<h3>
Answer:</h3>
B Aqueous
<h3>
Explanation:</h3>
We are given the equation;
KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s)
- The equation shows a precipitation reaction or a double displacement reaction.
- Precipitation reaction because two soluble salts reacts to produce a precipitate as one of the product.
- Double displacement reaction because the salts exchange cations and anions to form new compounds
- In the equation;
- KBr is in aqueous state since all salts of potassium (K) are soluble in water.
- KNO₃ and AgNO₃ are also in aqueous state as all nitrates are soluble in water.
- AgBr on the other hand is in solid state since its a precipitate that is insoluble in water.
Answer: The Note
Explanation: Neurotransmitters are endogenous chemical substances that transmits signals through a NEUROMUSCULAR JUNCTIONS.
The signals are transmit from one NERVE CELL TO THE TARGET POINT such as Muscle cell,gland cell etc. Neurotransmissiom require the presence of synapse(the structure or medium through which neurosignals which can be an electrical or chemical signals to pass through).
Jamal is 2 miles away from his home.
Option B.
<h3><u>Explanation:</u></h3>
The initial distance of Jamal from his home is 8 miles. He needs to return home from his trip.
The speed that Jamal kept was constant for 30minutes and he drove at a speed for 12 miles per hour.
Speed of Jamal = 12 mph.
Time of travel = 30minutes =0.5 hours.
So distance traveled by Jamal = 
miles. = 6miles.
Initial distance of Jamal = 8 miles.
So final distance = 
miles = 2miles.
So Jamal is 2 miles away from his home.
Silver nitrate is an ionic bond because it is made up of metal, sliver, and a non-metal, nitrogen and oxygen. It is also a polyatomic ion (you only find polyatomic ions in ionic bonds).
