The pure form of sodium hydroxide is solid. Compared to the pure form, the aqueous form of the liquid is actually many times more volatile. For this very reason, it is advised that the bottles used to keep samples of NaOH be kept closed.
neutrons have a neutral charge
Answer:
The volume of the gas at a pressure of 65.0 kPa would be 363 mL
Explanation:
Boyle's Law is a gas law that relates the pressure and volume of a certain amount of gas, without temperature variation, that is, at constant temperature.
Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. In other words, the product P · V remains constant at the same temperature:
P*V=k
Being P1 and V1 the pressure and volume in state 1 and P2 and V2 the pressure and volume in state 2 are fulfilled:
P1*V1=P2*V2
In this case:
- P1= 45 kPa= 45,000 Pa (being 1 kPa=1,000 Pa)
- V1= 525 mL= 0.525 L (being 1 L=1,000 mL)
- P2= 65 kPa= 65,000 Pa
- V2= ?
Replacing:
45,000 Pa* 0.525 L= 65,000 Pa*V2
Solving:
V2=0.363 L=363 mL
<u><em>The volume of the gas at a pressure of 65.0 kPa would be 363 mL</em></u>
This is because air is trapped inside the car and it heats up to the same temperature of the car. Think of the car as a greenhouse.
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.
