired quantity of product.
