List the following bonds to hydrogen in order of increasing polarity C-H O-H Al-H N-H?

Al-h , c-h, n-h, o-h


Is ammonium hydrogen carbonate a element or a compound?

Definetly a compound made up of N,H,O,C elements


Enter the follow bonds in order of increasing bond stretching frequency C-H F-H O-H N-H?

The bond stretching frequency increases with increasing bond strength. Therefore, the order of increasing bond stretching frequency is: F-H < O-H < N-H < C-H.


The analysis of an organic compound showed that it contains 0.175 mol C 0.140 mol H and 0.035 mol N. Its molecular mass is about 160 gmol. What is the subscript on C in the chemical formula?

The compound's empirical formula is CH3N, and its molecular formula is C4H12N. Therefore, the subscript on C in the chemical formula is 4.


A compound contains only carbon hydrogen nitrogen and oxygen combustion of 0.157g of the compound produced 0.213g CO2 and 0.0310g H2O In another experiment it is found that 0.103g of the compound?

Molar masses: C = 12 g/mol O = 16 g/mol H = 1 g/mol N = 14 g/mol CO2 = 44 g/mol H2O = 18 g/mol NH3 = 17 g/mol * 44 g CO2 is produced from 12 g C 0.213 g CO2 is produced from = (12)(0.213) / 44 = 0.0581 g C present in 0.157 g compound. * 18 g H2O is produced from 2 g H 0.0310 g H2O is produced from = (2)(0.0310) / 18 = 0.0034 g H present in 0.157 g compound. * 17 g NH3 is produced from 14 g N 0.0230 g NH3 is produced from = (14)(0.0230) / 17 = 0.0189 g N present in 0.103 g compound.(this is different) If in 0.103 g compound there is 0.0189 g N in 0.157 g compound there is ; (0.157)(0.0189) / 0.103 = 0.0288 g N * Mass of C, H and N = 0.0581 + 0.0034 + 0.0288 = 0.0903 g The rest is mass of O = 0.157 - 0.0903 = 0.0667 g Moles of elements in the compound sample: C = 0.0581 g / 12 g/mol = 0.00484 mol H = 0.0034 g / 1 g/mol = 0.0034 mol N = 0.0288 g / 14 g/mol = 0.00205 mol O = 0.0667 g / 16 g/mol = 0.00417 mol Smallest mole ratio: N = 0.00205 / 0.00205 = 1.00 C = 0.00484 / 0.00205 = 2.36 H = 0.0034 / 0.00205 = 1.66 O = 0.00417 / 0.00205 = 2.00 Multiplying by 3 we get; N = 3 C = 7 H = 5 O = 6 Simplest formula: C7H5O6N3
