Answer:
The length and strength of the C-H bond are different for ethine, ethylene and ethane due to the difference between the s characters (sp 3, sp 2, sp) in each chemical structure, which gives stronger bonds. For example, the length of the C-H bond in ethino is 1.06Å, which is also less than in ethane (1.09Å) or ethylene (1.08Å).
Explanation:
Clouds are a source of Infrared Radiation. When cloud coverage increases, the infrared radiation also increases. So the clouds basically act as space heaters. This emits energy towards the ground, which is what makes cloudy nights warmer. While with clear sky’s all the heat from the day just escapes back into the atmosphere so the temperatures will be colder.
Answer:
The ionic bond in NaCl are stronger than the stronger than the dispersion forces in HCl.
The hydrogen bonds in H2O are stronger than the dispersion forces in H2Se
Hydrogen bonds in NH3 are stronger than the dipole-dipole attractions in PH3.
Hydrogen bonds in HF are stronger than the dispersion forces in F2
Explanation:
Ionic bonds occur in molecules with high differences in their electronegative value where there are actual transfer of electrons. HCl has a bond which is involved in the sharing of electrons.
Hydrogen bonds are present in H2O which is stronger than the dispersion forces.
PH3 is a larger molecule with greater dispersion forces than ammonia, NH3 has very polar N-H bonds leading to strong hydrogen bonding. This dominant intermolecular force results in a greater attraction between NH3 molecules than there is between PH3 molecules.
F2 is a non-polar molecule, therefore they have London dispersion forces between molecules while HF has a hydrogen bond because F is highly electronegative.
The mass of Water in Calorimeter is approximately 118 grams, here is the solution:
Iodine&chlorine contain negative charge.so they are anion.When we do electrolysis those charge go to anod&become ion.
