Answer:

The given statement is false.

Explanation:

Hydrogen bromide when dissolves in water it gives hydronium ions and bromide ions.The hydronium ions is due to association of hydrogen ion with water molecule.This means that hydrogen bromide is an acid.

$HBr+H_2O\rightarrow H_3O^++Br^-$

Where as bases are those compounds which free hydroxide ion sin their aqueous solutions.

$BOH\rightarrow B^++OH^$

So, from this we concluded that HBr is not a base but an acid.

An amino acid is usually more soluble in aqueous solvent at pH extremes than it is at a pH near the isolelectric point of the am

gogolik [260]

Answer:

Option B. At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent.

C. At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules.

exactly 1mol of n2o4 is placed in an empty 1 l container. if at equilibrium n2o4 is dissociated 20%, what is the value of equili

egoroff_w [7]

Answer:

K = 0.2

Explanation:

Based on the chemical dissociation of N₂O₄:

N₂O₄ ⇄ 2NO₂

The equilibrium constant, K, of the reaction is:

K = [NO₂]² / [N₂O₄]

Now, if 20% of N₂O₄ is dissociated, 80% remains as N₂O₄ = 0.8mol/L = 0.8M

as 20% is dissociated, 0.2moles of N₂O₄ were dissociated and 0.2*2 = 0.4mol/L of NO₂ are produced.

Replacing in K:

K = [0.4M]² / [0.8M]

If the particles of matter that make up a substance are relatively far apart and can move freely, the substance is in what state

Novay_Z [31]

Answer:

Gaseous

Explanation:

Gasses can move freely and do not form the shape of their containers

Liquids are more free than solids, but they conform to the shape of their container

Solids are not free
