1. Consider the reactions in the table. (a) Write the equilibrium constant in terms of activities for the chemical reaction of fire extinguishers: 2NaHCO3 (s) Na₂CO3 (s) + CO₂ (g) + H₂O (g) A,H= 135.54 KJ (b) At 300 K the equilibrium constant is 3.95x10-6 for the reaction in (a), what is A,Gº? (c) State in words: what happens to the equilibrium when temperature is increased? Then, verify by finding K for the reaction in (a) at 420 K.

O MATTER Calculating volume by combining the volume of simple shapes A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 27.0 cm long by 21.0 cm wide by 10.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 7.5 cm will be just barely submerged in the water. Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.1 L. 2 cm flask water Explanation Check © 2021 McGraw-Hill Education. AlI Riahts Reserved.
