In the balmer-rydberg equation (given in the introduction), what value of m is used to determine the wavelengths of the balmer s
EastWind [94]

The value of m in the Balmer-Rydberg equation is equal to TWO (m= 2). It is part of the Balmer series.

<h3>What is the Balmer series?</h3>

The Balmer series is one of a group of series that describe the spectral line emissions of a hydrogen atom.

The Balmer-Rydberg equation refers to a mathematical equation between spectral lines.

The Balmer-Rydberg equation indicates the wavenumber of the spectrum for hydrogen regarding the Rydberg constant.

The Balmer-Rydberg equation considers the wavelength of the photon,  the atomic number and integers indicating spectral lines.

If we observe the price of a good or service rising then the most likely cause is increase in demand or a temporary surplus?
erik [133]
Usually (rises) because of general economic growth. if there is a high demand for the goods then the price will most likely rise in order for consumers to buy a limited amount. its also a sort of scheme to increase the full potential of price. prices for a good would probably not rise if the producer/provider has an exceptional amount of stock. from price changes you can determine the demand. high price is high demand and less stock. low price is low demand and likely a surplus therefore the low price is to remove the surplus more easily (low demand)

Krypton is named after the Greek word that means “secret.” Which explains why krypton was most likely given this name?
bekas [8.4K]

Answer:

Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.

Explanation:

Krypton (₃₆Kr), an element with atomic number 36, belongs to group 18 on the periodic table of elements. This group is a specific one - it's made up of elements known as noble gases. Besides krypton, these elements are: helium, neon, argon, xenon, and radon. All noble gases were characterized relatively late compared to other elements. They all conduct electricity, fluoresce, and are odorless and colorless. Besides that, they have very low chemical reactivity. Because of their stability, they are often used to maintain a safe, constant environment. As krypton shares all of these characteristics, it was difficult for chemists to find it. That's why it was most likely given that name.
