Barium is a chemical element with the atomic number 56 and the symbol Ba. It has a high reactivity content and is never found freely in nature.
432 Questions
Where can you get Barium salt?
Barium salts can be purchased from chemical suppliers, laboratory supply stores, and online chemical retailers. It is important to note that barium salts are toxic and should be handled with care and disposed of properly.
The chemical formula for barium molybdate is BaMoO4. It consists of one barium (Ba) atom, one molybdenum (Mo) atom, and four oxygen (O) atoms.
What color is the color of barium chloride?
Barium chloride typically appears as a white crystalline solid.
Reaction of barium with water?
Barium reacts with water to form barium hydroxide and hydrogen gas. The reaction is highly exothermic and can result in the production of heat and ignition of the hydrogen gas. It is important to handle barium with caution due to its reactivity with water.
Barium is a soft, silvery metal that is easily cut with a knife. Its hardness is relatively low compared to other metals.
Is barium a good conductor of heat?
No, barium is not a particularly good thermal conductor. Among elements it is rated number just about in the middle, number 55 from the top.
Thermal conductors are rated by W/cmK. Without going into the explanation, a higher number represents a better conductor, and 0.0 means no conductivity at all. Barium is rated at 0.186 W/cmK. By comparison, copper, which is second best as a thermal conductor among elements, is rated at 4.01 W/cmK.
Barium is an element, and so it is made up of atoms of barium. These are made up of electrons and protons and neutrons which, in turn are made up of quarks.
Metalloid. It touches the metalloid "staircase" on the periodic table.
Yes, Boron is a metalloid, intermediate between metals and non-metals. It exists in many polymorphs (different crystal lattice structures), some more metallic than others. Metallic boron is extremely hard and has a very high melting point.
Ammonium Chloride sublimes when heated whereas Barium Sulfate does not. Another method would be to add de-ionized water to the mixture. The solids left over will be the Barium Sulfate whereas the the Ammonium Chloride will be mixed with the de-ionized water. Weigh everything first, including the water because the Ammonium Chloride will sublime when dry if you try to evaporate the de-ionized water from the mixture.
When barium nitrate and iron react, they undergo a single displacement reaction. The iron replaces the barium in the nitrate ion, forming iron(II) nitrate and barium as products. The chemical equation for this reaction is: Fe + Ba(NO3)2 -> Fe(NO3)2 + Ba.
According to Lange, Semi-metals are: boron, silicon, germanium, arsenic, antimony, tellurium, polonium and astatine. Although, polonium and astatine, according to some authors, are not semi-metals. Gallium is a metal (4. period, 13th (IIIa) group).
What is the specific gravity of barium?
what is the specific gravity,luster,transparency,streak,cleavage,and fracture of barium?
What elements are in the compound barium chloride?
The elements in Barium Chloride (BaCl2) are Barium (Ba) and Chlorine (Cl).
When barium comes into contact with water, it reacts to form barium hydroxide and hydrogen gas. This reaction is exothermic, meaning it releases heat. Due to the highly reactive nature of barium, it is important to handle it with caution and avoid creating sparks or ignition sources during the reaction with water.
What color does Barium chloride burn?
What color? Green. Sources? See below. http://www.colourlovers.com/blog/2008/02/25/the-magical-colors-of-fireworks/ http://chemistry.about.com/library/weekly/aa062701a.htm
Barium loses two electrons in a reaction, so it becomes positive or a cation.
What is the solubility of barium phosphate in water?
The compound barium nitrite is a strong electrolyte. Write the reaction when barium nitrite is put into water?
A strong electrolyte dissociates completely into ions in aqueous solution. When barium nitrite, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.
Ba(NO2)2(s) Ba2+(aq) + 2NO2-(aq)
We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
What is the formula for barium hydrogen sulfate?
The chemical formula for barium hydrogen sulfate is Ba(HSO4)2. This compound is formed by combining one barium ion (Ba2+) with two hydrogen sulfate ions (HSO4-).
