Answer:
b. Add NO gas
Explanation:
According with Le Chatelier´s principle, when a reactant is added the equilibrium is displaced to the product(s), to achieve the equilibrium again. Therefore, if NO is added in the reaction, it will be produced more of NO2(g).
Answer:
D only
Explanation:
The products are the stuff on the right of the yield sign so the answer is D only.
Answer:
69,632 grams
explanation
number of molecules =mass\molemass
nh3 14 +2×3=20
3.4×1024=m/20
cross multiply
grams =69,632
Answer:
Different Number of neutrons.
The flame test is commonly used to identify different metal ions by how they get excited in the presence of a flame.
Typically a nichrome wire is dipped in a solution of metal cations and then presented to a flame. The flame emits a different color than normal, depending on the type of metal cation. Each metal ion gets excited by the flame and as the electrons change energy levels they emit a photon of light, thus changing the color. Since each metal cation has unique energy levels, the colors differ depend on the metal cation.
I hope this helps.
