Answer:
In the modern period table, the elements are arranged in the increasing order and depending on their physical and chemical properties they are classified into the different groups and atoms.
Alkali metals differ from alkaline earth metal in the atomic structure and their properties as all the alkali metals consist electron in the outer-most shell. And the earth alkaline metals has two outer electron in their shell. So, for achieving the configuration of noble gas the alkali metals loses one electron and the alkaline metal lose two electrons.
<h2>Answer:</h2>
The compound is known as the neurotransmitter or messenger chemicals.
<h3>Explanation:</h3>
- Neurotransmitters are the chemicals a type of messenger which is used to transmit information from one cell to the next cell.
- Some hormones are also known as messenger chemicals.
- The nerve cells are not linked to each other while they are separated from each other by a space known as synapses.
- The electric potential signal is converted into chemical signal by the release of neurotransmitters.
- These neurotransmitter signal next cell to produce equal amount of electric signal in nerve cell.
1 mole = 6.022 * 10^23 formula units.
1.84*10^24 formula units CaCl₂ * (1 mole CaCl₂/6.022*10^23 formula units CaCl₂) = 3.06 moles of CaCl₂.
There are 3.06 moles of CaCl₂.
