Dude solve my questions tooQ32
Statement 1 - Obviously disagrees with the sentence 'Carbon monoxide burns readily in oxygen to form Carbon dioxide'
Statement 2 - More negative means exothermic reaction (which is easy to occur), so it fits with the sentence
Statement 3 - Kc = [product] / [reactant], if this is high means there is high concentration of CO2 produced. Hence it fits.
Q9
Answer is A. In the equation they've given : SO3 --> SO4. The oxidation number of Sulphur increased from +4 to +6 (change is +2). So, for the metal, there should have been the same magnitude of change but in the negative direction. (Change = -2) So, because it is +3, it would become +1.
