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...
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 ...
Is electrolysis endothermic or exothermic? Why is the formation of ionic compounds exothermic? Is burning a candle endothermic or exothermic? Is crystallization endothermic or exothermic? How is making ice cubes an exothermic reaction? Determine the energy change for the following reaction. Indicate if...
aELID磨削中,利用电解原理对砂轮进行在线阳极融解,在砂轮表面生成一层氧化膜 In the ELID grinding, carries on the online anode using the electrolysis principle to the grinding wheel to melt, in grinding wheel surface production oxide film[translate] ...
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 ...
Can electrolysis happen in liquids? Explain why or why not. What happens to raisins when you place them in saltwater? Very carefully explain which will evaporate faster under conditions: 50.0 mL of distilled water or 50.0 mL of seawater? How...
Why is Iron not recommended in the construction of steam pipes? Describe the metallurgy of copper. Why are some cooking pots lined with copper? When industrial chemists want to make chlorine and lye through el...
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...
As we've already considered, open-cycle OTEC can play a useful part in providing pure, usable water from ocean water. OTEC can also be used to produce fuels such as hydrogen; the electricity it generates can be used to power an electrolysis plant that would split seawater into hydrogen and...
Let's quickly clear up one point of confusion. At school, you may have learned that the cathode is thenegativeelectrode and the anode thepositiveelectrode? However, that really applies only to things likeelectrolysis(passing electricity through a chemical to split it up). Batteries are like elec...
