Answer:

false?

Explanation:

The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds

What is the frequency, in hertz, of an electromagnetic wave with a wavelength of 625 nm?

Reika [66]

Answer:- Frequency is $4.80*10^1^4Hz$ .

Solution:- The wavelength of electromagnetic radiation is given as 625 nm and we are asked to calculate the frequency. Frequency is inversely proportional to the wavelength and the formula used to calculate frequency when wavelength is given is:

$\nu =\frac{c}{\lambda }$

where, $\nu$ is frequency, c is speed of light and $\lambda$ is the wavelength.

Value of speed of light is $\frac{3.0*10^8m}{s}$ . We need to convert the given wavelength from nm to m.

$1nm=10^-^9m$

So, $625nm(\frac{10^-^9m}{1nm})$

= $6.25*10^-^7m$

Let's plug in the values in the formula and calculate the frequency:

$\nu =\frac{3.0*10^8m.s^-^1}{6.25*10^-^7m}$

= $4.80*10^1^4s^-^1$ or Hz.

So, the frequency of the electromagnetic wave is $4.80*10^1^4Hz$ .

Salt formed by the partial neutralization of an acid by a base are

Makovka662 [10]

Answer:

D. Acidic salt

Explanation:

Acidic salts:

Salts formed by incomplete neutralisation of poly-basic acids are called acidic salts. Such salts still contain one or more replaceable hydrogen atoms. These salts when neutralised by bases form normal salts.
