Answer to relevant QuestionsCalculate the percent composition by mass of the following compounds that are important starting materials for synthetic polymers: a. C3H4O2 (acrylic acid, from which acrylic plastics are made) b. C4H6O2 (methyl acrylate, ...Fungal laccase, a blue protein found in wood- rotting fungi, is 0.390% Cu by mass. If a fungal laccase molecule contains four copper atoms, what is the molar mass of fungal laccase? There are two binary compounds of mercury and oxygen. Heating either of them results in the decomposition of the compound, with oxygen gas escaping into the atmosphere while leaving a residue of pure mercury. Heating 0.6498 ...The reaction of an element X with element Y is represented in the following diagram. Which of the equations best describes this reaction? a. 3X + 8Y ( X3Y8 b. 3X + 6Y ( X3Y6 c. X + 2Y ( XY2 d. 3X + 8Y ( 3XY2 + 2Y Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid- fuel rocket motors. The reaction is Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s) What masses of iron(III) ...
