Answer:
84.0 ppm is the concentration of Red 40 dy in the original sports drink.
Explanation:
Concentration of red dye in sport drink before dilution 
Volume of the sport drink before dilution 
Concentration of red dye in sport drink after dilution 
Volume of the sport drink after dilution 
( dilution )
84.0 ppm is the concentration of Red 40 dy in the original sports drink.
Answer: It is a gas
Explanation:
The most unique thing about nitric oxide being a neurotransmitter is that it is the only neurotransmitter which is in gaseous form.
Nitric oxide is small gaseous molecules which is synthesized by the de novo process in the neuronal tissue.
It can diffuse by plasma membrane.
It diffuses out of the postsynaptic neurons and acts on the neighboring neurons and presynaptic terminals to assist the generation of the Long Term potentiation.
Answer:
Explanation:
Entropy is the measure of randomness of a system . When heat is added to a gas , gas molecules become more random and therefore , their entropy increases . Hence at higher temperature , entropy increases and randomness increases due to addition of heat .
Hence when a gas molecules become more ordered that means entropy decreases . Hence heat is withdrawn from the system . Hence temperature of the system is decreases .
In the given case , gas molecules are made more ordered that means their temperature is decreased to lower the entropy before they are exhausted .
