Q:Do vinegar and copper make a poison?
Vinegar is acetic acid. Acetic acid + copper will give a solution of copper acetate. Copper acetate is extremely poisonous to fish and aquatic species. Though it's less toxic to humans (it's unlikely that you would consume enough vinegar from a copper container to kill you) it's perfectly possible that it could make you ill. Acidic solutions tend to make metals mobile (i.e. put them into solution). If you have copper water pipes in your home, they're safe because water tends to be neutral or alkaline. Try not to store any consumables in a copper container, many foods are acidic too.
Q:Copper, CPVC or PEX plumbing?
Copper: Advantages - Most durable material for potable water. Impervious to rodents and other animals. Disadvantages - Most expensive material. Sweating joints can be difficult. Must be insulated from freezing temps to prevent rupture. CPVC: Advantages - Least expensive material. Glue fittings are easy to put together. Easy to repair. Disadvantages - Susceptible to rodent damage. Glue has a tendency to fail when subjected to large temperature differentials. Tentative links between glue and adverse health effects (unconfirmed). Must be insulated from freezing temps to prevent rupture. PEX: Advantages - Not as expensive as copper. Not susceptible to freeze ruptures (PEX expands without breaking to allow ice buildup). Easy to repair. Nontoxic. Disadvantages - Use of specialized tools required for pipe fittings. Susceptible to rodent damage.
Q:copper carbonate + oxygen (heat) >> ... + carbon dioxide?
copper carbonate + oxygen (heat) copper oxide + carbon dioxide Ans: Copper oxide Cu2O or CuO both are possible.
Q:Excuse me, brass, stainless steel, aluminum, how many were the thermal conductivity of carbon steel tubes urgently?!
A. copper tubeCopper tube thermal conductivity, lambda =379.14W/ (M. DEG C)It has a thick wallB. stainless steel pipeThe thermal conductivity of various stainless steels is basically in the range of 10~30W/ (M DEG C) below 600 DEG C, and the thermal conductivity increases with the increase of temperature at 100 degrees centigrade,
Q:Which is more suitable for household water pipes, plastic copper tube and copper lined PPR pipe?
Did not come into contact with plastic coated copper pipe, the two pipes at home are considered very good, is very suitable. The outer layer of the plastic for anti-corrosion, key copper thickness and quality inside, choose the brand, installed well generally with no problem for decades, the quality of copper are better than other materials.
Q:IF copper sulphate will be used as a electrolyte and zinc and copper are two electrodes ......exlain the whole?
this is the a voltaic cell, two dissimilar metals ( copper and zinc) are immersed in an electrolyte ( a dissolved sulfate). If the metals are connected by an external circuit, one metal is reduced (gains electrons) while the other metal is oxidized ( loses electrons). copper is reduced and zinc is oxidized. The difference in the oxidation potentials of the two metals provides the electric power of the cell. Zn/ZnSO4 // CuSO4/Cu 2e- + Cu2+ ------> Cu reduction reaction of Cu ions to form copper metal. The valence state of copper is reduced from 2+ to 0 Zn --------> Zn2+ + 2e- oxidation reaction of zinc metal to a zinc ion Standard Reduction Potentials: Cu2+/Cu Eo = +0.340 V Zn2+/Zn Eo = -0.76V Cu has the highest reduction potential In order for a battery to work dE > 0 dE= Er - Eo dE = ECu - EZn = 0.34V - (-0.76V) = 1.12V this is the EMF ( electromotive force) Thats the way the battery works... sorry for my english
Q:What are the masses of copper and silver metals in the strip?
Copper 0.95g Silver 3.23g Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag 63.55g + 339.82g ---> 187.57g + 215.8g divide all by 63.55 1 + 5.35 ---> 2.95 + 3.40 so, 1g Cu makes 3.40g Ag we started with 2g, let's say one gram was used. 1g left of Cu + 3.40g Ag = 4.4 grams in total we're looking for 4.18... 4.4 - 4.18 = 0.22 off knowing that 1g Cu makes 3.4 Ag, lets try to find how much copper and silver we will need to make the difference of .22g 1g Cu makes 3.40g Ag 4.40g total dividing by 2 0.5g Cu makes 1.70g Ag 2.20g total because the amount of silver is dependent on the amount of copper is used in this react we ill make the 0.5g of copper to 0.05g to make the 0.22 total we need. That is, 0.05g Cu makes 0.17g Ag 0.22g total At last: 1 - 0.05 = 0.95g Cu 3.4 - .17 = 3.23g Ag making 0.95 + 3.23 = 4.18 total I'm sorry if this is all a bit messy or even not the way you were shown.
Q:Element Copper. How does copper make the world better? and also where do you find copper?
pennies are made of copper
Q:Is the connecting pipe of the air conditioner copper tube or brass tube?
Brass, because the use of relatively long time, contact with refrigerant, chemical reaction, looked like copper.
Q:How much are copper scraps per pound?
Depending on the grade of copper you can expect different pricing. See some basic price ranges below: No.1 Heavy Scrap Copper 1.12 1.27 lbs USD No.2 Scrap Copper 0.98 1.13 lbs USD Soldered Copper Pipe Scrap 0.84 0.99 lbs USD Light Scrap Copper 0.84 0.99 lbs USD No.1 Bare Bright Copper Wire 1.15 1.30 lbs USD No.1 Copper Wire Scrap 1.09 1.24 lbs USD No.2 Copper Wire Scrap 0.98 1.13 lbs USD No.1 Insulated Copper Wire 0.45 0.70 lbs USD
