How is delta hf related to the delta h of the reaction?
The standard enthalpy change of a reaction (delta H) is related to the standard enthalpy of formation (delta Hf) of the products and reactants involved in the reaction by the equation: delta H = Σ(Products delta Hf) - Σ(Reactants delta Hf). This equation relates the enthalpy change of a reaction to the enthalpies of formation of the substances involved in the reaction.
How to calculate the heat of reaction in a chemical reaction?
To calculate the heat of reaction in a chemical reaction, you can use the formula: H (Hf products) - (Hf reactants), where H is the heat of reaction, Hf is the standard heat of formation, and the symbol means to sum up the values for all products and reactants. This formula helps determine the amount of heat released or absorbed during a chemical reaction.
How does the H reaction relate to the Hf of molecules involved in a reaction?
Hreaction = Hf products - Hf reactants
Why is HF acidic?
Hydrofluoric acid (novanet)
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
How is the H related to the H of a reaction?
The h reaction is the difference between Hf products and Hf reactants - apex

which of the following describes an endothermic reaction?
Hf, products > hf, reactants
What is the chemical reaction of HF and water?
Not a chemical reaction, but the formation of a water solution of hydrofluoric acid.
How are energy and frequency of electromagnetic radiation related?
Energy = hf where h is Planck's Constant and f is the radiation frequency.
What is the Equation by which energy and frequency are related?
Planck's Equation Energy=hf where h is Planck's Constant and f is the frequency.
How is Planck's quantum theory related to the photoelectric effect?
E=hf where f is frequency and h is plank's constant.
