2Na(s) + Cl2(g) - 2NaCl(s) + 822 kj

Is there any other part to this question? If not I'm pretty sure the answer is 205.5 kJ

Explanation:

822 kJ; 411 kJ/mol.

Explanation:

A chemist measures the enthalpy change during the following reaction: ()()()Use this information to complete the table below. Round each of your answers to the nearest kJ/mol. 1. ()()()Solution:  given reaction is 2Na + Cl2 --> 2NaCl         delta H = -822 KJ 1) 1/2Na + 1/4Cl2 --> 1/2NaCl divide the coficiant of given.

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
