Explanation:
Answer:
Hexane
Explanation:
This is a simple Alkane with six cabrons therefore the prefix "Hex-" is applied. Since the molecule has no double bonds it will have the ending "-ane"
Answer:
trigonal pyramidal
Explanation:
In NF3, the nitrogen atom is sp3 hybridized. Now we must remember that according to the VSEPR theory, the number of electron pairs in the valence shell of the central atom in a molecule determines its shape.
Here, the nitrogen atom is the central atom and its outermost shell is surrounded by four electron pairs - one lone pair and three bond pairs. This means that it has a tetrahedral electron pair geometry.
However, due to the lone pair, the three fluorine atoms are arranged in a trigonal pyramidal geometry. Hence the correct shape of the molecule is trigonal pyramidal.
Petroleum stores energy from the sun and is carbon based, this characteristics make it a valuable resource.
<u>Explanation:</u>
Petroleum, a non-renewable fossil fuel has been in great demand as it makes transportation faster. Also we can convert petroleum to different types of liquefied petrol, gasoline and other igniting agents.
Fossil fuels are valuable energy sources because they contain hydrocarbon and other carbon-based materials. From light into heat into electricity, the energy saved with coal and oil arises from the sun, as they arose as plants and animals.
Along with being used as igniting agent, petroleum can also be used for generation of electricity, washing clothes in dry wash, as a lubricant in some of the automobile parts. Also it is used in sports equipment, manufacturing machines as lubricants, carpeting and other every day uses are there for petroleum.
