Answer: 1 mol of Zn is 65.38g
Explanation: To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn. Hence, 1.34 g of Zn contains 0.020 moles of Zinc.
Answer:
is the overall voltage produced
Explanation:
Potassium and Tin are connected in an electrochemical series.
In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.
Here,
The voltage drop at potassium 
The voltage drop at Tin 
The net voltage
NaCl - inorganic
Phenol - organic
C2H6 - organic
Ca3(PO4)2 - inorganic
CH2O - Organic
MgCO3 - Organic
Basically, if it has Carbon (other than a few) it is organic.
Answer:
lead sulfate.
Explanation:
Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery recharges
