Answer:
a supply of electric charges which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges.
Explanation:
There's your answer have a good day
Carbon, Lead and Silicon all have the same amount of valence electrons as Germanium. This can be determined by looking at their position on the periodic table. Within each column (group) all the elements have the same amount of valence electrons. This explains why they will all have very similar chemical properties.
1. If horizontal layers of sedimentary rock have a vertical fault running through them, then they cab predict where the fault begame by <span>matching up rock layers over distances.
2. Yes, because they it is use to </span><span>determine an age on a specified chronology in archaeology and geology. They can use these data to prove their theories.</span>
Explanation:
Calcium chloride is an ionic compound as it is formed by transfer of an electron to each chlorine atom.
So, being an ionic compound calcium chloride is able to dissociate completely into water.
Hence, the dissociation reaction will be as follows.
Since, two electrons has been lost by single calcium atom. Therefore, calcium atom will have a charge of +2.
Thus, we can conclude that the charge on the calcium ion, in elementary units is +2.
Answer:
Because they are extremely stable molecules, CFCs do not react easily with other chemicals in the lower atmosphere. ... Free chlorine atoms then react with ozone molecules, taking one oxygen atom to form chlorine monoxide and leaving an ordinary oxygen molecule.
