Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.
Answer:
I'm a bit confused on where the question is. Perhaps re-write it in the comments? I'd love to help but this seems more like an answer than a question xD
Explanation:
Yes. They are called compound machines because two or more simple machines were combined to create it.
Nitrogen Dioxide is the Answer. If any doubt leave a comment
Potential energy as the basket ball has no net movement so it thus cannot be kinetic
Also since the objects height off the ground has increased its gravitational potential energy will increase
As GPE= height*mass*gfs
So (gravitational) potential energy increases as there is now a height above zero
