1 mol of silver means 6.02 x 10²³ Ag atoms
number of moles of silver
= 2.408 × 10²⁴ Ag atoms x <u> 1 mol Ag </u>
6.02 x 10²³ Ag atoms
= 0.4 x 10
<u>= 4 moles</u> Ag
<u>4 moles of silver</u> are equivalent to 2.408 × 10²⁴ atoms
Solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the liquid and is inversely proportional to the temperature.
So, the solubility of <u>gas </u>in water decreases as the temperature increases.
To calculate the wavelength of this radiation if the SI unit of time is the second, which is defined as 9,192,631,770 cycles of radiation associated with a certain emission process in the cesium atom, the wavelength is one cycle of radiation, and therefore the wavelength is 1/9192631770
X rays are the correct answer :)
Answer:
[He]2p6
Explanation:
Fluorine has an atomoc number of 9 which means 9 electrons with the electon configuration:[He]2p5,However,when it becomes Fluoride ion,it gains one electron to complete its outermost shell to obtain an octet configuration and becomes [He]2p6.
