Given the equation representing a reaction: h2co3 + nh3 → nh4+ + hco3– according to one acid-base theory, the compound nh3 acts as a base because it

1. accepts a hydrogen ion
2.donates a hydrogen ion
3.accepts a hydroxide ion
4.donates a hydroxide ion

How can carbon move from "land" to bodies of water? describe the way human impact has lead to increased levels of co2 in the atmosphere.

Be sure to answer all parts. the following equilibrium constants were determined at 1123 k: c(s) + co2(g) ⇌ 2co(g) k'p = 1.30 × 1014 co(g) + cl2(g) ⇌ cocl2(g) k''p = 6.00 × 10−3 calculate the equilibrium constant at 1123 k for the reaction: c(s) + co2(g) + 2cl2(g) ⇌ 2cocl2(g) 4.68 × 10 9 (enter your answer in scientific notation.) write the equilibrium constant expression, kp:
