Why does barium give a green flame test?
The heat of the flame excites the metals ions, causing them to emit visible light. The characteristic emission spectra can be used to differentiate between some elements.SO the characteristic emission spectra of Barium contains wavelengths corresponding to green color.
In a flame test what color flame will barium chloride have?
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy. This energy corresponds to a wavelength of light, which is emitted from the ion. This wavelength corresponds to green light, hence the green flame observed.
Calculate the molarity of a solution that contains 35.0g of barium chloride dissolved in 450.0ml solution?
First, calculate the number of moles of barium chloride using its molar mass. Then, convert the volume from milliliters to liters. Finally, divide the number of moles by the volume in liters to find the molarity of the solution.
What mass of barium sulfate can be produced when 100.00 ml of a 100 M solution of barium chloride is mixed with 100.0 ml of a 100 M solution of iron III sulfate?
To find the mass of barium sulfate produced, first calculate the moles of barium chloride and iron III sulfate using their volumes and concentrations. Then, determine the limiting reactant by comparing the moles of barium chloride and iron III sulfate and use it to find the moles of barium sulfate produced. Finally, multiply the moles of barium sulfate by its molar mass to find the mass in grams.
What is the name of BaO in chemistry?
Barium oxide is formed from barium and oxygen.
What is the Wavelength barium?
Barium has an atomic spectra of lines, not only one line (with one wavelength); I reccomend to consult a catalog of spectral lines. See the link below.
What is the emission spectrum of barium nitrate?
The emission spectrum of barium nitrate typically includes several bands of light in the visible region, with some lines in the blue-green part of the spectrum being the most prominent. The specific wavelengths and intensities of these lines can vary depending on the experimental conditions.

The number of atoms of barium in 68.2 g of barium phosphate?
To find the number of atoms of barium in 68.2 g of barium phosphate, you first need to calculate the moles of barium in 68.2 g of barium phosphate using the molar mass of barium phosphate. Then, you can use Avogadro's number to convert moles of barium to atoms of barium.
Why does barium burn green?
When barium burns, it releases energy in the form of light. The green color comes from the specific wavelength of light that is emitted as electrons transition energy levels within the barium atoms. This green light is typically associated with the presence of barium compounds in fireworks and pyrotechnic displays.
What wavelengths within the visible spectrum would most likely contain emission lines for barium?
Barium typically emits green and yellow light, so its emission lines in the visible spectrum are likely to fall within the green and yellow regions. This corresponds to wavelengths around 570-580 nm for green light and 590-610 nm for yellow light.
What is the mass in grams of barium in a sample of barium phosphate that also contains 10.0g of oxygen?
To determine the mass of barium in barium phosphate, we need to know the molar ratio of barium to oxygen in the compound. If we assume a 1:3 ratio between barium and oxygen in barium phosphate (Ba3(PO4)2), we can calculate the molar mass of barium and oxygen in the compound. With this information, we can find the mass of barium in the sample by subtracting the mass of oxygen from the total mass.
What element is an alkaline earth metal and in a flame test forms a green flame?
The element is barium. When barium is heated in a flame test, it produces a distinct green flame color due to the emission of specific wavelengths of light. Barium is an alkaline earth metal found in Group 2 of the periodic table.
Why tungsten in cathode ray tube coated with thorium oxide or barium oxide?
Tungsten is used in the cathode ray tube (CRT) because it has a high melting point and good thermionic emission properties, which means it can easily release electrons. The thorium oxide or barium oxide coating on the tungsten helps to improve electron emission efficiency by reducing work function and enhancing electron current. This combination allows for better electron beam production in the CRT.
What salt gives flames green color?
Barium salts, such as barium chloride or barium nitrate, are commonly used to produce a green flame when burned. The green color is a result of the specific wavelength of light emitted by the barium ions during the combustion process.
Calculate the molarity of a solution that contains 35.0g of barium chloride dissolved in 450.0ml solution?
First, calculate the number of moles of barium chloride using its molar mass. Then, convert the volume from milliliters to liters. Finally, divide the number of moles by the volume in liters to find the molarity of the solution.
