They are kind of opposite processes. Chemical synthesis is execution of chemical reactions to make products. Like you take two substances, you put them together, they react and you have new a substance. For example.
here Sodium and Chlorine react to make a new substance which is Sodium Chloride.
Chemical decomposition is process of seperating a substance to different substances. There is a substance by a reaction this substance becomes two substances, Like : XY -> X+Y For example :
A. height of the liquid above the point
As Nicole walks to her dorm room after a study group in the library she sees a backpack being stolen. The neurotransmitter activated during this emergency situation is a. norepinephrine.
High levels of norepinephrine can also lead to headaches, high blood sugar, and sleep disturbances. Too much norepinephrine also causes anxiety, high blood pressure and heart rate, and organ stress. Drug withdrawal, chronic renal disease, and mental illnesses like PTSD can also result in high norepinephrine levels. Neurons discharge neurotransmitter, which are chemical messengers, into the synapse through synaptic vesicles. Some neurotransmitter work by increasing the neuron's negative electrical charge, which makes it less likely to activate. This is a deterrent effect. Serotonin is an example of this.

Coke to ice because coke has a higher temperature than ice.
Answer: 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by calorimeter =
Joules
C = heat capacity of calorimeter = ?
Initial temperature of the calorimeter = 
= 22.37°C
Final temperature of the calorimeter = 
= 24.68°C
Change in temperature ,
Putting in the values, we get:
The heat capacity of the calorimeter is
