Lines in one spectral series can overlap lines in another is rydberg

In several chemical elements, the Rydberg formula is used to compute the wavelengths of spectral lines.

<h3>What causes lines in a line spectrum?</h3>

A spectral line is similar to a fingerprint in that it can be used to identify the atoms, elements, or molecules in a star, galaxy, or cloud of interstellar gas. When we use a prism to split incoming light from a heavenly source, we often observe a rainbow of colours crossed by definite lines. It's worth noting that spectral lines can appear in other parts of the electromagnetic spectrum, however we can't use a prism to assist us identify them.

Emission lines are distinct coloured lines that appear on a black backdrop and correspond to certain wavelengths of light emitted by an item.

Absorption lines are visible as black bars.

Calculate the number of grams of oxygen gas in a 24L container at STP

romanna [79]

There are 34 g of oxygen in the container.

We can use the<em> Ideal Gas Law</em> to solve this problem.

$pV = nRT$

But $n = \frac{m}{M}$ , so

$pV = \frac{m}{M}RT$ and

$m = \frac{pVM}{RT}\\$

STP is 0 °C and 1 bar, so

$m = \frac{\text{1 bar} \times \text{24 L} \times 32.00 \text{ g}\cdot\text{mol}^{-1}}{\text{0.083 14 } \text{bar}\cdot\text{L}\cdot\text{K}^{-1}\text{mol}^{-1}\times\text{273.15 K} } = \textbf{34 g}\\$

Atmospheric pressure at the summit of mount everest is about one third the pressure at sea level, which is 760 mm hg. if oxygen

vichka [17]

Atmospheric pressure at sea level is 760 mmHg.
We have been told that at the summit the pressure is only one third the pressure at sea level.
Then the pressure at the mountain top is $\frac{760}{3}$ mmHg
Air is made of a mixture of gases. the pressure that each gas exerts individually contributes to the total pressure of the system. The pressure that each gas exerts is the partial pressure of that gas which depends on the mole fraction of that gas or percentage composition of the individual gas.
Partial pressure of Oxygen - total pressure x percentage composition
Therefore pO₂ - $\frac{760 * 0.21}{3}$ = 53.2 mmHg
Answer is 53 mmHg

What charged particle is produced during ionic bonds

Setler79 [48]

Answer:

An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation or a positively charged ion. The atom gaining one or more electrons becomes an anion which is a negatively charged ion.
