Explain why the following structure is incorrect

Answers

Answer 1

Answer:

there is too many electrons around the shell

Explanation:

Answer 2

Carbon atoms must bond with 4 other atoms in this structure one of the carbons only has 3 bonds with the other atoms.
Oxygen has to bond to two other atoms so the C-O bond should be a double bond to fulfil both of their bonding rules.
Hydrogen can only bond to one other atom, therefore it cannot make a double bond so that bond must be a single bond. (Carbon there is also bonding to five atoms so changing it to a single bond will fulfil both of their bonding rules).

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of vanadium is 23. The electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³. The noble gas electronic configuration of vanadium is [Ar]3d³4s². 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals.

How do lions obtain the carbon they need?

by eating animals that have carbon-based molecules stored in their bodies
by breathing it in from the atmosphere in the form of carbon dioxide
by absorbing carbon-based molecules through their skin from the soil
by drinking water that contains carbon dioxide

Answers

Answer:

Explanation:

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.

What are Consumers?

Heterotrophs are known as consumers because they consume producers or other consumers. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.

Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.

Therefore, Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.

Help Please this is hard define:Money Supply-Counterfeit- fiat currency-specie currency-Inflation-Deflation-Deficit spending-Interest-principal-net pay-gross pay-federal reserve bank- Answer NOW!The day had been one of those unbearable ones, when every sound had set her teeth on edge like chalk creaking on a blackboard, when every word her father or mother said to her or did not say to her seemed an intentional injustice. And of course it would happen, as the end to such a day, that just as the sun went down the back of the mountain and the long twilight began, she noticed that Rollie was not around.Tense with exasperationshe would simply explode if Mother got goingshe began to call him in a carefully casual tone: "Here, Rollie! He-re, boy! Want to go for a walk, Rollie?" Whistling to him cheerfully, her heart full of wrath at the way the world treated her, she made the rounds of his haunts; the corner of the woodshed, where he liked to curl up on the wool of Father's discarded old windbreaker; the hay barn, the cow barn, the sunny spot on the side porchno Rollie.Perhaps he had sneaked upstairs to lie on her bed where he was not supposed to gonot that she would have minded! That rule was a part of Mother's fussiness, part too of Mother's bossiness. It was her bed, wasn't it? But was she allowed the say-so about it? Not on your life. They told her she could have things the way she wanted in her own room, now she was in her teens, buther heart raged against the unfairness as she took the stairs stormily, two steps at a time, her pigtails flopping up and down on her back. If Rollie was on her bed, she was just going to let him stay right there, and Mother could shake her head and mumble all she wanted to. But he was not there. The bedspread and pillow were crumpled, but not from his weight. Earlier that afternoon, she had flung herself down to cry there. And then she couldn't. Every nerve in her had been twanging, but she couldn't cry. She could only lie there, her hands doubled up hard, furious that she had nothing to cry about. Not really. She was too big to cry just over Father's having said to her severely, "I told you if I let you take the chess set you were to put it away when you got through with it. One of the pawns was on the floor of our bedroom this morning. I stepped on it. If I'd had my shoes on, I'd have broken it."Well, he had told her to be sure to put them away. And although she had forgotten and left them, he hadn't forbidden her ever to take the set again. No, the instant she thought about that, she knew she couldn't cry about it. She could be, and she was, in a rage about the way Father kept on talking, long after she'd got his point, "It's not that I care so much about the chess set," he said, just leaning with all his weight on being right, "it's because if you don't learn how to take care of things, you yourself will suffer for it later . . . .
