Avoltaic cell uses the following reaction: 2ag+ (aq, 1 m) + fe (s) ↔ 2ag (s) + fe2+ (aq, 1 m) given that the standard reduction potential of ag+ to ag (s) is +0.80 v and the standard reduction potential of fe2+ to fe (s) is −0.44 v, calculate the standard cell potential, e°cell.−1.24 v1.24 v2.04 v0.36 v

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
