Answer:
The following statements apply to the general experimental procedure for determining the heat of reaction:
A. Measurements of the temperature of the solution in the calorimeter should be taken at regular intervals for several minutes before the reactant is added.
B. The solution in the calorimeter should not be stirred during the experiment because stirring will slow the reaction
D. Temperature readings need to be taken at regular intervals after the highest temperature reading is observed to determine the rate of heat loss from the calorimeter.

yes
Explanation:
Mountains can change in several ways over time. They can undergo erosion by rain and wind, as well as landslides due to flooding. Some mountains change via volcanic activity. They may also change due to earthquakes and shifting of tectonic plates
Answer:
2 KL + Pb(NO3)2 = 2 KNO3 + PbL2
Explanation:
KL + Pb(NO3)2 = KNO3 + PbL2 is unballanced equation, just balance from there :)
