PLEASE, i need so much help. Do this one thing for me please. It's enthalpy, 3 parts. It's so fast just please... The following reaction occurs under standard conditions:

CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)

a. Which bonds are broken and which are formed during the reaction? (1 point)

b. Determine the enthalpy of the reaction. (2 points)

c. Is the reaction endothermic or exothermic? Explain. (1 point)

Which best explains why an iceberg floats?

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant

When an experimenter draws a conclusion that he assumes will apply to all situations set up similarly to his test situation, even though he cannot possibly have examined all possible test scenarios, the experimenter is using deductive reasoning inductive reasoning abductive reasoning subjective reasoning
