Question

the speed of boat in still water is 60 km ph and speed of stream 40km/ph find ped of upstream and downstream​

Answer 1

Answer:

An Arrhenius acid increases the concentration of hydrogen (H+) ions in an aqueous solution, while an Arrhenius base increases the concentration of hydroxide (OH–) ions in an aqueous solution.

The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and refer to the concentration of the solvent ions.

The universal aqueous acid–base definition of the Arrhenius concept is described as the formation of a water molecule from a proton and hydroxide ion. Therefore, in Arrhenius acid–base reactions, the reaction between an acid and a base is a neutralization reaction.

Answer 2

Step-by-step explanation:

Speed downstream = 60 + 20 = 80 kmph Speed upstream = 60 - 20 = 40 kmph
