When an atom becomes an ion does its mass number change?

1 answer:

8 0

Its mass number does not change because the atom is losing or gaining electrons, so the change is almost not measurable because the electrons weigh so little.

In other words: its mass number does not change

What is the wavelength if the frequency is 29.2 hz?

ZanzabumX [31]

Answer : The wavelength is $1.027\times 10^7m$

Solution : Given,

frequency = 29.2 Hz

Formula used :

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

where,

$\nu$ = frequency

$\lambda$ = wavelength

c = speed of light = $3\times 10^8m/s$

Now put all the given values in this formula, we get the wavelength.

$\lambda=\frac{3\times 10^8m/s}{29.2Hz}=0.1027\times 10^8m=1.027\times 10^7m$ $(1Hz=1s^{-1})$

Therefore, the wavelength is $1.027\times 10^7m$

During dry weather, the water level in a small pond drops because of

Sophie [7]

Water levels tend to drop in dry weather because of evaporation. The hot temperatures will cause the water to achieve its gaseous state and go up into the atmosphere.

Calculate the molarity and normality of 5.7 g of Ca(OH)2 in 450 mL of solution.

Kisachek [45]

The molarity and normality of 5.7 g of Ca(OH)2 in 450ml 0f solution is calculated as follows

molarity = moles/volume in liters
moles =mass/molar mass
= 5.7g/74g/mol = 0.077moles
molarity = 0.077/450 x1000= 0.17M

Normality = equivalent point x molarity
equivalent point of Ca(OH)2 is 2 since it has two Hydrogen atom

normality is therefore = 0.17 x2 = 0.34 N
