Why is it essential to use balance equations in solving stoichiometric problems?
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
Is it true if the sum of the stoichiometric coefficients on one side of the equation will always equal the sum of the stoichiometric coefficients on the other side?
C6H12O6 + 6O2 -> 6CO2 + 6H2O 7 ( implied one in front of the carbohydrate glucose ) does not equal 12, so not true Only the sum of the atoms must be equal.
When you write an equilibrium constant expression how do you decide what goes on in the numerator and in the denominator?
In an equilibrium constant expression, the numerator consists of the concentrations (or partial pressures) of the products raised to the power of their stoichiometric coefficients from the balanced chemical equation. Conversely, the denominator contains the concentrations (or partial pressures) of the reactants, also raised to the power of their respective stoichiometric coefficients. This arrangement reflects the principle of the law of mass action, which states that at equilibrium, the ratio of product concentrations to reactant concentrations remains constant at a given temperature.
What is the difference between a face value and a value in 3508?
The face value of 3 is 3: the value of 3 is 3000The face value of 5 is 5: the value of 5 is 500The face value of 3 is 3: the value of 3 is 3000The face value of 5 is 5: the value of 5 is 500The face value of 3 is 3: the value of 3 is 3000The face value of 5 is 5: the value of 5 is 500The face value of 3 is 3: the value of 3 is 3000The face value of 5 is 5: the value of 5 is 500
What if actual value - measured value is negative?
Then the measured value is larger than the actual value.
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
What is the difference between stoichiometric and non stoichiometric solids?
Non-stoichiometric compounds are chemical compounds with an elemental composition that cannot be represented by a ratio of well-defined natural numbers.Stoichiometric compounds are compounds in which atoms are combined in exact whole-number ratios.
What functions do ideal stoichiometric calculations serve?
Ideal Stoichiometric calculations give the theoretical yield of the products of the reaction
What is the stoichiometric point of a titration called?
The stoichiometric point of a titration is called the equivalence point. At this point, the moles of acid and base have reacted in exact stoichiometric proportions, resulting in complete neutralization.
What is the equivalence or stoichiometric point?
At the stoichiometric point of a titration, the total amount (in moles) of OH- ions that have been added as a titrant is exactly equal to the amount of H3O+ ions initially present in the beaker.The measured pH of at the stoichiometric point of a strong acid-strong base titration is expected to be that of pure water i.e. pH = 7. In practice, attainment of the stoichiometric point will be marked by sudden sharp rise in pH from a value significantly below 7 to a value significantly above 7.
What are non -stoichiometric compounds?
Non-stoichiometric compounds are compounds that do not have a fixed ratio of elements in their chemical formula. This means that the ratio of elements in the compound can vary within certain limits. This can be due to factors such as defects in the crystal lattice or the presence of excess or deficient elements in the compound.
Is iron oxide a non stoichiometric compound?
Yes, iron oxide can exist as a non-stoichiometric compound. This means that the ratio of iron to oxygen atoms in the compound is not a whole number and can vary. Examples include magnetite (Fe3O4) and wüstite (FeO).
What is a berthollide?
A berthollide is any non-stoichiometric compound.
What is stoichiometric relations?
How I understand it, it is how the written chemical formula is balanced.
What is an example of the law of definite proportion?
All stoichiometric compounds.
What are catalytic and stoichiometric reagents?
Catalytic reagents are used in small amounts to increase the rate of a reaction without being consumed. Stoichiometric reagents are used in precise amounts based on the reaction stoichiometry and are fully consumed during the reaction.
What is the importance of the stoichiometric ratio?
if there isnt any stoichiometric ratios batman wont be able to save robin from the penguin coz he didny huv any money left in the bat bank
