M1 = 17.45 M
M2 = 0.83 M
V2 = 250 ml
M1. V1= M2. V2
V1 = (M2. V2)/M1 = (0.83× 250)/ 17.45= 11.89 ml
Answer: The correct answer is a) Acetylcholine.
Explanation:
The acetylcholine is a very important neurotransmitter involved in the mediation of synaptic activity between neurons. Among its most important functions we find: expression of mood states, vasodilation, gastrointestinal motility, bronchoconstriction, circular iris muscle contraction and sweat gland secretion.
Therefore the correct answer is a) Acetylcholine.
Answer: I believe it is B
Explanation:
because it states that a chemical compound always contains exactly the same proportion of elements by mass
Answer:
Explanation:
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.
