Fill in the missing chemical formulae in the tables below. acid conjugate base base conjugate acid HSO NO₁₂ ☐ H₂SO ☐ он ☐ H₂O co ☐

C+½ 020l co CO (s) 2 (g) CO+ 2 02(a) (g) AH = - 111 kJ %3D CO, 2 (g) Is this reaction endothermic or exothermic? (g) AH = - 394 kJ %3D -11 K3+(-394 C6st O2 (9)-yCO26) AH=-505 KJ Exothermic 2. a) Explain how AT would be affected if a greater amount of surrounding solvent (water) is used, assuming the mass of salt remains constant? b) Explain how qien would be affected if a greater amount of surrounding solvent (water) is used? Explain. If the following enthalpies are known: AH = - 95KJ 2 C+D A+2B- C) AH = + 50kJ B+X

kJ H2(g) + 0.502(g) → H₂O(g) AH-241.8- AS-44.5 J-mol¯-K-¹ mol So, mol¹KI החומר ??? H₂O(®) 130.7 H2(g) 205.2 02(g)

Given the following data C,H,(9) + 30,(9) → 2 CO,(g) + 2H,0(1) 2C,H6 (g) + 702(g) → 4 CO2(g) + 6H2O(1) AH=-3119.8 kJ 2H,(g) + O2(9) → 2H,O(1) AH= -1411.0 kJ AH=-571.7 kJ calculate A H for the reaction C2H4 (9) + H2 (g) → C,H6 (g) AH = kJ

Did I do this correctly?

what are the coefficients missing on the following equation?_KN03+_H2CO3--->_K2CO3+_HNO3 O (2,1,1,2) O (0,0,0,2) (2,2,0,0) O (0,0,0,0) O (2,2,2,0)

Name these organic compounds: Η H H H | | | Η· C C C C C=H | | | | | H H H H H — H Η structure — — H H - C C 1 1 Η - Η - - Η - H | H — C - Η | H name

Is this answer correct? Pretty sure it is, but I just want to make sure :) Thanks!
