What does barium and selenium make?
Barium (Ba) and selenium (Se) can react to form barium selenide (BaSe), a compound that consists of barium cations and selenide anions. Barium selenide is typically a solid at room temperature and can be used in various applications, including electronics and as a semiconductor material. The reaction between barium and selenium involves the transfer of electrons, typical of metal and non-metal interactions.
What does selenium and oxygen combined together make?
Selenium dioxide, SeO2
How many protons and neutrons does selenium have?
This isotope is shown in hyphen notation: on the left side of the hyphen is the isotope's name, and on the right side is the isotope's mass number. The mass number of an element is the total number of particles in the nucleus (the number of protons + neutrons an atom has).In order to get the number of protons an atom has, find its atomic number on the periodic table. Selenium's atomic number is 34.... wait, this doesn't make any sense. If it has a mass number of 30 and an atomic number of 34, it has -4 neutrons.I'm sorry, but it looks like you have the problem wrong.
Does calcium and barium have the same or different reactivites?
Calcium and barium have similar reactivities, as both are alkaline earth metals located in Group 2 of the periodic table. However, barium is generally more reactive than calcium due to its larger atomic size and lower ionization energy, which make it easier for barium to lose its outer electrons. Both metals react with water and acids, but barium's reactions tend to be more vigorous.
Why does barium make flames green?
It is the characteristic colour of a barium flame.

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 elements make up the compound barium hydroxide?
Barium hydroxide is composed of one barium ion (Ba2+) and two hydroxide ions (OH-), resulting in the chemical formula Ba(OH)2.
Does barium plus barium make a reaction?
No.
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.

How many grams of barium chloride are needed to make 100. grams of barium sulfate?
89.3
How can you identify Sulphate anions in a unknown solution?
Dip a copper coin in that unknown solution And make that solution slightly acidic. After about one hour, take out the copper coin and if there are green colours deposits then there is sulphate, otherwise not.
