Ok so rewrite the equation for yourself :).
N2 + 3H2 -> 2NH3 (Always check if it is balanced).
Ok so we have 2kg of hydrogen conver this to grams and then to moles.
2kg -> 2000g
2000g divide by R.M.M of H2
R.M.M
2H - 2 * 1 -> 2
2000/2 - 1000 moles.
Look at the ratio of H2 to 2NH3.
We see that we get 2NH3 for every H2 therefore the ratio is 1:2.
This means that we HAVE 2000 moles of 2NH3.
At stp. we know that 1 moles = 22.4 Litres
We have 2000 moles that means that we produce 44800 litres of NH3 at stp.
2000 * 22.4 - 44800
Hope this helps :).
I would say that it is physical because there are no chemicals when the glass is breaking.
<em>HOPE I HELPED!!!</em>
<h2>Answer:</h2>
At 189 K volume = 32.0 cm
As volume of gas is directly proportional to temperature.
As the temperature increase the volume of gas will also increase.
so
Volume at 1 K = 32/189
Volume at 242 K = 32/189 * 242 = 40.97 cm.
Gas occupy 40.97 cm volume at 242 K.
D because strong bases ( and 14 is a strong base ) will make a strong acid neutral
The segment of the myocardial conduction framework that has the quickest rate of unconstrained depolarization is the S-A node.Depolarization goes through particular conduction pathways from the S-A hub to the A-V hub. This atrial depolarization happens at a most extreme rate of 0.3 m/sec
