Zinc Definition and 65 Threads

the XRD pattern of Zinc oxide and zinc oxide in acrylic acid ! I did XRD analysis of zinc oxide, and its peaks are at 31.7, 34.4, 36.2, 47.5, 56.6, 62.9 and 67.9 (2-theta degree). further, I did XRD of zinc oxide dispersed in acrylic acid/IPA. but it's weird ! Why I could got some peaks at...

I'm having some trouble understanding what happens when Zinc and Hydrochloric acid are reacted with Copper Sulfate as a catalyst. I *think* the Copper ion gets electrons from the zinc and turns into straight copper which leaves zinc free to react with the chlorine to form zinc chloride. Does...

The Latent Heat of sublimation for zinc(atomic mass = 65.4 u) at 600k is 1,990,000 j/kg. Assume that the zinc vapor can be treated as a monatomic ideal gas and that the volume of one kilogram of solid is negligible compared to that of the vapor. What percentage of the latent heat serves to...

I'm trying to find out what type of reaction this is. a drop of water is added to a small pile of chemicals in a dish, after a few seconds, a blue flame and smoke is produced. NH4NO3 reacts to form (with chlorine as catalyst) N2O and water the experiment is called oxidation of zinc, so...

Using a study of zinc deficient mothers a double blind test was conducted using a placebo group and a test group. Using a .05 significance level to test a claim that zinc supplimentation does increase weight at birth. The weights are measured in grams. How can I test to see if the zinc...

Hello, In a lab experiment, we filled 2 wells of a culture plate, one of them had 1.0 M CuSO4 and a piece of zinc metal, and the other well had 1.0 M ZnSO4 and a piece of copper metal. My question is: Which well has the reduced form of zinc and the oxidized form of copper? I know that...

did zinc react with zinc sulphate solution

Why Zinc is so commonly use coat metals such as steel? I know that its a good corrosion resistant metal to use but what properties of zinc make it good to use under normal atmospheric conditions? Does it have to do with the oxide layer that it forms around it?

The question basically states write a brief overview of the correlation between the properties and uses for copper, iron, aluminium and zinc. Now I know this sounds like a simple research task, it's supposed to relate to periodic trends and their placing on the table. It's in this area that...

Does zinc react with both acetic acid (CH3COOH) and phosphoric acid (H3PO4)? I can't figure out the chemical equations for them and am wondering if no reactions occur. Thanks.

If a metal(Cu) is negatively charged, and is put to touch an another neutral metal(Zn), the extra charges are shared by both metal. But, doesn't zinc tend to lose e-?

The hydrogen liberated at the cathode would coat the electrode so polarises the cell. And manganse (IV) oxide is used as a depolariser. I got an equation in my notes: 2MnO2 + 3H2 --> 2MHO(OH) + 2H2O. But evidently the oxygen doesn't balance. I tried looking on the internet but still no...

I have a problem that I need to solve that is quite extensive it boils down to this. I have a steel vat that's been plated with zinc and its being used to store sulfuric acid. I have to find corrosion rates, heat transfer and thermal stresses, elastic and plastic deformation problems, hydrogen...

Hello, I've heard rumors (frankly, not rumors, evidenced by some scientific papers), that zinc(II) ion has coordinated five ligands, four at a plane, and the fifth from top, to form a tetragonal monopyramidal environment. I have some doubts about this, because zinc (II) ion has d10...

I'm having trouble with sample AP Equation writing questions such as; solid zinc hydroxide is treated with concentrated sodium hydroxide solution. The sheet my teacher provided does not cover this reaction and many others is there any material out there that tells what will happen in most reactions
