D) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case
No single geologic process did all those things. Gold is an element, a heavy element, so it accumulates in seams of hard rocks, quartz being most common. It accumulates over thousands of year
Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
Answer:
Number of atoms =1.806×10²⁴
Explanation:
You have the number of moles of Carbon tetrachloride which is n=3
And you are looking for number of atoms that are in the sample, which are represented by the letter "N"
The formula that has both number of moles(n) and number of atoms(N) is written as n=N/Na
Na is called the Avogadros number and it is equal to 6.08×10²³, it never changes(it is a constant)
So you will substitute the number of moles and the avogadros number to you formula, and the only unknown will be the number of atoms which you are looking for
- n=N/Na
- 3=N(6.02×10²³)
- N=1.806×10²⁴ atoms of CCl
NB: N does not represent the number of atoms only. It may also represent the number of particles or molecules...
