Many copper salts are blue in solution, and I suspect that's what you're thinking of, but it's not by any means the only element that can be blue. Chromium, vanadium, and magnesium can, in certain oxidation states, be bluish, as can some nickel complexes.
its not D. none of the above
Ionic compounds produce electrolytes; covalent compounds not.
Sodium compounds, such as sodium nitrate or sodium chloride, are commonly used to produce a yellow color in fireworks. When these compounds are ignited, they emit a bright yellow flame.
As a Christian I feel that this question is very offensive.
Barium compounds, such as barium chloride, are often used in fireworks to produce a green color when burned. When barium salts are heated, they emit green light due to the energy absorbed and then released by barium ions.

No, carbon is not an alkali. It is a non-metal element that is commonly found in organic compounds and all living organisms. Alkalis are a subset of bases that dissolve in water to produce hydroxide ions.
Acids dissolve in water to produce H+ ions, while bases dissolve in water to produce OH- ions. This process is known as ionization or dissociation, and it is a key characteristic of acidic and basic solutions.
Acidic oxides are compounds that react with water to form acidic solutions. These oxides typically contain nonmetals, such as sulfur or nitrogen, and when they dissolve in water, they produce acidic solutions capable of neutralizing bases. Examples of acidic oxides include sulfur dioxide (SO2) and nitrogen dioxide (NO2).
Fluorine is not typically thought of as dissolving in the same way that solids dissolve in liquids. However, fluorine can react with certain substances to form compounds or mix with other elements to create fluorine-containing solutions.
Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds. This method of extraction is called bioleaching.
Oxides of non-metals like sulfur dioxide, carbon dioxide, and nitrogen dioxide can react with water to form acidic solutions. These oxides dissolve in water to produce acidic compounds like sulfuric acid, carbonic acid, and nitric acid, respectively.
True. Molecular compounds that dissolve in water do not conduct electricity because they do not dissociate into charged ions when dissolved. Since they do not produce free ions that can carry an electric current, they are unable to conduct electricity in aqueous solutions.
Nearly all metals will form ionic compounds with oxygen, or 'oxides', as they are called.
Ionic compounds produce electrolytes; covalent compounds not.
Nitrogen containing gases dissolved in vapor in the atmosphere can produce compounds such as nitrogen dioxide (NO2) and nitric acid (HNO3), which contribute to air pollution and acid rain. These compounds can have harmful effects on human health, vegetation, and ecosystems.
Sodium is a metallic element, it produces no other things by itself. However it is very reactive with many other elements or compounds.
