OUTGASSING occurs with cast iron or cast metal substrates and can be prevented by preheating the part up to 250° F before applying the Teflon™ coating. Preheating the part will release all air that is trapped inside the substrate. BRITTLENESS usually means the part was over-baked. When the...
Robinson said road salt is the "cheapest material that we’ve managed to find" that can be widely used. But the problem is that it has a significant impact on the environment (in addition to the financial cost), mainly from the inevitable melt th...
Galvanized nails are iron nails that have been plated with zinc to prevent rusting. The relevant reaction is Zn^{2+}(aq) + 2e^- \to Zn(s). For a large batch of nails, a manufacturer needs to plate a total zinc mass of 1.60 kg on the surface to get adequat ...
Which would make a more efficient cooking utensil: an iron skillet or an aluminum skillet? Why?Thermal Properties of Metals:Metals tend to be good conductors of heat and electricity which happens because of the presence of unpaired electrons in the valence shell. ...

Describe what occurs in the redox reaction (rusting of iron) by identifying reactants and products. Another example of a simple redox reaction is the combination reaction of elements to form a compound. For each case below, how do the oxi...
Remember, boiling water will not change it chemically, but will only cause a phase change. Which change is a physical change? (a) Wood burning (b) Iron rusting (c) Dynamite exploding (d) Gasoline evaporating. What is the study of matter and its com...
