The change in energy is given by the change in gravitational potential energy:
The average rate of change in terms of time is approximately this:
The awnser is A. Idek I looked it up so yeah that’s the awnser
Kevlar would be the answer!! enjoy the rest of your day broskies!!!
The balanced chemical reaction is:
<span>N2 + 3H2 = 2NH3 </span>
We are given the amount of H2 being reacted. This will be our starting point.
26.3 g H2 (1 mol H2 / 2.02 g H2) 2 mol
O2/3 mol H2) ( 17.04 g NH3 / 1mol NH3) = 147.90 g O2
Percent yield = actual yield / theoretical
yield x 100
Percent yield = 79.0 g / 147.90 g x 100
Percent yield = 53.4%
