What does selenium and oxygen combined together make?
Selenium dioxide, SeO2
How many protons and neutrons does selenium have?
The atomic number of selenium is 34. So there are 34 protons. In Se-80, there will be 46 neutrons (80 - 34 = 46) Note: There is no isotope Selenium-30 as originally asked in the question.
Why does barium make flames green?
It is the characteristic colour of a barium flame.
How many grams of barium chloride are needed to make 100. grams of barium sulfate?
89.3
How does barium occur naturally?
Can be used in Fluoirescent tubes and also make Paint, Bricks, Tiles, Glass and Rubber.
How many particles make up a barium?
its atomic number is 56 its atomic weight is 137 hope that helps
How can you test a solution for the barium ions?
Acidify the given solution with a few drops of concentrated HNO3 followed by the addition of 4 mol dm-3 sulphuric acid or ammonium sulphate. A white precipitate implies that there are Barium (II) ions present in the solution. The objective of the test give above is to recognize the Barium(II) ions as the white precipitate of barium sulphate which is not soluble in most of the solvents. Adding a sulphate solution at first might cause distractions as other cations such as strontium also make white precipitates with sulphate ions. Those other precipitates dissolve in dilute nitric acid.
What process is used to make red glassware?
Red glassware is made by a process called coloring by ions. The ions cadmium, selenium and sulphur together makes bright shades of red and orange depending on quantities used.
Does barium plus barium make a reaction?
No.

What salt does hydrofluoric acid with barium hydroxide make?
Barium fluoride

How long does barium sulfate last in your body?
Barium sulfate is used as a contrast agent in some medical imaging. It is insoluble in water, so it sort of drifts through the gastrointestinal tract. This irritates the tissues, but doesn't act as an outright poison as barium ions (which are poisonous) are not released into solution.
How do you make a standard 0.1 M Barium Chloride?
