The anion sbf4− does not obey the octet rule. draw its lewis structure and state the type of octet-rule exception. indicate the values of nonzero formal charges and include lone pair electrons.
Answers
Answer:
SEE EXPLANATION
Explanation:
The ion SbF4^- is octahedral in shape. In this compound, Sb which is the central atom in SbF4^- has an expanded octet. This means that it has more than eight electrons in its outermost shell thereby violating the octet rule. Hence the type of violation to the octet rule shown by the compound is expanded octet.
The Sb central atom has a formal charge of -1 as shown in the image attached to this answer.

A sample of sulfur dioxide occupies a volume of 6052 mL at 352 K and 892 mm Hg. What volume will the sulfur dioxide occupy at STP?
Answers
Answer:
5511.99 mL
Explanation:
Given data
Volume V1= 6052 mL
Temperature T1= 352K
Pressure P1= 892 mm Hg
At STP the parameters of gas are
Temperature T2= 273.15 K
Pressure P2= 760 mmHg
Applying the gas equation
P1V1/T1= P2V2/T2
Substitute to find V2 we have
892*6052/352= 760*V2/273.15
5398384/352= 760*V2/273.15
15336.31= 760*V2/273.15
Cross multiply
15336.31*273.15= 760*V2
4189113.0765= 760*V2
4189113.0765/760= V2
V2= 5511.99 mL
Hence the volume at STP is 5511.99 mL

In earthquake-prone areas, engineers design buildings that are resistant to earthquake damage. Here’s a diagram of an earthquake-resistant building in Japan. Explain how features A, B, and C help protect the building from earthquake damage. In your explanation, describe how you could model each feature using marshmallows and toothpicks.
Answers
Answer:
In this earthquake-resistant building, two steel supports in the shape of an X (A) help to reinforce walls. Concrete walls with steel bars in them (B) lessen any rocking movements. Shock absorbers (C) take up some of the building’s kinetic energy during a quake. I could use the toothpicks as the two steel in the shape of an X. The concrete walls and the shock absorbers would be the marshmallows.
Features shown by points A, B & C are reinforce walls, concrete walls and shock absorbers respectively.
What is earthquake?Earthquake is a kind of natural disaster in which an intense shaing of the earth's outermost layer takes place.
According to the image following points we will consider as:
Two steel supports in the shape of an X (A) help to reinforce walls in this earthquake-resistant structure.Any rocking movements are reduced by concrete walls with steel bars (B).During a quake, shock absorbers (C) absorb some of the kinetic energy of the building.We can use the toothpicks in the shape of X as the two steel and concrete walls & the shock absorbers as the marshmallows.
Hence, marshmallows are used as the concrete walls and toothpicks are used as two steel rods.

A 1.0 g sample of which substance contains the largest
number of molecules?
Answers
Answer:
Hydrogen (since this is all the info I'm working with)
Explanation:
Since we need to know how which substance has the most amount of molecules, we would need to look at the Atomic masses of these elements. Hydrogen has an atomic mass of 1.01g/mol whereas something like oxygen has an atomic mass of 16.00g/mol. Judging this, we can determine since a mole is made up of 6.02*10^23 molecules(Avogadro's number), and we have 1/1.01grams of hydrogen, we can deduce that Hydrogen would contain the largest amount of molecules

If I have an unknown quantity of gas at a pressure of 204.83 kPa, a volume of 27.88 liters, and a temperature of 8.76°C , how many moles of gas do I have?
Answers
Answer:
700
Explanation:
How to find
Multiply the volume and pressure and divide the product by the temperature and the molar gas constant to calculate the moles of the hydrogen gas.
Solve: 204.83 × 27.88 / 8.76 = 651.901872146
Which is 651.90
In the nearest hundredths, the moles of gas is 700
In describing weather completely, it is important to include, among other aspects, air pressure, precipitation, and humidity. Which of the following statements is false?
Wind is the movement of air that results from differences in air pressure.
Precipitation is a form of water that falls to Earth’s surface from the clouds.
Air typically moves from areas of lower pressure to areas of higher pressure.
When the temperature of the air cools to the dew point, the air is saturated, and water droplets will form.
Answers
Answer:
The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.
Explanation:
The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.
Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.
Answer:
Air typically moves from areas of lower pressure to areas of higher pressure.

A sample of air starts at STP. The volume and moles remains the same, what happens to the pressure if the temperature changes to 317 K?
show steps
Answers
Answer:
Pressure increases to 1.16 atm if the temperature changes to 317 K.
Explanation:
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
On the other hand, Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically indicates that the quotient between pressure and temperature is constant:
[tex]\frac{P}{T}=k[/tex]
Studying an initial state 1 and a final state 2 is fulfilled:
[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]
In this case:
P1= 1 atmT1= 0 C= 273 KP2= ?T2= 317 KReplacing:
[tex]\frac{1 atm}{273 K} =\frac{P2}{317 K}[/tex]
Solving:
[tex]P2=317 K*\frac{1 atm}{273 K}[/tex]
P2= 1.16 atm
Pressure increases to 1.16 atm if the temperature changes to 317 K.

A farmer wants to build a pond for her cows. What step must she take in order to build the pond?
A. Dig into the zone of aeration.
B. Place a permeable material on the ground.
C. Keep the soil moist.
D. Place an impermeable material on the ground.
Answers
Answer:
Option A:
Dig into the zone of aeration
Explanation:
Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.
Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.

What is Energy?The ability to do work is called energy.
The Einstein's formula can be used to find the energy released. Energy is the product of mass and the velocity of light in a vacuum squared.
Given that the mass is 0.05 kg and speed of light in vacuum is 3×10⁸ m/s.

The effects of each kind of radiation is different on the molecules.
Explanation:
Microwave causes molecules that have two opposing poles to spin rapidly due to absorption of the electromagnetic radiation waves. When molecules absorb Infrared radiation, changes occur from a ground vibrational state to an excited vibrational state. When the visible light is absorbed by molecule, the electron is excited and goes to an orbital of higher energy than the lower energy. Ultraviolet radiation turns the stable molecule into a reactive species.
