For the following reactions, identify the substance that is the oxidizing agent and the substance that is the reducing agent.
1.) C2 H4 + H2 -> C2 H6
2.) Fe2 O3 + CO -> 2FeO+CO2
3.) 2KI +Cl2 -> 2KCl + I2
the catalyst reacts with the reactants. B. A catalyst initiates a chemical reaction. C. A catalyst lowers the activation energy of the reacting molecules
In N2O, nitrogen is the central atom and the oxygen atom is terminal. In OF2, however, oxygen is the central atom.Use formal charges to explain why.
If it is known that 41.6 grams of PURE ELEMENT THAT IS NOT DIATOMIC represents 1.30 moles of this element, what is the atomic mass of the element?
What is the pH of the solution created by combining 1.70 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)? with 8.00 mL of the 0.10 M HC2H3O2(aq)?
Determine the amount of heat energy lost by the same amount (40.0 g) sample of water (specific heat = 4.184 J/goC) and same temperature change.
You decide to use gel filtration. This works brilliantly and you determine that your protein is 80kDa at the same time. But wait! The gene that corresponds to HMD predicts a protein of only 38kDa. What are two potential causes of this discrepancy?
Describe two different ways by which electrons can move from the valence band to the conduction band.
