Is there a limit to the time contrast medium can stay in the warmer?

usually on the manufacturer information sheet should have storage requirements. I know for a fact Visipaque 320 can be in a warmer for 30 days once warmed to 98'. if it goes over it must be disposed of. when stored in regular temp 68-77 until expiration date.

the uses of barium
  • glassmaking
  • barite is extensively used as a weighting agent in oil well drilling fluids, and in making rubber
  • the carbonate is a rat poison
  • the nitrate and chlorate give green colours (CARE!) in pyrotechnics
  • sulphide is a white pigment
  • making rubber
  • rat poison
  • used in television screens as an oxide with strontium
  • medical applications

What is the chemical formula and CAS number for oxygen gas?

THE CHEMICAL FORMULA FOR OXYGEN IS O2 MEANING THAT THERE ARE TWO ATOMS IN OXYGEN MOLECULE.FRUTHER MORE IT IS IMPORTANT TO NOTE THAT SINGLE ATOM OF OXYGEN CANNOT BE SUSTAINED IN THE SYSTEM WITH NORMAL TEM AND PRESSURE.THE EVER EXISTING ATOM OF OXYGEN IS CALLED AS NASENT OXYGEN A CAS registry number is separated by hyphens into three parts, the first consisting of up to 6 digits, the second consisting of two digits, and the third consisting of a single digit serving as a http://www.answers.com/topic/check-digit. The numbers are assigned in increasing order and do not have any inherent meaning. The checksum is calculated by taking the last digit times 1, the next digit times 2, the next digit times 3 etc., adding all these up and computing the sum http://www.answers.com/topic/modular-arithmetic 10. For example, the CAS number of http://www.answers.com/topic/water-annabelle-chvostek-album is 7732-18-5: the checksum is calculated as (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) = 105; 105 mod 10 = 5.

Is barium a native mineral?

Barium is not a mineral, but is a chemical element. Barium, an alkaline metal, is quite reactive, and it is never found free in nature. Rather, it forms compounds that make up some minerals like barite, which is barium sulfate, and witherite, which is barium carbonate.

Why is barium compound toxic?

Barium is not poisonous in the form of its sulfate. That's because barium sulfate is insoluble in water. Unless a barium compound dissolves with the subsequent release of barium ions, it is not going to be highly toxic.

Can you eat while drinking Barium Sulfate?

You shouldn't be taking a Barium sulfate suspension unless you're about to have a medical scan.

It you're taking this regularly, you need to speak to your doctor.

If you are only taking it once (like is normally done before a scan), and you are concerned, you can save up breast milk to use the day after, and then should be able to breast feed again after it has cleared your system without concern. In either case, you should talk to your doctor.

What type of bond is barium nitrate?

A chemical compound such as barium nitrate never "is" any type of chemical bond; instead, the compound "has" or "contains" pairs of atoms joined by such bonds. Barium nitrate happens to contain both of the most common types of bonds: Barium cations are bound ionically to polyatomic nitrate anions, and the nitrate anions are internally bonded by three covalent bonds between the sole nitrogen atom and each of the three oxygen atoms.

How is barium used?

Barium is often used in barium-nickel alloys for spark-plug electrodes in vacuum tubes as drying and oxygen-removing agent. It is also used in fluorescent lamps: impure barium sulphide phosphoresces after exposure to the light. Barium compounds are used by the oil and gas industries to make drilling mud. Drilling mud simplifies drilling through rocks by lubricating the drill. Barium compounds are also used to make paint, bricks, tiles, glass, and rubber. Barium nitrate and chlorate give fireworks a green colour.

Barium and chlorine?

Barium (Ba) is an alkaline earth metal known for its reactivity, particularly with water, and is often used in medical imaging and fireworks. Chlorine (Cl) is a halogen gas that is highly reactive and commonly used as a disinfectant and in the production of various chemicals. When barium and chlorine react, they form barium chloride (BaCl₂), an ionic compound that is soluble in water and used in various industrial applications. The reaction reflects the tendency of barium to lose two electrons and chlorine to gain one, resulting in electrostatic attraction between the positively charged barium ions and negatively charged chloride ions.

What is the equation for barium with water?

The reaction of barium with water is: Ba(s) + 2H2O(l) → Ba(OH)2(aq) + H2(g)

What is in a barium enema that is different than the enema for a colonoscopy?

A barium enema, also known as a lower GI (gastrointestinal) exam, is a test that uses x-ray examination to view the large intestine. There are two types of this test: the single-contrast technique where barium sulfate is injected into the rectum in order to gain a profile view of the large intestine; and the double-contrast (or "air contrast") technique where air is inserted into the rectum.

Where is the lowest electronegativity barium calcium magnesium or strontium?

Both are ions and we should consider the ionic radius, not the atomic radius.

Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+).

Both ions have the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.

What is the symbol of barium and number of neutrons?

The symbol is Ba. The number of neutrons equal the number of protons.

What type of bond occurs between barium and sulfur?

An ionic bond would occur between sulfur and barium.

Is barium iodide a salt?

Yes, Im taking chemistry at the community college. Barium dichloride is an anhydrous salt.

Is barium metallic or nonmetallic?

Barium is a rare metal that is non magnetic

What is the reaction of calcium and barium?

Yes they are both alkaline earth metals in the same group on the periodic table

How does barium occur naturally?

Can be used in Fluoirescent tubes and also make Paint, Bricks, Tiles, Glass and Rubber.

What is barium x-ray?

scanning with barium is knownas barium cat scan
