How many molecules are there in 7.27 miles of ammonia?
NemiM [27]

Hey There!

To solve this question remember that 1 mole of ammonia is equal to 17G of ammonia.

Using that, we first multiply 17 by 7 = 24

Then we multiply 7 by .27 = 1.89

Finally, taking those and adding them together gives you the answer...

<u>25.89 grams :)</u>

<u>Have a great day, I hope I helped.</u>

In the reaction between the strong acid HCI and the strong base NaOH which of the ions listed below is a spectator ion?
qwelly [4]

Answer:

Na+

Explanation:

The equation would be:

HCl (aq) + NaOH (aq) --> HOH (l) + NaCl (aq)

The equation is already balanced and the NaCl will disassociate in Na+ and Cl- and HCl will disassociate into H+ and Cl- and NaOH will disassociate into Na+ and OH-. Na+ is on both sides of the equation and stays the same, so Na+ will be the spectator ion.
