Why does an unbalanced equation not describe a reaction fully?
No balance=No conservation of mass So, you would not know how much to add from this reactant and maybe no reaction will occur.
How do physical and chemical changes affect mass?
law of consevation of mass states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction
In any chemical reaction the quantities that are preserved are?
In any chemical reaction the quantities that are conserved are mass and number of atoms. After the correct formula for a reactant in an equation has been written, the formula should not be changed.
Which is the limiting reactant when masses of reactants are same?
You must first convert the mass of each reactant into moles of each reactant. Having the same mass does not mean that the amount of each reactant is the same, because each reactant has its own unique molar mass. Refer to the related link below for instructions on determining limiting reactants, also called limiting reagents.
Why is iron is a limiting reactant?
It is unique from reaction to reaction. If it is the more basic question that I think it might be, you always look at the moles of each reactant and what ratio they react. If they react 1:1, then the reactant with less moles will be consumed first, and therefore quenches that particular reaction naturally
What is the reactant of 10.0 grams of total mass What is the chemical reaction?
It is possible to have ten grams of anything. Specifying the total weight tells you nothing about which reactant you have or what reaction it will undergo.
Why amount of reactant and product do not change in a reversible reaction?
This is the law of mass conservation.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What information do you need to predict the mass of a reactant or product in a chemical reaction?
To predict the mass of a reactant or product in a chemical reaction, you would need the balanced chemical equation for the reaction, as it provides the stoichiometric ratio between the reactants and products. Additionally, you would need the molar mass of the specific substance you are interested in. With this information, you can calculate the mass using stoichiometry and molar ratios.
What is is the principle of conservation of mass?
The amount of matter involved in a chemical reaction does not change. The total mass of the reactant must equal the total mass of the products.
What is the Decreasing the particle size of reactants?
the bigger the particle the slower it will react. the smaller the particle the faster it will react
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!
Why does an unbalanced equation not describe a reaction fully?
No balance=No conservation of mass So, you would not know how much to add from this reactant and maybe no reaction will occur.
What is the limiting reactant reagent and what is excess reagent in recrystallization?
The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.
What determines the coefficient ratio used to predict the amount of product produced from any given amount of reactant?
The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)
How does the mass of a melting solid affect the closed systems mass?
It doesnt. Law of Conservation of Mass.
How do physical and chemical changes affect mass?
law of consevation of mass states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction
