Solubility<span> is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It has units of grams of the substance per grams of solvent. We calculate the mass as follows:
311 g AgNO3 / 100 g water (350 g water) = 1088.5 g AgNO3
It can be rounded of to 1100 g of AgNO3. Therefore, option B is the correct answer.</span>
Answer:
Valency of Chlorine is 1 because it needs 1 electron to complete its octet (a shell of eight electrons). Valency is defined as "The combining power of an element" and Since, chlorine needs 1 electron to complete its valence shell, Its valency is 1.
<u>Answer:</u> The speed of the electron is
<u>Explanation:</u>
To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:
where,
= De-Broglie's wavelength =
h = Planck's constant =
m = mass of the electron =
v = speed of the electron = ?
Putting values in above equation, we get:
Hence, the speed of the electron is
Answer:
Explanation:
Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth
Answer:
The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M. In a neutral solution, then, pH = pOH = 7.
