Answer:
which elements??? more info please
Answer:
Wavelength = 9.4×10⁹ m
Explanation:
Given data:
Frequency of radiation = 3.2×10⁻² Hz
Wavelength of radiation = ?
Solution:
Formula:
Speed of light = frequency ×wavelength
Speed of light = 3×10⁸m/s
Now we will put the values in formula.
3×10⁸m/s = 3.2×10⁻² Hz × wavelength
Wavelength = 3×10⁸m/s /3.2×10⁻² s⁻¹
Wavelength = 0.94×10¹⁰ m
Wavelength = 9.4×10⁹ m
In its elemental form, Iodine is a diatomic molecule in the gas phase. In the periodic table, Iodine is just right beside Xenon which is a stable element because it has no extra electrons. Thus, to conform to stability, Iodine must have to gain one more electron. That's why in its ionic form, its formula is I⁻. The reaction would be
I₂ → 2 I⁻
To achieve the Law of Definite Proportions from Dalton's Atomic Theory, we must balance the reaction. So in every neutral Iodine atom, 2 Iodide ions are formed.
There are 7.0 x 10^22 C2H5OH molecules in the sample.
Ethanol (also referred to as ethyl alcohol, grain alcohol, consuming alcohol, or actually alcohol) is an organic chemical compound. It is simple alcohol with the chemical system C2H6O. Its method can be also written as CH3−CH2−OH or C2H5OH (an ethyl team linked to a hydroxyl group) and is regularly abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with an attribute wine-like odor and pungent taste. It is a psychoactive drug, a leisure drug, and an energetic ingredient in alcoholic drinks.
