What is the ratio of the number of molecules in 1 L of CO2(g) to the number of molecules in 1 L of CH4(g) at the same temperature and pressure? * 2 points 1:1 3:5 1:2 2:4

Answers

Answer:

1:1

Explanation:

Based on Avogadro's law, the volume of an ideal gas is directly proportional to the moles (Or number of molecules) presents of this gas under constant temperature.

The volume of the gas is independent to the nature of the gas

Using this law, we can change the state as:

X number of molecules of CO₂ in X number of molecules of CH₄ (Because are occupying the same volume). That means the ratio of molecules is:

1:1

A gas has an initial volume of 15 L. If the temperature increases from 330 K to 450 K, what is the new volume.

Answers

Answer:

20.(45)L or about 20.4545L

Explanation:

PV = nRT

Where:

P - pressure

V - volume

n - number of particle moles

R - a constant

T - temperature in K

We can assume the P and n (and definitely R) stay the same, so we infer that

[tex]V_1 = \frac{nRT_1}{P} = 15L\\V_2 = \frac{nRT_2}{P}\\V_1 / V_2 = \frac{nRT_1}{P} / \frac{nRT_2}{P} = \frac{T_1}{T_2}\\\\15L / V_2 = \frac{330K}{450K} = \frac{11}{15}\\\\V_2 = 15L \cdot \frac{15}{11} = 20.(45)L[/tex]

What is gas law?

Gas law gave the relation between pressure, volume and temperature.

It can be expressed as:

PV = nRT.

where, P is pressure, R is gas constant and T is temperature.

Calculation of volume by using gas law.

1) Given data:

n = 1 mol

T = 25 degree C = 25 + 273 =

P = 100 kpa

Volume can be determined by the gas law.

PV = nRT

V = nRT/P

V = 1 × 8.31 × 278 / 100

V = 23.10 L

2) It is known that at STP 1 mol of any gas volume will be 22.4 L.

Therefore, the correct answer will be option (c).

What is refraction of sound wave ?

An important case in which sound waves change form or spread out is called refraction. This phenomenon affects the bending of a sound wave owing to changes in the wave's speed.

Refraction is the reason ocean waves near a shore parallel to the beach and why glass lenses can be used to focus light waves.

If the air above the earth is warmed than that at the surface, sound will be change shape back downward toward the surface by refraction. Sound propagates in all directions from a point source.

Thus, option A, C and D are correct.

A 10.150g sample of a compound known to contain phosphorus and oxygen yields 5.717 g of oxygen. Find the empirical formula of the compound

Answers

Answer: The empirical formula is [tex]P_2O_5[/tex]

Explanation:

Mass of O = 5.717 g

Mass of P= (10.150-5.717) g = 4.433 g  

Step 1 : convert given masses into moles.

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{5.717g}{16g/mole}=0.357moles[/tex]

Moles of P=[tex]\frac{\text{ given mass of P}}{\text{ molar mass of P}}= \frac{4.433g}{31g/mole}=0.143moles[/tex]  

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For O = [tex]\frac{0.357}{0.143}=2.5[/tex]  

For P =[tex]\frac{0.143}{0.143}=1[/tex]

The ratio is to be converted to whole number

Thus whole number ratio of O : P = [tex]2.5\times 2:1\times 2=5: 2[/tex]

Hence the empirical formula is [tex]P_2O_5[/tex]

Answers

1)Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays.

2)The image produced by a convex mirror is always virtual, and located behind the mirror. When the object is far away from the mirror the image is upright and located at the focal point.

3)When the object is located at the focal point, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.
