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.
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.
In mathematics what is a limiting value?
If the value of a function cannot be determined for any value of the independent variable, then, the value the function seems to be approaching would be its limiting value for that particular value of the independent variable.
What are non -stoichiometric compounds?
The defect which disturb the stoichiometric of the compound is called non-stoichiometric compounds.
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.
Is iron oxide a non stoichiometric compound?
is fe3o4 non stoichiometric
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
What functions do ideal stoichiometric calculations serve?
Ideal Stoichiometric calculations give the theoretical yield of the products of the reaction
Methanol stoichiometric ratio?
6.42
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 is the purpose of a titration?
The purpose of a titration is to find the equivalence point (stoichiometric point) of a solution. At the equivalence point, the moles of the titrant and analyte are equal to one another. At the midpoint of the solution, the pKa value is equal to the pH value.
What are catalytic and stoichiometric reagents?
because the catalytic reagents has higher activiation energy than stoichiometric reagent. NOTE a catalyst speeds up a reaction and is in no way affected during a reaction, a stoichiometric reaction is used up during the reaction
What is a berthollide?
A berthollide is any non-stoichiometric compound.
What is the stoichiometric point of a titration called?
end point
All Stoichiometric calculations begin with a?
Balanced Chemical equation
