16. Let R(A, B, C, D, E, F) be a relation schema, and let S = {A -> B, AB -> C, AC -> E, B -> CF, BC -> DE} be a set of functional dependencies. Use the Chase test to determine if the decomposition of R into the relation schemas R₁(A, B, E), R₂(A, D), R₃(B, D, E), and R₄(B, C, F) is lossless. [Symbols: ->, \cup , \cap , ⊆, ⊂, in , ∉, ∅, −]

Consider following three reactions: CO2(g) + 3H2(g) = CH3OH(g) + H2O(g) $K_c = 1.4 \times 10^2$ CO(g) + H2O(g) = CO2(g) + H2(g) $K_c = 1.0 \times 10^5$ CO(g) + 2H2(g) = CH3OH(g) $K_c = 1.4 \times 10^7$ what is the Kc for following reaction. Round your answer to one decimal point 2CO2(g) + 5H2(g) = 1/2 CO(g) + 3/2CH3OH(g) + 2H2O(g)
