What is the vsepr theory for an ammonia molecule?
The VSEPR theory for an ammonia (NH3) molecule predicts that the molecule has a trigonal pyramidal shape. This is because the nitrogen atom has one lone pair of electrons, causing the bond angles to be slightly less than the ideal 109.5 degrees.
How do lone pairs in p orbitals affect the molecular geometry of a compound?
Lone pairs in p orbitals can affect the molecular geometry of a compound by influencing the bond angles and overall shape of the molecule. The presence of lone pairs can cause repulsion between electron pairs, leading to distortions in the molecule's geometry. This can result in deviations from the ideal bond angles predicted by the VSEPR theory, ultimately affecting the overall shape of the molecule.
What is the bond angle of nitrogen trifuoride?
Nitrogen trifluoride is a planar molecule. The nitrogen atom is directly bonded with three fluorine atoms on the same plane. According to the VSEPR theory, it has a bond angle of 120 degrees. I think there is confusion with boron trifluoride. The actual measured bond angle of NF3 is 102.50 In VSEPR theory (Valence shell electron pair theory) the number of electron pairs around the nitrogen are counted and there are four. If all of pairs were identical as in methane for instance, then the bond angle would be the tetrahedral angle of 109.5 0 however the lone pair decreases the other angles slightly
When the central atom of a molecule has unshared electrons the bond angles will?
When the central atom of a molecule has unshared electrons, the bond angles will be less than the ideal angles for a given molecular geometry. This is because the unshared electrons create additional repulsion, pushing the bonded atoms closer together and reducing the bond angles.
What most idealized bond angle pf3 sbr2 chcl3 or cs2?
The most idealized bond angle would be in CS2, which has a linear molecular geometry with a bond angle of 180 degrees. PF3, SBr2, and CHCl3 have trigonal pyramidal, angular, and tetrahedral geometries, respectively, which deviate from the ideal angles due to lone pair repulsions.

How does Voltaire agree with the US democratic ideal?
Voltaire shared a belief in the importance of individual freedoms and liberties, which aligns with the democratic ideal of the United States. He championed freedom of speech, religion, and thought, values that are foundational to American democracy. Additionally, both Voltaire and the US democratic ideal emphasize the importance of critical thinking, reason, and the pursuit of knowledge.

Example answers of what is ideal self?
The ideal self is the version of ourselves that embodies our perfect qualities, values, and characteristics. It represents the person we aspire to be, reflecting our highest potential and values. Our ideal self serves as a guide for personal growth and development, guiding us towards becoming the best version of ourselves.
What is the difference between real and ideal culture?
Ideal culture will always differ from real culture; values and norms do not describe actual behavior, as much as, they describe how much we are supposed to behave. Real culture: what actually happens in everyday life; Ideal culture: how we are supposed to behave based on cultural norms and values.
The ideal gas equation will only give correct values if the temperature is expressed in degrees?
The ideal gas equation will give correct values as long as the temperature is expressed in an appropriate temperature scale (such as Kelvin or Rankine) to maintain a consistent relationship with the other variables involved (pressure, volume, and number of moles). Expressing temperature in degrees Celsius or Fahrenheit will not give accurate results with the ideal gas equation.

What does a lone pair distort the molecular shape?
A lone pair of electrons can distort the molecular shape because it occupies space around the central atom and exerts repulsive forces on nearby bonded atoms. Unlike bonding pairs, lone pairs are localized and occupy more space, leading to adjustments in the angles between bonded atoms. This results in changes to the ideal bond angles predicted by VSEPR theory, often causing a distortion in the molecular geometry to accommodate the presence of the lone pair. Consequently, molecular shapes such as bent or trigonal pyramidal can arise from the influence of lone pairs.
What is the difference between Real and Ideal values?
Real culture is defined as what people actually do, whereas ideal culture is what people say they do. For example, tribal hunters may say that they are going to bring back monkey meat for the evening meal, but they may not succeed. Americans may tell others that they stop at eight sided traffic signs, but how often do they actually do it?
What is well conditioned triangle in surveying?
a triangle that all the angles within it are between 30 and 120 degrees. an equilateral triangle is ideal
What is examples of ideal self?
Examples of an ideal self could include being confident, successful, kind, compassionate, healthy, and fulfilled. It can be unique to each individual based on their values, goals, and aspirations.
