Consider these reactions, where M represents a generic metal. 2M(s)+6HCl(aq)⟶2MCl3(aq)+3H2(g)Δ1=− 667.0 kJ

HCl(g)⟶HCl(aq) Δ2=−74.8 kJ

H2(g)+Cl2(g)⟶2HCl(g) Δ3=−1845.0 kJ

MCl3(s)⟶MCl3(aq) Δ4=−182.0 kJ

Use the given information to determine the enthalpy of the reaction

2M(s)+3Cl2(g)⟶2MCl3(s)

Δ= ___kJ

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
