The chemical equation is:SF4 + 2 H2O = SO2 + 4 HF
What equation show exothermic reaction?
An exothermic reaction is represented by an equation in which the products have lower energy than the reactants. This is typically indicated by the release of heat as a product in the reaction. For example: A + B → C + heat.
What is chemical equation when a strong acid is added to a buffer solution containing NaF and HF?
When a strong acid is added to a buffer solution containing NaF and HF, the strong acid will react with the weak base (F-) to form HF. The buffer solution will resist changes in pH by the common ion effect, maintaining the solution's acidity around the initial pH of the buffer. The chemical equation can be written as H+ + F- ↔ HF.
What is the net ionic equation for the reaction 1 hf and mgcl2 2 hf and nh4br?
The net ionic equation for the reaction of 1HF and MGCl2, with 2HF and NHbR, would be approximately 2GCF. This can fluctuate a bit, but will wholly depend on if the NHbR changes at all.
How many grams of SnF2 are produced from the reaction of 30-g of HF?
To calculate the grams of SnF2 produced, you need to first determine the moles of HF using the molar mass of HF. Then use the mole ratio between HF and SnF2 from the balanced chemical equation to find the moles of SnF2 produced. Finally, convert the moles of SnF2 to grams using the molar mass of SnF2.
Derive an equation that relates wavelength and energy?
The energy of a photon (E) is directly proportional to its frequency (f) through the equation E = hf, where h is the Planck constant. The frequency of a wave is inversely proportional to its wavelength (λ) through the equation f = c/λ, where c is the speed of light. Combining these two equations gives the equation E = hc/λ, which relates energy and wavelength.

What is the equation for the acid dissociation constant Ka od HF?
The equation for the acid dissociation constant Ka of hydrofluoric acid (HF) is Ka = [H+][F-] / [HF], where [H+] is the concentration of hydronium ions, [F-] is the concentration of fluoride ions, and [HF] is the concentration of hydrofluoric acid.
What is the equation for the acid dissociation constant of HF?
The acid dissociation constant (Ka) of HF (hydrofluoric acid) is given by the equation: Ka = [H+][F-] / [HF], where [H+] is the concentration of hydrogen ions, [F-] is the concentration of fluoride ions, and [HF] is the concentration of hydrofluoric acid in solution.
Which equation was used by Albert Einstein to explain the photoelectric effect?
Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.

Which eqution would you use to calculate the energy of photon?
You would use the equation E=hf, where E represents the energy of the photon, h is Planck's constant, and f is the frequency of the photon.
What determines the energy of an electromagnetic wave?
The energy of an electromagnetic wave is determined by its frequency. The higher the frequency of the wave, the higher the energy it carries. This relationship is described by the equation E=hf, where E is energy, h is the Planck constant, and f is frequency.
What number should be placed in front of HF to balance this chemical equation?
To balance the chemical equation HF, you would need to place the coefficient "2" in front of HF. This would give you 2HF on both sides, creating a balanced equation: 2HF = 2HF.
