Which of the following is a nonpolar molecule?
mylen [45]

<u>Answer:</u> The correct option is A) a nitrogen molecule.

<u>Explanation:</u>

Polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is not equal to 0. These molecules are formed by heteronuclear molecules.

Heteronuclear molecules are defined as the molecules which are formed by the combination of more than one type of atom having a different nucleus.

Non-polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is equal to 0. These molecules are formed by homonuclear molecules.

Homonuclear molecules are defined as the molecules which are formed by the combination of one type of atom having the same nucleus.

From the given options:

  • A) A nitrogen molecule

It is a homonuclear molecule formed by the combination of 2 nitrogen atoms

  • B) A nitrogen monoxide molecule

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 1 oxygen atoms

  • C) A linear nitrogen oxide molecule (N_2O) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 2 nitrogen and 1 oxygen atom and has some dipole moment. Thus, is considered a polar molecule

  • D) A bent nitrogen dioxide molecule (NO_2) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 2 oxygen atoms and has some dipole moment. Thus, is considered a polar molecule

Hence, the correct option is A) a nitrogen molecule.

PLEASE HELP!! 20 POINTS!
Vinvika [58]

Answer:

Energy transformation, also known as energy conversion, is the process of changing energy from one type of energy to another. In physics, energy is a quantity that provides the capacity to perform work (e.g. lifting an object) or provides heat. In addition to being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed.

The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home's air to raise its temperature.

Why both men and women could become victims of violence
ycow [4]
Because some people don't care if your a man or a woman they'll still try to harm you which is wrong cause i don't see why people have to kill each other but they do its out of bad habit and its also what they choose in life some people choose to be murders and some choose to go to work and have a family instead of being in jail for the rest of your life unless your sentenced to death. But some people don't understand a lot of things but i do well some but i do know this that when people kill someone they may feel bad but sometimes they don't they feel happy and wanna do it again so they run and try not to get caught. but life isn't fair but lets hope that the world will come around again if it ever does but its always gonna be on the news that someone is murdered.
