Magnet to remove the iron, filter paper (or some filter that could trap sand) to remove the sand, and heat up the salt and water, causing the water to evaporate to separate them.
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.

N(Na)=0.255 mol
M(Na)=22.990 g/mol
m(Na)=n(Na)M(Na)
m(Na)=0.255*22.990=5.862 g
Answer:
Yes is possible
Explanation:
MnSO4*7H2O(s) → MnSO4(s) + 7H2O(g)
This should be an endothermic reaction. The water molecules are interacting with the Mn2+ and SO42- ions within the crystal lattice of the compound. You must overcome those interactions, and so that would require the input of energy.
