Answer:
1) Endothermic.
2) 
3) 
Explanation:
Hello there!
1) In this case, for these calorimetry problems, we can realize that since the temperature decreases the reaction is endothermic because it is absorbing heat from the solution, that is why the temperature goes from 22.00 °C to 16.0°C.
2) Now, for the total heat released by the reaction, we first need to assume that all of it is released by the solution since it is possible to assume that the calorimeter is perfectly isolated. In such a way, it is also valid to assume that the specific heat of the solution is 4.184 J/(g°C) as it is mostly water, therefore, the heat released by the reaction is:
3) Finally, since the enthalpy of reaction is calculated by dividing the heat released by the reaction over the moles of the solute, in this case NH4Cl, we proceed as follows:

Answer:
hydrocarbons are the answer
The result for TEST FOR LIFE is that the sample produces ATP. The sample is plant.
D Is going to be your answer
Explanation:
The chloroplasts are cell structures that are photosynthesis. The Golgi apparatus is the site transport of substance out of the cell. Mitochondria is the site of cellular respiration.
The two main functions of organelle is that it stores the herediatary material, DNA and it coordinates the cell's activities like growth, intermediary metabolism, protein synthesis, and reproduction. Eukaryotes are the cells of advanced organisms have a nucleus.
The results of the sample produces ATP, the sample is plant and the plant cells have an envelope surrounding the nucleus.
Hope this helps.!!! And please mark brainliest thank you!!
