Lewis dot structure of PSI3 with minimized formal charges

Chemistry
1 answer:
vredina [299]1 year ago
3 0

We need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

<h3>What is Lewis dot structure?</h3>

Lewis dot structure is defined as the visual representation of atoms' electrons using a diagram. It describe the bonds that exist between a molecule's lone pairs of electrons and its atoms.

A lone pair of electrons on the atom with the formal charge of 1- can typically be converted into a bonding pair that is shared with the atom that has the formal charge of 1+ in order to reduce the formal charges when they are present.

Thus, we need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

Who is responsible for the impacts of overfishing?
GarryVolchara [31]

Answer:

Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a “shame list” of countries responsible for overfishing tuna in the Pacific. According to Pew, the “Pacific 6” are responsible for 80 percent — 111,482 metric tons in 2011 — of the annual catch of bigeye tuna.

A chemist prepares a solution by dissolving 0.3 mole of CaCl2 in enough water to make 1000 mL of solution. What is the molar con
Rasek [7]
CaCl_{2} dissolves in water to give Ca^{2+} and Cl^{-} ions according to the following reaction:

CaCl_{2}  -------->  Ca^{2+}  + 2Cl^{-}

So, according to the above reaction, 1 mole of CaCl_{2} produce 2 moles of Cl^{-} ion,

So, 0.3 mole will give = 0.3 x 2 = 0.6 moles of  Cl^{-} ion

So, Molar concentration = \frac{0.6moles}{1L} = 0.6

Note: 1L = 1000mL

Which choice tells how energy is transferred between the atmosphere and hydrosphere? runoff and condensation precipitation and e
4vir4ik [10]

Answer:

correct answer is  precipitation and evaporation

Explanation:

solution

correct answer is  precipitation and evaporation  because in the evaporation process of water cycle, the atmosphere is directly interact with the hydrosphere as water changes from liquid into vapor or  gas form

and Precipitation is the process when water that may be in the form of snow or hail or rain etc that is fall from the cloud into the open sky

so correct answer is  precipitation and evaporation

A SCUBA tank can normally hold 18 liters of gas at 3000 psi. How many liters of gas would this be equivalent to if the gas were
NikAS [45]

Liters of gas at 14.7 psi: 3674 L

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

pV=const.

where

p is the gas pressure

V is its volume

This law can also be rewritten as

p_1 V_1 = p_2 V_2

Where:

p_1 = 3000 psi is the initial pressure of the gas

V_1 = 18 L is the initial volume of the gas

p_2 = 14.7 psi is the final pressure of the gas

V_2 is the final volume

Therefore, we can calculate the volume of gas corresponding to 14.7 psi of pressure:

V_2=\frac{p_1 V_1}{p_2}=\frac{(3000)(18)}{14.7}=3674 L
