Answer:
Chlorine --> 89%
Explanation:
Step 1) Add each element's amu up to get the total mass of the compound.
12.011+1.008+3(35.453) = 119.378.
Step 2) Divide the total mass of chlorine by the total mass of the compound.
3(35.453) = 106.359
106.359/119.378 = 0.8909430548.
Step 3) Now multiply by 100 to get the percentage.
0.8909430548*100 = 89.09430548%
Step 4) Estimate and submit your answer
89.09430548% estimates to 89%
= 9.1 × 10^6
(scientific notation)
= 9.1e6
(scientific e notation)
= 9.1 × 10^6

Answer: 9.55 moles
Explanation: Moles are the base unit of atoms, molecules, ions, or any other substance. It is exactly 6.022 × 10²³ entities of any substance. The mole is equal to the ratio of the given mass to the molar mass.
Hope this helps :) If possible give brainliest
Answer:
C. hydrogen bonding
Explanation:
Ammonia and hydrogen fluoride are both able to exhibit hydrogen bonding due to containing nitrogen (in ammonia) and fluoride (obviously in hydrogen fluoride). Remember the unique qualities of NOF. :)
A + B = Products
This is the correct mechanism.
