Time left 1:29: H2CO (9) + CO2 (g) Using the following equations, 2CH3OH (g) + 302(g) 2CO2(g) + 4H2O (9) AH = -1253 kJ + O2(g) H2O () AH = -520 kj 2H2 (g) + O2(g) 2H20 (9) AH = -484 kJ determine AHrxn for the conversion of methanol (CH3OH) to formaldehyde (H2CO) and hydrogen gas (H) CH3OH) + H2CO3 (g) + H2 (9) O None of them 75.5 kJ 0 95.5 kJ O 135.5 kJ 085.5 kJ If gases X and SO2 are 100 cm away from each other and sent out at the same time. If the two gases meet 20 cm away from SO2, which of the following statements are false? [Molar mass of SO2 = 64 g] O The molar mass of X is 2.56 g/mole O If we increase the temperature of SO2 and keep the temperature of X constant, meeting point of gases get closer to X If we decrease the temperature of both gases by the same amount, meeting point does not change O X is faster than SO2 O The molar mass of X is 4 g/mole PDF Chantar Saxon dhe
