A 17.4 L sample of oxygen gas (O2) was collected at a temperature of 23.0°C and a pressure of 2.18 atmospheres. What volume would the gas occupy at STP?

Answers

The volume of the gas at STP = 35.01 L

Further explanation

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

V=17.4 L

T = 23 + 273 = 296 K

P = 2.18 atm

[tex]\tt mol=n=\dfrac{PV}{RT}\\\\n=\dfrac{2.18\times 17.4}{0.082\times 296}\\\\n=1.563[/tex]

The volume of the gas occupy at STP :

[tex]\tt 1.563\times 22.4=35.01~L[/tex]

Answers

This tablet insufficient to neutralize the acid in the patient's stomach

Further explanation

Reaction

what process creates deltas?

Answers

Explanation:

A delta is a process that forms by river deposition into an ocean or marine environment.

Sediments carried by rivers in their old stage are brought near the mouth of an ocean. As the velocity of the river reduces, sediments begins to settle out. Small river tributaries breaks out into the ocean. Delta forms at an interphase between a small and large body of water. The deposited sediments forms distinct shapes as they enter the larger body of water.

what happens to the temperatures when we have direct sunlight vs indirect sunlight?

Answers

Explanation:

When we have direct sunlight, the temperature is higher compared to indirect sunlight.

Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.

Direct sunlight impacts the surface with more energy concentrated on a smaller surface area. This warms the surface more. Indirect sunlight is diffuse and spreads over a wider area. This leads to a reduction in temperature.

10. The molar mass of CS2 is 76.14 g/mol. How many grams of CS2 are present in 10.00 mol?

Answers

Answer: C

Explanation:

There are 761.4 grams of CS2 in 10.00 mol.

To calculate the amount of grams present in a given amount of moles, the molar mass of the substance must be used, as follows:

                                        [tex]m = MM \times mol[/tex]

In this way, just perform the following operation:

                           

                                          [tex]m = 76.14 \times 10[/tex]

                                         [tex]m = 761.4 grams[/tex]

Thus, there are 761.4 grams of CS2 in 10 mol of the substance.

When a hammer strikes a nail, the nail

Answers

Answer:

The nail will exert a force of equal strength in the opposite direction on the first object.

Explanation:

"According to Newton's third law of motion, when a hammer strikes and exerts force on a nail, the nail exerts a force of equal strength in the opposite direction on the first object."

Basically, if you push someone, they will fall over right?

Still, you will feel the force as you push them over, and you might stumble back while they are pinwheeling and falling into a pool.

That force is that torque when the person's weight is also pushing back at you while your force is pushing at them.
