Before mendeleev published his periodic table, dobereiner grouped similar elements into triads, in which the unknown properties

of one member could be predicted by averaging known values of the properties of the others. to test this idea, predict the boiling point of hbr from the boiling points of hc1 (−84.9°c) and h (−35.4°c). °c

Hydrogen bromide is the diatomic molecule with the formula HBr. It is a neutral compound and a hydrogen halide.To compute for the melting point of Br2 from the melting points of HC1 (−84.9°c) and h (−35.4°c). You must add these two amounts and divide it by 2 to get the answer:-84.9 + -35.4 / 2 = -60.15 degrees Celsius is the answer.

Compounds in alcoholic beverages that enhance flavor and appearance but may contribute to hangover symptoms are called:_____.
olga_2 [115]

Compounds in alcoholic beverages that enhance flavor and appearance but may contribute to hangover symptoms are called congeners.

<h3>Alcoholic beverages:</h3>

Congeners are compounds that add to the flavor, smell, and appearance of most alcoholic beverages. These substances may make hangover symptoms worse. Because they contain fewer congeners than whiskey, brandy, and red wine, clear alcoholic beverages like gin and vodka have less of a hangover-inducing effect.

The impact of ethanol, or the alcohol in your drinks, is the primary contributor to a hangover. It is a poisonous substance that acts as a diuretic in the body, which causes you to urinate more frequently and increases the likelihood that you will become dehydrated. The incidence and intensity of hangovers are both increased by congeners, substances created during the digestion and maturation of alcohol.
