In the reaction ca + f2 caf2 , what should be the coefficient for f2?

1 answer:

6 0

Answer : In the reaction of Ca + $F _{2}$ --->Ca $F _{2}$ , the coefficient of Ca and $F _{2}$ will be the same which will be 1.

Explanation : As per the rules of writing a chemical equation and balancing it properly, the number of elements in reactants side should be equal to the number of elements generated in product side. Hence when we use 1 molecule of Ca and one molecule of $F _{2}$ then it generates 1 molecule of Ca $F _{2}$ .

Calculate the frequency and wavelength for a photon of light with an energy of 3.2x10-19 J.

tamaranim1 [39]

Answer:

wavelength = 6×10⁻⁷m

f = 0.5 ×10¹⁵ Hz

Explanation:

Given data:

Energy of photon = 3.2×10⁻¹⁹ J

Wavelength of photon = ?

Frequency of photon = ?

Solution:

E = h.f

f = frequency

h = planck's constant

E = energy

f = E/h

f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s

f = 0.5 ×10¹⁵ s⁻¹

s⁻¹ = Hz

f = 0.5 ×10¹⁵ Hz

Wavelength:

speed of light = wavelength × frequency

wavelength = speed of light / frequency

wavelength = 3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹

wavelength = 6×10⁻⁷m
