What is the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light? The

1 answer:

3 0

Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

O2- is the Lewis ______ in the following reaction

matrenka [14]

$O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$

<h3>What is lewis base? </h3>

Lewis base is a species that donates an electron pair.

In the above-given chemical equation, the $O^{2-}$ is the lewis base which is donating an electron pair to the central atom of $SO_3$ to form $SO_4^{-2}$ .

Hence, $O^{2-}$ is the Lewis base in the following reaction:

$SO_3(g) + O^{2-}(aq)$ → $SO_4^{2-}(aq)$

What is the density of a liquid if the volume is 25 mL and the mass is 20.0 g?

LenKa [72]

Answers:

Density = 0.8 g/mol.

Given data:

v = 25 ml

m = 20 g

δ = ?

Solution:

Formula for calculating density is given as,

Density = Mass / Volume

putting values

Density = 20.0 g / 25 ml

Density = 0.8 g/mol.
