2N2 + 3O2 ---> 2NO + 2NO2
You should do it based on moles and not grams.
1.14 g O = 0.071 moles O
1 g N = 0.071 moles N
So in NO2 you need 2 moles O for each mole of N
1 g N = 0.071 moles, so you need 0.071 x 2 moles of O = 0.0.142 moles O
0.142 moles O x 16 g/mol = 2.27 grams of O. So, you are actually correct because your answer is 2.28 grams. I just prefer to work it out in moles so it makes perfect chemical sense.
The answer is A) Water has surface tension.
This is the correct answer because water allows animals and really light items to rest upon the top of the water.
Hope This Helps! If you could mark me as the brainiest answer, that would be amazing. I want others to read this answer and know it is accurate. If you need help with another question, just ask. :)
