Explanation:
1.) is CH3F a hydrogen bonding? yes or no? = No, CH3F is not a hydrogen bonding beacuse the molecule lacks hydrogen atoms bonded to nitrogen, oxygen, or fluorine; ruling out hydrogen bonding.2.) is CH3F dipole-dipole interactions? Yes or no? = Yes, CH3F is a dipole-dipole interactions beacuse in it's molecule, there are no metal atoms to form ionic bonds3.) is CH3F a london dispersion forces? Yes or no?= Yes, CH3F is a london dispersion forces because in it's molecule, there are no metal atoms to form ionic bonds .The intermolecular forces present in the bonding of CH₃F are dipole-dipole interactions and London dispersion forces.
1.) No, CH₃F does not exhibit hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom such as fluorine, oxygen, or nitrogen. In CH₃F, the hydrogen atom is bonded to carbon, which is not highly electronegative.
2.) Yes, CH₃F exhibits dipole-dipole interactions. Dipole-dipole interactions occur between molecules that have permanent dipoles due to the electronegativity difference between the atoms. In CH₃F, the fluorine atom is more electronegative than the carbon and hydrogen atoms, resulting in a polar molecule with a permanent dipole moment.
3.) Yes, CH₃F exhibits London dispersion forces. London's dispersion forces, also known as Van der Waals forces, are present in all molecules and arise from temporary fluctuations in electron distribution. Although CH₃F has dipole-dipole interactions, it also experiences London dispersion forces due to the temporary shifts in electron density.
Hence, the bonding in CH₃F was explained above.

given scientific reason for Nacl dissolves in water
Answer:
Matter is made-up of minute particles. Minute particles of matter have space between them.
So, when common salt is added to water, the particles of salt get into the space between particles of water.
Hence, common salt (Table salt) dissolves in water.

A rubber ball is held 4.0 m above a concave spherical mirror with a radius of curvature of 1.5 m. At time equals zero, the ball is dropped from rest and falls along the principal axis of the mirror. How much time elapses before the ball and its image are at the same location?
The time elapsed when the ball placed above the concave mirror and the image formed would be at the same location is 0.55 s.
Image distanceThe position of the image formed is determined using the followimg mirror formula;
[tex]\frac{1}{f} = \frac{1}{v} + \frac{1}{u}[/tex]
where;
f is the focal length of the mirrorv is the image distanceu is the object distancef = R/2
f = 1.5/2
f = 0.75 m
When the ball and its image is in the same position, u = v
The position of the ball is calculated as;
[tex]\frac{1}{f} = \frac{1}{u} + \frac{1}{u} \\\\\frac{1}{f} = \frac{2}{u} \\\\u = 2f\\\\u = 2(0.75)\\\\u = 1.5 \ m[/tex]
Time of motion of the ballThe time taken for the ball to travel the caluclated distance is determined as;
h = ut + ¹/₂gt²
1.5 = 0 + ¹/₂(9.8)t²
1.5 = 4.9t²
t² = 1.5/4.9
t² = 0.306
t = 0.55 s
Thus, the time elapsed when the ball and its image are at the same location is 0.55 s.

How many grams of air are required to complete the combustion of 186 g of phosphorus (M= 31 g/mol) to diphosphorus pentoxide, assuming the air to be 23% oxygen by mass?
4P(s) + 5O2(g) — 2P2Os(s)
Answer:
1043.5 g of air to the nearest tenth.
Explanation:
4P + 5O2 ---> 2P2O5
4*31 g P reacts with 5*32 g oxygen
124 g .. .. . .... . 160g oxygen
186 g .. .. .. .. .. (160*186)/124 g oxygen
- so the mass of air required = [(160*186)/124] / 0.23
= 240 / 0.23
= 1043.5 g of air.

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Physical chemistry, and Stochiometry.
So we balance the equation as,
2Na + Cl2 ===> 2NaCl
The required reaction is as:
2Na+ Cl2 = 2NaCl
2 moles Na = 2×23 g = 46g,1 mole Cl2 = 2×35.5g=71g
Now,71g Cl2 reacts with 46g Na,
Therefore, 67.2g Cl2 reacts with 46×67.2/71= 43.54g Name
The rest Na = (55–43.54)g=11.46g
That means Cl2 is a limiting reactant.
Again,2 moles NaCl=2(23+35.5)g=117g
Then,71g Cl2 produce 117g NaCl
Therefore,67.2g Cl2 produce 117×67.2/71 = 110.74g NaCl
hence the correct option is, b.) 111 g NaCl

A: Run-off
B: Precipitation
C: Evaporation
D: Condensation
Answer:
im guessing its A run off
Explanation:
Answer: Run off
Explanation:
Wetlands have plants that clean water through. As water flows into a wetland it encounters the the plants growing there. This slows the water down making it less likely to cause erosion. The nutrient pollutants nitrogen and phosphorus are absorbed by the roots of the plants.
