Can gas laws be used with balanced chemical equations to calculate the amount of a gaseous reactant or product in a reaction?
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 .
What else can I help you with?
If 100 g of CuS and 56 g of O2 are available which is the limiting reactant?
To determine the limiting reactant, first calculate the moles of each reactant by dividing the given mass by their respective molar masses. Then, determine the mole ratio between CuS and O2 in the balanced chemical equation. The reactant that produces fewer moles of product based on this ratio is the limiting reactant.
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!
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.
How many oxygen atoms are in the reactant aluminum phosphate in the balanced reaction below?
The reactant aluminum phosphate has a chemical formula AlPO4. There are 4 oxygen atoms in one molecule of aluminum phosphate.
What mass of so2 is produced from the reaction of 31.5g of s8 and 8.65g of o2?
First, balance the chemical equation: S8 + 8 O2 -> 8 SO2. Calculate the moles of each reactant using their molar masses. The limiting reactant is the one that produces the least amount of SO2, which is S8 in this case. Therefore, use the stoichiometry of the balanced equation to calculate the mass of SO2 produced from 31.5g of S8.
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
Why are chemical equations always balanced?
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
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.
Why does chemical reaction have many possible balanced equations?
Chemical reactions can have many possible balanced equations because there are various ways in which the reactant molecules can combine to form different products. Each combination may result in a different balanced equation depending on the stoichiometry of the reaction. Additionally, different conditions, such as temperature and pressure, can also affect the outcome of the reaction, resulting in different balanced equations.
what reactant has the smallest coefficient in a balanced chemical equation?
The reactant with the smallest coefficient in a balanced chemical equation is considered the limiting reactant because it limits the amount of product that can be formed.
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.
Why does the law of conservation of mass dictate the chemical equations be p why does the law of conservation of mass dictate the chemical equations be balanced?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, only rearranged. In order to adhere to this law, chemical equations must be balanced to ensure that the same number of each type of atom is present on both the reactant and product sides of the equation. This balancing of chemical equations ensures that mass is conserved throughout the reaction.
What do the major types of stoichiometry problems include?
The major types of stoichiometry problems include mass-mass, volume-volume, mass-volume, and limiting reactant problems. Each type involves using balanced chemical equations to calculate the quantities of reactants and products involved in a chemical reaction.
Equations show each side is equal as far as the number of atoms and molecules?
In a balanced chemical equation, the number of atoms of each element on both the reactant and product sides are equal, ensuring the law of conservation of mass is satisfied. This balance signifies that no atoms are created or destroyed during a chemical reaction, but instead rearranged.
Chemical equations must be balanced because of the?
law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing chemical equations ensures that the number of atoms of each element is the same on both the reactant and product sides of the equation, maintaining mass equilibrium.
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.
