Which of the following statements about hydrogen bonds is NOT correct? A. Hydrogen bonds account for the anomalously high boiling point of water. B. In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C. Individual hydrogen bonds are much weaker than covalent bonds. D. Individual hydrogen bonds in liquid water exist for many seconds and even minutes. E. The strength of hydrogen bond depends on the linearity of the three atoms involved in the bond.

P. * 00 F. 回2 matti Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 120. liters per second of dioxygen are consumed when the reaction is run at 299. °C and the dioxygen is supplied at 0.94 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits.

See the example in Introduction for set-up of calculations. Calculate the number of (a) moles of N, and (b) atoms of N in 12.7 g of nitrogen gas, N2. You do not need to include units in your answer, as they have already been included below, and use MM of N2 = 28.0134 g/mol. Type your answers in %3D as an exponential expression (e.g. 1.23E-2 instead of 0.0123), where appropirate, and round your answers to three significant figures. moles of N = moles atoms of N = atoms
10. CHALLENGE. You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react "gas X" with "gas Y" to make the products, you get the following data (all at standard pressure and temperature): 1 volume "gas X" + 2 volumes "gas Y" → 2 volumes compound I 2 volumes "gas X" + 1 volume "gas Y" → 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y and suggest identities.
