Answer:
λ = 426.7 nm
E = 4.66 x 10⁻¹⁹ J
Explanation:
The equation of frequency is:
f = v / λ
v: velocity
λ: wavelength
λ = v / f
λ = 3 x 10⁸ m.s⁻¹ / 7.03 x 10¹⁴ Hz
λ = 426.7 nm
The energy of a single photon is
E = hf
h: Plank's constant = 6.63 x 10⁻³⁴ m²kgs⁻¹
E = 6.63 x 10⁻³⁴ m²kgs⁻¹ x 7.03 x 10¹⁴ Hz
E = 4.66 x 10⁻¹⁹ J
Answer: It is a Heterogeneous mixture.
The beaker contains a mixture of three solids, namely flour, sugar, and baking soda. These components retain their properties in the mixture and are not chemically combined.
The contents of the beaker can be described as a mixture. A mixture is a combination of two or more substances that are not chemically combined. In this case, the beaker contains flour, sugar, and baking soda. These are solid substances that maintain their own properties in the mixture. They're simply combined in the same space (the beaker), but they are not interacting on a molecular level to form a new substance.
