Is NABR an ionic or molecular bond?
NaBr is an ionic compound. Bromine has enough electronegativity that the electromagnetic force between the Br and the Na atoms is great enough that an electron transfers from the Na atom to the Br atom. So Br becomes negatively charged and Na becomes positively charged. How would you describe the following bond Na Br?

What is bromism in dogs?
/Veterinary/ To evaluate clinical signs, risk factors, and outcomes associated with bromide toxicosis (bromism) in dogs with idiopathic epilepsy treated with potassium or sodium bromide ... 83 clinically ill epileptic dogs with (cases; n = 31) and without (controls; 52) bromism ... were matched by the veterinary hospitals from which they were referred and by month of admission. A presumptive diagnosis of bromism was made in case dogs when treatment for primary clinical signs was limited to induction of diuresis or reduction in the dose of bromide administered, and this diagnosis was supported by serum bromide concentrations ... Common clinical signs of bromism included alterations in consciousness, ataxia, and upper and lower motor neuron tetraparesis and paraparesis. /A/multivariate analysis identified bromide dose at admission to the hospital as the only factor significantly associated with bromism. In all dogs with bromism, treatment via dose reduction or facilitated renal excretion of bromide resulted in rapid clinical improvement, although breakthrough seizures happened during treatment in 8 of 31 (26%) dogs ...

Why is sodium bromide used in oil wells?
Because of its high solubility in water (943.2 g/L or 9.16 mol/L, at 25 °C) sodium bromide is used to prepare dense drilling fluids used in oil wells to compensate a possible overpressure arising in the fluid column and to counteract the associated trend to blow out. The presence of the sodium cation also causes the bentonite added to the drilling fluid to swell, while the high ionic strength induces the bentonite flocculation .

What happens when CaCO3 is dissolved in water?
When solid CaCO3 is dissolved in water, a population of chemical species is formed because CaCO3 does not dissociate entirely as Ca2+ cations and (CO3)2- anions. A very tiny fraction also exists as the neutral pair CaCO3. To make this clear, chemists generally add a superscript “0” after CaCO3 if they are referring to the neutral pair in an aqueous solution.
Why do covalent bonds stay gasses?
Now covalent molecules tend to stay as gasses because there is a very small intermolecular forces (i am not talking about large covalent compounds like diamond,graphite etc). Small intermolecular forces will require very less energy to overcome the attraction between molecules. They mostly are gasses but some are liquids and few are solids. (Donot con
What is an aqueous sample?
Chemically, an "aqueous" sample refers to a solution, typically with an element or an compound that has been dissolved in water. Most substance you see in the lab either has dissociated ions in water is considered such a solution, and is thus aqueous. (Note that covalent compounds do not dissolve in water, and thus is unable to make aqueous solutions with them.
What is covalent bonding?
Covalent bonding is sharing of electrons. If 2 non-metals are present in a compound like (O2,N2,NH3,SO2,etc) you immediately derive that the bonds are covalent. Now covalent molecules tend to stay as gasses because there is a very small intermolecular forces (i am not talking about large covalent compounds like diamond,graphite etc). Small intermolecular forces will require very less energy to overcome the attraction between molecules. They mostly are gasses but some are liquids and few are solids. (Donot confuse it with forces between atoms. Covalent bonds are very strong. i.e You cannot break N=N bonds, but you can easily overcome the forces of molecules like boil it etc. )
