Why does hydrogen gas liberate at Cu electrode in Zn-Cu cell?
In a zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
What happens when copper turnings are boiled with concentrated nitric acid?
Copper(II) nitrate, Water and Nitrogen dioxide are formed. Cu + HNO3 ----> Cu(NO3)2 + H2O + NO2

What is the balanced symbol equation for the reaction of copper II carbonate and nitric acid?
Copper II carbonate plus nitric acid produces copper II nitrate plus water and carbon dioxide. CuCO3 + 2HNO3 ---> Cu(NO3)2 + H2O + CO2

How many cubic feet are in a water tank if it hold 24618?
Assuming 24618 means gallons of water: There are 7.481 gallons of water per cu ft. Divide 24618 by 7.481 to find how many cubic feet of the tank are taken up by the water: 24618 ÷ 7.481 = 3290.7365 cu ft, or approx 3291 cu ft.
How many gallons of water will be required if the volume is 132000 cu ft?
132,000 cu ft = 822,206 Imperial gallons approx.
