Answer:
Explanation:
Polar bonds also often contribute to a net dipole moment of a molecule. This basically means that there are partial charges that make a molecule overall polar. One example might be water: in H20, oxygen is very electronegative, and hydrogen is less so. This means that oxygen is more negative and hydrogen is more positive. This is why water is cohesive (can stick together): The positive ends stick to the negative ends.
To solve this we must be knowing each and every concept related to polar molecule. Therefore, polar and nonpolar molecules are covalent compound.
What is polar molecule?A polar molecule is a type of chemical compound where there is an uneven distribution of electrons among the covalently bound atoms.
The term "polarity" refers to how unlike two molecules' electrical poles are from one another. If they are quite dissimilar, the species is said to be an extremely polar molecule.
Because of the more symmetrical distribution of the electrons, non-polar molecules do not have a lot of charges on their opposing sides. The fees are all offset by one another. Polar and nonpolar molecules are covalent compound.
Therefore, polar and nonpolar molecules are covalent compound.

WILL GIVE BRAINIEST is C6H1005 + O2 → CO2 + H2O balanced?
Answer:
No! The balanced equation is given below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Explanation:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
The equation above is not balanced. It can be balance as illustrated below:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 at the right side. It can be balance by 6 in front of CO₂ as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on right side. It can be balance by 5 in front of H₂O as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O
There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by 6 in front of O₂ as illustrated below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Now, the equation is balanced.

What is polymerization reaction?High-molecular-weight compounds known as polymers are created by the aggregation of several smaller molecules known as monomers. Polymers make up the natural and manmade fibres used in clothes as well as the polymers that have revolutionised society.
Two fundamental methods for creating polymers exist: (a) joining small molecules together by an addition reaction, and (b) joining molecules while getting rid of a stable small molecule like water. Condensation processes, which combine addition and elimination reactions, are what this later type of polymerization is known as. H-O* + CH[tex]_3[/tex]-CH[tex]_3[/tex] → H-O-CH[tex]_2[/tex]-CH[tex]_2[/tex]* is an example of an initiation phase for an addition polymerization reaction.

Based on the image below, what is the displacement of the sound wave for Sound A + B at 0.1025 seconds?
A. -0.3316
B.0.3316
C.0.6255
D.1.6162
Answer:
The displacement of the sound wave for Sound A + B at 0.1025 is;
D. 1.6162
Explanation:
The sum of the displacement of two sound waves is given by the principle of superposition as follows;
y(x, t) = [tex]y_m[/tex]·sin(k·x - ω·t) + [tex]y_m[/tex]·sin(k·x - ω·t + ∅)
Therefore, by the property of the superposition of waves, the amplitudes of linear waves are added linearly when they meet at the same point at a the same time
The given parameters for the wave are;
The time at which the value of the wave amplitude are given, t = 0.1025 seconds
The displacement of the sound wave A at the given time, "t" is A = 0.9739
The displacement of the sound wave B at the given time "t" is B = 0.6423
Therefore, the displacement of the sound A + B = 0.9739 + 0.6423 = 1.6162

What is evaporation?
Evaporation is a sort of vaporization that occurs on a liquid's surface when it transitions from a liquid to a gas.
Evaporation is a separation technique that can be used to separate components of a combination including a decomposed solid in a liquid. The liquid gets evaporated, which means it is converted from a liquid to a gas. This frequently necessitates the use of heat. The solid will be all that remains after the liquid has entirely evaporated.

The burning of a sample of propane generated 1 04.6 kJ of heat. All of this heat was used to heat 500.0 g of water that had an initial temperature of 20.0/C. What was the final temperature of the water?
Answer: 70.0°C
Explanation:
Quantity of heat = Mass * Specific heat * Change in temperature
Quantity of heat = 104.6 KJ
Mass = 500.0 g
Specific heat of water is 4.18 J/g°C
Change in temperature assuming final temperature is x = x - 20
Units should be in grams and joules:
104,600 = 500 * 4.18 * (x - 20)
104,600 = 2,090 * (x - 20)
x - 20 = 104,600/2,090
x = 104,600/2,090 + 20
x = 69.8
= 70.0°C

Further explanationGiven
Combustion of menthol
Required
The empirical formula
Solution
Mass of CO₂ produced : 0.449 g
mass C = 12/44 x 0.449 = 0.122
Mass water produced : 0.1840 g
Mass H = 2.1/18 x 0.1840 = 0.02
Mass O in menthol :
=mass sample - (mass C+mass H)
= 0.1595 - (0.122+0.02)
= 0.0175
Mol ratio C : H : O in sample :
= 0.122/12 : 0.02/1 : 0.0175/16
= 0.01 : 0.02 : 0.001
= 10 : 20 : 1
