Yes because I went through college and learned this
If you go by the decimal there should be 5 significant digits because 0 is a trailing zero and matters since it comes after a decimal. however if you do
6.3590 x 10 ^7 = 63590000 then you would only have 4 significant digits because there is no longer a decimal to make the zero after the 9, significant.
Hope this helps!
I believe the answer is D.
Owls are birds of prey. ... After an owl eats the small rodents, birds, and bugs that are a part of its nightly diet, its stomach cannot digest the fur, bones, teeth, feathers, and insect shells from that food. These “extra” parts are formed into a tight PELLET inside the owl and are then are later SPIT UP by the owl.
Answer:
K = [NO₂]⁴[O₂] / [N₂O₅]²
Explanation:
Based on the chemical equilibrium reaction:
2 N₂O₅(g) ⇄ 4NO₂(g) + O₂(g)
The equilibrium reaction is obtained as the ratio between the multiplication of the concentrations of the reactants over the products powered to its reaction coefficient. That is:
<h3>K = [NO₂]⁴[O₂] / [N₂O₅]²</h3>
