Answer:
(a) CH3CH2CH2CH2CH3(l)
(b) CH3CH2OH(l)
- Dipole-dipole interaction
- Dispersion forces
- Hydrogen bonding
(c) H2CO(l)
(d) O2(l)
Explanation:
Dispersion forces are those forces that occur between two non polar molecules.They form the weakest bonds.Here electrons of one molecule is attracted to the nucleus of the other molecule. Example are;
- Interaction of two methyl (-CH₃) group
- Interaction between nitrogen gas , N₂ molecules
- Interaction between oxygen gas ,O₂ molecules
Dipole-Dipole interaction happens when two polar molecules interact.Positive charges in one molecule is attracted to negative charge of another molecule.Examples
- Chloroform (CHCl₃)
- Ammonia (NH₃)
Hydrogen bonding are created when an hydrogen atom bonded to an electronegative atom is attracted to a another electronegative atom.Example is the hydrogen bond between oxygen atom and hydrogen is water (H₂O).
Answer:
Argon gas
Explanation:
Argon is a chemical element. Its symbol is Ar. It is the noble gas which is odorless and colorless. It is one of the most abundant gas on the earth after oxygen and nitrogen.
Argon gas is most commonly used in the panes of the thermal windows. It has 34 percent lower thermal conductivity as compared to the air and so it is more comfortable to used instead of the air. It is an inert gas and does not react with other things. It is not harmful.
Answer:
where ni = no. of moles of any compound and mi = molecular mass of any ... Sulphur : (w) O.C. + HNO3 → H2SO4 + BaCl2 → (w1) BaSO4 ... 0.365 g of pure HCl gas is dissolved in 50 mL of solution. ... yield is 80% then calculate the amount of Cl2 produced. the amount of water ... Fe2O3 + 3SO3 Fe2(SO4)3
Explanation:
did that help if not please contact me in the comments.
All organic material has decaying Carbon-14 in it. But if plants and animals are still alive, they constantly replace the supply of Carbon in their systems so the amount of Carbon 14 in the system stays constant. Once a plant or animal dies, the Carbon is no longer regenerated and so the Carbon 14 starts to decay.
Answer:
No it is not a physics because in this there is about classification of element so it is in chemistry that's why it is not physics.
