What is the percent yield if 107.50 g NH3 reacts with excess O2 according to the balanced equation below and the actual yield is found to be 154.70 grams of NO?
4 NH3 + 5 02 + 4 NO + 6H2O

I uploaded the answer to a file hosting. Here's link:

do origin keystone objects ok lap u v nap ya so I haha

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
