Barium is a radiopaque contrast medium used for imaging the digestive system, while iodinated contrast media are used for imaging blood vessels and organs. Barium is not iodinated and is not excreted by the kidneys, making it suitable for GI imaging. Iodinated contrast media are excreted by the kidneys and are used for imaging various parts of the body, including the brain, kidneys, and blood vessels.
Two electrons are transferred to sulfur from barium to form barium sulfide.
When evaluating the reactants barium oxide (BaO) and magnesium (Mg), one needs to determine if magnesium is more active than barium. Magnesium is indeed more active than barium in terms of reactivity, as it is higher on the reactivity series. This means magnesium can displace barium from its compounds, allowing for potential reactions between the two substances. Therefore, the comparison focuses on magnesium's ability to react with other elements and compounds compared to barium's reactivity.
The chemical equation for the reaction between barium and selenium is: Ba + Se → BaSe. This reaction forms barium selenide.
An ionic bond would occur between sulfur and barium.
Barium oxide, as an ionic compound, involves electron transfer between barium and oxygen ions. Barium (Ba) tends to lose two electrons to become a Ba2+ cation, and oxygen (O) tends to gain two electrons to become an O2- anion, forming a stable ionic compound. This electron transfer leads to the creation of a strong ionic bond between the barium and oxygen ions in barium oxide.
An Iodinated Contrast Medium
An ionic bond forms between barium and oxygen.
The compound formed between nitrogen and barium is barium nitride (Ba3N2). The formula indicates that three barium atoms combine with two nitrogen atoms to form the compound.
Oil-based iodinated contrast media are used primarily in radiography for procedures where prolonged visualization of the gastrointestinal tract is needed, such as barium enema. These contrast agents are denser and are not water-soluble, allowing better coating and adherence to the mucosal surface for improved visualization. They are typically used in cases where water-based contrast media are inadequate.

The ionic compound expected to form between sulfur (S) and barium (Ba) is barium sulfide (BaS). Barium has a +2 charge, while sulfur has a -2 charge when they combine, resulting in a neutral compound.
The ionic compound formed between barium and sulfur is barium sulfide, which has the chemical formula BaS. Barium is a group 2 metal with a 2+ charge, and sulfur is a group 16 nonmetal with a 2- charge. Therefore, to balance the charges, one barium ion (Ba2+) combines with one sulfide ion (S2-) to form BaS.
The reaction between chlorine and barium is called a single displacement reaction, where the chlorine displaces the barium in barium chloride to form barium chloride and elemental chlorine. The balanced equation for this reaction is: Cl2 + Ba → BaCl2 + Cl2
The chemical equation for the reaction between barium and selenium is: Ba + Se → BaSe. This reaction forms barium selenide.
The formula formed between sulfate ion (SO₄²⁻) and barium ion (Ba²⁺) is BaSO₄, which is known as barium sulfate. Barium sulfate is an insoluble compound that is commonly used in medical imaging procedures like X-rays to enhance contrast in the gastrointestinal tract.
