True because it actually formed I know
The chemical equation would be:
2NO(g) + O2(g) --> 2NO2 (g)
<span>At equilibrium state, the partial pressure of the gases would be as follows : </span>
<span>NO = 522 - 2x </span>
<span>O2 = 421 - x </span>
<span>NO2 = 2x </span>
<span>- - - - - - - - - - - - -</span>
<span>943 - x = 748 </span>
<span>x = 195</span>
Calculating for Kp,
<span>Kp = (NO2)^2/ ((NO)^2 * (O2)) </span>
<span>Kp = (2 * 195)^2/ ((522 - 2 * 195)^2 * (421 - 195)) </span>
<span>Kp = 0.0386 </span>
A geomagnetic storm (commonly referred to as a solar storm) is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth's magnetic field.
Solar flares, coronal mass ejections, high-speed solar wind, and solar energetic particles are all forms of solar activity.
Answer:
Explanation:
Total weight of 5 rings
= 18 x 5
= 90 g
silver = 10% of 90 g
= 9 g
gold = 81 g
Let silver added = x gm
Total weight = 90 +x
75% of (90+x) is gold
= 3/4 x (90+x)g is gold
So 3/4 x (90+x) = 81
(90+x) = 81 x 4 / 3
= 108
x = 18 g
silver to be added = 18g .
