Explain how the equation 4Fe(OH)2(s)+O2(g)→2Fe2O3(s)+4H2O(l) in the article illustrates the oxidation of the iron in the rectants.

If you wanted to make something out of metal but didn't want it to rust, what are your options?

Explain how the equation 4Fe(OH)2(s) + O2(g)→2Fe2O3(s) + 4H2O(l) in the article illustrates the oxidation of the iron ions in the reactants

A Predict the major products of the following reaction. Be sure to use wedge and dash bonds to show the stereochemistry of the products when it's important, for example to distinguish between two different major products. + Cl₂ 2 X Click and drag to start drawing a structure.

C app.aktiv.com Predict reagents needed to complete this E2 elimination reaction. Br Problem 17 of 40 H3O+ A heat NaH B heat 0 D E (CH)COK heat CH₂ONa (CH)COH heat Done

Please correct answer and don't use hand rating

Draw the structure of the product of this reaction. H CH2CH3 Br H-... H H3C KOH E2 elimination product • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • If there are alternative structures, draw the most stable one. • If no reaction occurs, draw the organic starting material. O + 98 // n ?

4. a) Give a suitable rationale for the following cyclization, stating the type of process involved (e.g. 9-endo-dig), clearly showing the mechanistic details at each step. H CO₂Me 1) NaOMe 2) H3O® CO₂Me

2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.
