b. silver and aluminum
c. copper and lead

question. Number four is a repeat of what we did in question number three, but now for three different electrochemical cells instead of just the one with calcium and iron. But the idea is to draw the structure or draw the electrochemical cell, and then identify what half reactions air occurring at each electrochemical cell. Identify what is oxidized and what is reduced and then right. The Net Ionic equation for the entire electrochemical cell. So for the first one, we have copper and tin. We go toothy activity, Siri&#x27;s and we find out 10 is higher on the activity Siri&#x27;s so it will be oxidized. Electrons will leave the tin and go to the copper, which is lower on the activity. Siri&#x27;s. So if electrons were leaving the tin than tin is being oxidized, tin is going to tin two plus giving off the electrons and copper. Two plus is accepting the electrons to become copper solid, so we have copper, two plus and zinc. I&#x27;m sorry tin as theme, reactant and then copper solid and tin two plus as the products. The next one is silver and aluminum. Aluminum is higher up on the activity Siri&#x27;s, so it will be oxidized and electrons will leave the aluminum and go to the silver if electrons air. Leaving aluminum than aluminum is becoming three plus in order to give up. Three electrons and silver is taking on the electrons to become silver Solid. Aluminum is oxidized, silver is reduced. The entire reaction then is silver plus, with aluminum going to silver solid plus aluminum three plus. And then we need a balance it to make sure we have a three plus charge on both sides. So we&#x27;ll put a three here, so we have three plus, which will require us to put a three on our silver over here. The last one, then is copper combined with lead. Lead is higher on the activity. Siri&#x27;s so electrons will leave the lad and go towards the copper lead, then is going to be oxidized so that it can have electrons. Leave it and then copper two plus is going to be reduced as it takes on those electrons to become copper solid, and the entire reaction is copper two plus plus lead solid going to copper solid plus lead two plus

Ronald Prasad · Answer

in order to predict which element will replace another in a reaction, we have to use our activity. Siri&#x27;s So, for a tin and sodium, sodium, has a higher activity than 10 so sodium will replace tin for be. We have flooring and I a dean. Flooring has a higher activity, so floor een will replace. I don&#x27;t Percy lead and silver lead has a higher activity than silver, so lead replace silver. And for D, copper and nickel on nickel has a higher activity than coppers or nickel will replace copper.

Angela Caffey · Answer

All right. So an alloy is a mixture of metals. Um, is a type of solution. So we&#x27;re talking about brass brass is a mixture of copper and zinc. Stainless steel is a mixture of iron and chromium. Uh, plus, it typically has other metal impurities such as a carbon Mulligan, um, nickel, silicon or magnesium. Um, bronze is a mixture of copper and 10 ah, as well as other impurities such as aluminum, manganese, nickel or zinc and then sterling. Silver is mostly silver, um, and typically mixed with copper on if it&#x27;s not copper than its.

Catherine Lemar · Answer

copper can be used in a variety of compounds. One common compound is coop right, which is copper. One oxide and its formula is C U 20 Another, uh, example is Chalco site, which is copper one sulfide and that see you to S and Koval Light is copper to sulfide, which is just C. U. S.

Jorge Villanueva · Answer

today we&#x27;re going over question 32 tricks about from this of some Cooperman rooms Eso a coup, praying the chemical formula c you to so toward being who tro who like our cover to Silva friend only copper for you to Yes, Nothing for seen proper to sofa from cover one. So fineness being copper to so fight. See you.

Amy Jiang · Answer

So we&#x27;re asked both breath and Ron puking copper. Uh, describe the difference between these two hours. What we know that for wrong. It&#x27;s an alloy back pain cooperative and where contain conference. We know that bronze alloys are stronger and resisting. Where and corrosion better than Sarah carpal copper. And that the best so bon. Always stronger, Where on Logan Better and your coffin.
