how are there concepts related to each other: chemical reactions, specifically oxidation-reduction reaction, limiting reactants, reactants in excess, theoretical yields, actual yields, percent yields and Conservation mass Law.

Can you please help me answer this

Iron ore is impure Fe2O3.  When solid Fe2O3 is heated with an excess of carbon, iron metal, and carbon monoxide are produced.  From a sample of ore weighing 878 kg, 515 kg of pure iron is obtained.  What is the % Fe2O3, by mass, in the ore sample?

For the following, (1) predict the products, (2) write the balanced equation with formulas, (3) determine if it is a synthesis, decomposition or combustion reaction. 1. Dihydrogen Monoxide produces (SECOND HINT, THINK DIATOMICS) Synthesis, Decomposition or Combustion? Balanced Chemical Equation. and (HINT: 2 gases) Beryllium and Chlorine yield Synthesis, Decomposition or Combustion? Balanced Chemical Equation. Butane (C,H,,) and Oxygen produce Synthesis, Decomposition or Combustion? Balanced Chemical Equation. and

Please don't provide handwritten solution .... Help me.

How do you write a combustion reaction? Why is the oxygen on the reactant side never balance to the number of oxygens on the product side in a combustion equation?

This assignment will require some research. Choose a chemical reaction that is used in industry, research, or nature. DO NOT USE  the photosynthesis process or the cellular respiration process.  Photosynthesis and cellular respiration are not single chemical reactions; they are each a series of chemical reactions.   For the reaction that you choose: 1)  Write the balanced chemical equation for the reaction (include the phases). 2)  What is/are the reactant(s)? 3)  What is/are the product(s)? 4)  Why is this reaction important in either industry, research, or nature?

Note:- • Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. • Answer completely. • You will get up vote for sure.
