Methane (CH4) gas is burned with 100% excess air in a closed rigid vessel at 298K, 1atm. Complete combustion forms products at 700K. The amount of heat transfer is measured to be 10,000 kJ. Assuming ideal gas mixtures for the reactants and products, find (a) the final pressure, (b) the amount of fuel, in kg.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
