Percent yield =(Experimental)/(Theoretical) x 100 = 2.55 g/ 2.78 g x 100 = 91.7%
Answer:
v = 16 m/s
Explanation:
Given that,
Distance, d = 400 m
Time taken, t = 25 s
We need to find the speed of the horse. Speed is equal to distance covered divided by time taken. So,
So, the speed of the horse is 16 m/s.
Answer is: the maximum wavelength of light is 7.34 × 10⁻⁷ m.
E= 163 kJ/mol; bond energy of one mole of nitrogen.
E = 163000 J/mol ÷ 6.022·10²³ 1/mol.
E = 2.707·10⁻¹⁹ J; bond energy per molecule.
E = h·c/λ.
c = 3.00 × 10⁸ m/s; light speed.
h = 6.62607004·10⁻³⁴ J·s; Planck constant.
λ(photon) = h·c/E.
λ(photon) = 6.62607004·10⁻³⁴ J·s · 3.00 × 10⁸ m/s ÷ 2.707·10⁻¹⁹ J.
λ(photon) = 7.34 × 10⁻⁷ m.
λ(photon) = 734 nm.
