Answer:
Bond points will go astray from their perfect values agreeing to the run the show that solitary sets repulse other electrons more unequivocally than holding sets. In spite of the fact that solitary sets are clearly littler than molecules, they got to be closer to the core of an molecule than a holding combine.
which molecule is a branched alkane
a) trans-2-pentane
b) nonane
c) 3-methylhexane
d) 2-nonyne
Answer:
The answer is c
Explanation:
Because it is
3-methylhexane is the molecule that is a branched alkane. Therefore, the correct option is option C.
What is alkane?Alkanes, often known as paraffin, are acyclic saturated hydrocarbons in organic science. In other terms, an alkane is made up of carbon and hydrogen atoms that organise themselves in a tree-like arrangement with only single carbon-carbon bonds. Alkanes have the chemical formula CnH2n+2 in general.
Methanogenic bacteria generate methane, and certain long-chain alkanes have pheromone-like properties in some animal species or serve as safeguarding waxes in some plants and fungus. However, the majority of alkanes have little biological action. 3-methylhexane is the molecule that is a branched alkane.
Therefore, the correct option is option C.

Answer:
124225.91 g of Na₃PO₄
Explanation:
From the question given above, the following data were obtained:
Number of atoms of Na₃PO₄ = 4.56×10²⁶ atoms
Mass of Na₃PO₄ =?
From Avogadro's hypothesis,
6.02×10²³ atoms = 1 mole of Na₃PO₄
Next, we shall determine the mass of 1 mole of Na₃PO₄. This can be obtained as follow:
1 mole of Na₃PO₄ = (23×3) + 31 + (16×4)
= 69 + 31 + 64
= 164 g
Thus,
6.02×10²³ atoms = 164 g of Na₃PO₄
Finally, we shall determine the mass of Na₃PO₄ that contains 4.56×10²⁶ atoms. This can be obtained as follow:
6.02×10²³ atoms = 164 g of Na₃PO₄
Therefore,
4.56×10²⁶ atoms = (4.56×10²⁶ × 164)/6.02×10²³
4.56×10²⁶ atoms = 124225.91 g of Na₃PO₄
Therefore, 124225.91 g of Na₃PO₄ contains 4.56×10²⁶ atoms
The sun radiates energy towards the ______ surface and some of this radiant energy is in the form of ________.
Answer:
Earth; heat.
Explanation:
Radiation can be defined as the flow, transmission or emission of energy in the form of atomic and subatomic particles and waves through a material medium or space.
Solar radiation is a form of electromagnetic radiation emitted by the sun on the earth's surface as ultraviolet, infrared and visible light.
Hence, the sun radiates energy towards the earth surface and some of this radiant energy is in the form of heat. Radiation is generally considered to be the least important mode of the transportation of heat from one point to another in planet earth.

Answer:
A device designed to transmit electromagnetic waves through the air should be developed.
In order to meet the requirement a device is designed to transmit electromagnetic waves through the air should be developed.
What are electromagnetic waves?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.
How is the problem for Spots In ""One Morning Dragonville"" different from Wise Woman’s problem in this folk tale?.
Answer:
Spots was unable to find his missing spot while the wise woman had pieces of the fallen sky with missing patches. The missing spot was part of Spot's skin and he was desperate to find it while the pieces of fallen sky did not belong to the Wise Woman and she calmly solved her problem.
Explanation:
In the fairy tale Dragonville, Spots was unable to find his missing brown spot. The spots were a part of Spot's body and it made him sad to lose a part of his body. The pieces of fallen sky were not a part of the Wise Woman's body and she easily attached bright lights to the missing patches of fallen sky bought to her by the children.
Spots seemed desperate to find a solution to his problem unlike the Wise Woman who calmly resolved the issue of the missing patches.
