A calorimeter that measures an exothermic heat of reaction by the quantity of ice that can be melted is called an ice calorimeter. Now consider that 0.100 L of methane gas, CH 2 (g), at 25.0°C and 744 mmHg, is burned at constant pressure in air. The heat liberated is captured and used to melt 9.53 g ice at 0°C ( Δ r a H of ice = 6.01 k J / m o I ). a. Write an equation for the complete combustion of CH 4 , and show that combustion is incomplete in this case. b. Assume that CO(g) is produced in the incomplete combustion of CH 4 and represent the combustion as best you can through a single equation with small whole numbers as coefficients. (H 2 O(I) is another product of the combustion.)

Solution Summary: The author explains that an equation for the complete combustion of methane should be written and that the combustion is incomplete. Standard enthalpy of combustion occurs when 1 mole of a substance is completely burnt in excess oxygen

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
