Answer:
No, CCl₄ is 4 covalent C-Cl single bonds with a Tetrahedral geometry.
Explanation:l
For resonance structures to exist the molecule must have alternating single-double bonds. H₂C = CH - CH₃ <=> H₃C - CH = CH₂ resents a simple compound with a resonance structure system. This means that the π-bond electrons are distributed across all carbons in the molecular backbone. I would recommend internet searching for Danial Weeks 'Pushing Electrons' for a comprehensive review of molecular resonance structures. It is a brief, but easy to follow treatment of simple to complex structures containing resonance systems.
Hope this helps. Doc :-)
Answer:
It declined drastically
Explanation:
The moths were active at night and rested by day on white birch trees, where they were effectively camouflaged from predators.
However, as the city became more industrialized, the trees were covered with black soot from the factories.
The white moths lost their camouflage, so their population declined drastically, as their predators could now find them more easily.
Answer:
Sunlight and water (D)
Explanation:
Sunlight and water are two of the many abiotic factors that may be present in a particular environment. All other factors mentioned in the choices are biotic factors. Producers are plants; decomposers are fungi and bacteria
Answer:
50
Explanation:
so you'll have to apply Newton's 2nd law which is F=ma and then substitute the values that you already have in the question as in, the force is 200 and you'll have to find the acceleration by working it out which is 4m/s² and then find the mass by dividing 200 by 4 so the actual mass is 50kg ✌️❤️
Answer:
A transition metal
Explanation:
The metal is classified as a transition metal or transition element.
In particular, this atom is Copper it has an atomic number of 29 which we know by the number of protons.
The number of protons in an atom is the same as the atomic number.
- The element can be found in the d-block on the periodic table.
- Generally, it is classified as a transition metal.
- A neutral atom of this element has 29 electrons.
