When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (m = 163 m/z) is formed. in the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm–1. the 13c nmr and dept spectra are provided below. draw the structure of the product as the resonance contributor lacking any formal charges.

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
