Barium

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.

The oxidation number of barium is +2.

the answer is 28

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).

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.

The noble gas electron configuration for barium is [Xe] 6s2.

Barium loses two electrons in a reaction, so it becomes positive or a cation.

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-).

No, barium is not considered a magnetic material. It does not exhibit any magnetic properties under normal conditions.

As Barium's atomic number is 56 and as it has 2 electrons in its outer shell (this is also due to the fact that it is in Group 2) its valency is 2. It loses 2 electrons to attain the electronic configuration of Xenon whose atomic number is 54, so it is electropositive and is a metal.Therefore its valency is 2+.

The chemical formula for Barium Hydride is BaH2.

Ba = Barium

H = Hydrogen

Its molecular mass is 139.34288 g/mol.

Barium has an atomic number of 56, meaning it has 56 electrons in its neutral state. These electrons are arranged in energy levels and orbitals around the nucleus following the rules of quantum mechanics. The electron configuration of barium is [Xe] 6s2, indicating that it has two electrons in the outermost 6s orbital.

The symbol of barium is Ba. It is a soft, silvery-white alkaline earth metal that is commonly used in fireworks due to its green flame color.

The skeleton equation for the reaction between barium and bromine would be: Ba + Br2 -> BaBr2.

Barium itself is not considered a carcinogen. However, exposure to certain forms of barium compounds, such as barium sulfate or barium chloride, may be associated with health risks, including potential carcinogenic effects, depending on the level and duration of exposure. It is important to follow safety guidelines when working with barium compounds to minimize any potential health risks.

Molecular weight for Barium is 137.33 amu.

When barium ions (Ba^2+) in a solution react with carbonate ions (CO3^2-) or bicarbonate ions (HCO3^-), insoluble barium carbonate (BaCO3) is formed as a precipitate. This reaction can be used to selectively remove barium from a solution through precipitation, reducing its concentration. The precipitate can be filtered out from the solution, leaving behind a lower concentration of barium ions.

The density of barium chloride in water depends on the concentration of the solution. A common concentration of barium chloride solution is 1M, which has a density of around 1.32 g/mL. Higher concentrations will have higher densities due to the increased mass of barium chloride dissolved in the water.

for the most part you really can't tell if it's coloring the flame at all, that is if you're burning it right on a Bunsen burner. if you're lucky it might spark or give the slightest bit of a white flame.
