When comparing CN3- and CNC, which of the following is true? CN3- has a single bond, CN is shorter and CN3- is stronger. CN3- has a triple bond, CN3- is shorter and CN is weaker. O CN3- has a single bond, CN is longer and CN3- is stronger. CN3- has a double bond, CN3- is longer and CN is stronger. CN3- has a double bond, CN3- is shorter and CN is weaker.
When treated with excess hydrogen gas under catalytic condition, X mol of a certain hydrocarbon absorbed 11.2 L of hydrogen gas (measured at s.t.p). Which of the following is CORRECT? X = 0.25; the hydrocarbon is an alkene with two double bonds X = 1; the hydrocarbon is an alkyne with two triple bonds O X = 0.5; the hydrocarbon is an alkyne with one triple bond X = 0.5; the hydrocarbon is an alkene with two double bond X...
1. Double bonds are the only type of unsaturation observed in hydrocarbons. True False 2. Hydrogenation increases a hydrocarbon's degree of unsaturation. True False 3. Margarine has a lower degree of unsaturation than a liquid cooking oil, such as olive oil. True False 4. Oil, gasoline, and natural gas are all examples of: Hydrocarbons. Carbohydrates. Pure substances. Aromatic compounds. 5.Hydrocarbons are nonpolar, meaning they interact with one another via which intermolecular force? London Dispersion. Dipole-Dipole. Hydrogen bonding. Covalent bonding.
True or false? When the population variances are known, the test statistic that we use to compare two population means using two independent samples follows the standard normal distribution. True or false? A paired t-test with two columns of 8 observations in each column should use d.f =7
TRUE OR FALSE In conducting the 2-SampTTest, we use a pooled measure when the variances of the two populations are determined to be significantly different.
Python! True or false? When testing if two values are equal, we use the = operator. For example: if guess = 42: print("You guessed correctly!")
CH_3OCH_3 and CH_3OH can form a hydrogen bond with one another. Select True or False. True False
1. True or False. When we use the Rate of Return Method in evaluating more than one alternative, we cannot compare the IRR of mutually exclusive alternatives (or IRR of the differences between mutually exclusive alternatives) against those of other alternatives. Explain your answer.
41) True or False? Dative bonding occurs when both atoms in a bond contribute an electron 11 point] EXTRA CREDIT: 1) The MacArthur-Forrest process is a metallurgical technique for extracting gold from low-grade ore by converting the gold to water soluble aurocyanide metallic complex ions. It is the most commonly used process for gold extraction. Subsequent processing of aurocyanide allows recovery of pure gold. 4 Au + 8 NaCN + O2 + 2 H20 4 NaAu(CN)2 + 4 NaOH Using...
