How is hess law used to measure enthalpy of a desired reaction?
... Intermediate equations with known enthalpies are added together.
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.
A student performed the reaction for the production of acetaminophen exaclty as described in this experiment and obtained 0.86g of the desired product what is the percent yeid for this reaction?
wwwwwwwwwwwwwwwwww
How do you calculate the atom economy?
Atom economy or atom utilization is simply the Mr or molecular weight of desired product formed divided by the Mr of all the reactants. Say we have a reaction A + B -----> C C + D ------> E AU = (Mr of E/(Mr of A + B + C)) x 100
How can a chemical reaction shift toward the desired direction?
You can make it shift, by Le Chatliers principle. Or. By Reaction Quotient method and comparing it against the Equilibrium constant.
What does Hess's law say about the enthalpy of a reaction?
The enthalpy of a reaction does not depend on the reactant path taken.

What is the fomula of chemical energy?
Assuming chemical energy means the enthalpy change (measured in joules), there are several methods to calculate chemical energy, although there is no one 'formula'. The simplest way is to calculate the bond energies between the atoms in the molecules and subract the total initial energy from the total final energy. If bond energies aren't provided, more complex methods are required. If you're looking for the change in enthalpy in the reaction A --> D, and are given the changes in enthalpy for A --> B, B --> C, and C --> D, then adding the enthalpy changes for the given reactions will give you the desired enthalpy change.
What does Hess's law make it possible for you to do?
Hess's law makes it possible to determine the overall enthalpy change for a chemical reaction by combining the enthalpy changes of multiple indirect reactions that add up to the desired reaction. This allows the prediction and calculation of the energy changes in chemical reactions, even if direct measurement of the reaction is not possible.
What is the square root of 444?

What is the formula to calculate the diameter of a string to get the desired Hz if you know the wavelength?
There is no such formula.
Why you use 455kHz frequency as an intermediate frequency in communication?
The intermediate frequency in the superheterodyne receiver is chosen as the desired compromise between sensitivity and selectivity. 455kHz is used in AM broadcast applications, while 10.7mHz is used for FM. The IF stage is tuned for a steep skirt passband at that frequency, allowing only the desired heterodyned (shifted) input signal to make it through to the demodulator.
