Iron Fluoride

A chemical compound is a substance composed of atoms from two or more (different) elements. These compounds are formed by the creation of chemical bonds between the atoms of the different elements.

Helium and Neon are both elements, and in particular, they belong to a group of chemical elements called noble gases. Being noble gases, they are very stable and do not react easily.

Iron fluoride is a chemical compound consisting of the metal, iron, and the nonmetal, fluorine. When a metal and a nonmetal react to form a compound, they form ionic bonds to hold together the atoms of the different elements comprising the compound.

What is the molality of an aqueous solution that contains 29.5 g of glucose (C6H12O6) dissolved in 950 g of water (H2O)?

Gnesinka [82]

Molality is one way of expressing concentration of a solute in a solution. It is expressed as the mole of solute per kilogram of the solvent. To calculate for the molality of the given solution, we need to convert the mass of solute into moles and divide it to the mass of the solvent.

Molality = 29.5 g glucose (1 mol / 180.16 g ) / .950 kg water
Molality = 0.1724 mol / kg

If hydrofluoric acid is a stronger acid than acetic acid, which statement is most likely true?

Alchen [17]

Answer: The statement conjugate base of hydrofluoric acid is weaker than that of acetic acid is most likely true.

Explanation:

A strong acid upon dissociation gives a weak conjugate base. This can also be said as stronger is the acid, weaker will be its conjugate base or vice-versa.

Hydrofluoric acid is a strong base as it dissociates completely when dissolved in water.

For example, $HF \rightleftharpoons H^{+} + F^{-}$
