Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give ...
We could, for example, use solar cells to do the electrolysis of water "for free," but we could just as easily store the same energy in batteries and use those to power our cars instead. Fuel-cell cars sound promising, but if battery cars really are better, hydrogen may turn out to ...
Define and explain the process of electrolysis in electrolytic cells. Explain chemically how an electrolytic cell works for both the hydrolysis of water and electroplating. What happens to the current flow with time in an electrolytic cell? Explain. Define (a) a coulomb, (b) an electric cur...
Explain the following statement on the basis of osmosis or osmotic pressure: when sprinkled with sugar, a dish of sliced fruit will form its own juice. What are the effects of acids and bases on the browning of apples? Explain the zeolite...
Define and explain the process of electrolysis in electrolytic cells. Explain how a chemical reaction occurs according to the collision model. Explain the meaning of the orientation factor in this model. Explain in detail how urea works in our body and the urea cycle. Describe the Raschig process...
Answer to: Individuals living near copper mines sometimes earn extra money by suspending iron objects in the mine wastewater. Explain why the iron...
However, that really applies only to things likeelectrolysis(passing electricity through a chemical to split it up). Batteries are like electrolysis going backwards (they split up chemicals to make electricity) so the terms anode and cathode are switched around. Okay? To avoid confusion, I suggest...
Is the dissolution of borax in water exothermic or endothermic? Is the process of liquid water being converted to ice endothermic or exothermic? Determine the heat of reaction of the following chemical reaction using standard heats of formation. Then classify the reaction as endothermic or exothermic...
