The answer is A,because the way your question is written,there would be 4 molecules of salt (NA) and one molecule of CL (Chlorine)

so, that gives you the compounded amount, after 10 years, if you want to know how much interest was earned? well, just subtract the Principal from the Amount, or A - P <--- that's how much interest was earned
Answer:
No.
Step-by-step explanation:
3/4 is not less than 2/10.
3/4 = 15/20
2/10 = 4/20
15/20 > 4/20
The answer is 75% because 150/200 converted to a percent is 75%
150/200= 0.75
0.75 x 100 = 75%
