Why is iron more reactive than copper? Why is zinc used to coat Iron and not the other way around? Why is Iron not recommended in the construction of steam pipes? Why do zinc and lead nitrate to react? 1. What is galvanization? 2. What makes zinc preferred in the above...
Why is a wire used to connect the electrodes in an electrochemical cell? Why is iron more reactive than copper? Explain why electrolytic reduction rather than chemical reduction is often used to obtain active metals from their compounds.
Itssolid form is very explosive when shocked or heated to 275 degrees Celsius. In addition, it is very reactive with acids, chlorides, certain metals and their salts: Lead, Copper, Zinc, Cadmium, and Nickel. ... However, the hydrazoic acid generated when the sodium azide is dissolved is ...
Galvanisation is a process wherein a thin layer of zinc metal gets deposited on iron objects. This is doneto prevent rusting of iron by protecting it to come in contact with air and moisture. Zinc metal, being more reactive, reacts with air to form hard layer of zinc oxide, which preve...
Containing pennies, there is danger of the dog(s) opening the cans and ingesting the pennies, leading to zinc poisoning from the zinc inside the copper jackets. Always keep the can up where your dog(s) can’t get to it. For more information on things that can harm your dog(s), ...
So I think for me it comes to the point, is it better to handle lead or better to have probably more fumes (due to heat?) from flux ? I use no-clean L0 so it is the minimal amount of rosin core flux (I dont know or used if anything with no rosin works well), and I also...
Materials commonly used in electroplating for critical applications include gold, silver, copper, nickel, chromium, and zinc. Each of these materials has properties that are desirable for specific applications: 1. **Gold** is used for its excellent corrosion resistance, good thermal and e...
When considering eggshell formation and integrity, zinc, copper and manganese are all important components for a strong shell. A zinc deficiency can lead to reduced shell weight and strength, as it is involved in supplying carbonate ions during shell formation. As shell membrane fibers are distribut...
Zinc is a trace mineral in the human body, meaning that we only require a small quantity to function normally. Yet, more than300 enzymesandhormonesdepend on zinc to carry out important chemical reactions in the body. Zinc helps in maintaining healthy immunity by suppor...
Why is O2 required for cellular respiration? Why is UV-Vis better for quantitation than IR? Explain your answer. Explain why we need myoglobin and hemoglobin. How much zinc must a human being obtain from food every day (in mg)? Why does orange juice have a pH of 3? Explain why it is...
