A light wave traveling through glass strikes the boundary with a second medium at a 45° angle and then refracts away from the boundary. What could the second medium be?
A.
Water
B.
Air
C.
Diamond
D.
Glass

Answers

Answer 1
D glass GUI dad hkmvgv d
Answer 2

Diamond has the highest refractive index, causing the light wave to refract away from the boundary.

Option (C) is correct.

The key observation is that the light wave refracts away from the boundary. This suggests that the second medium has a higher index of refraction than glass. Among the given options, diamond has the highest refractive index, making it the most likely choice.

Diamond has a refractive index of approximately 2.42, which is significantly higher than that of water, air, and glass. When light travels from a medium with a lower refractive index (such as glass) to a medium with a higher refractive index (such as diamond), it bends towards the normal line. This causes the light wave to refract away from the boundary, as described in the scenario.

Therefore, the most plausible answer is that the second medium is diamond.

5. A 5.00 g sample of an unknown substance was heated from 25.2 C to 55.1 degrees * C , and it required 133 to do so. Identify the unknown substance using the chart above.

show work please

Answers

Answer:

Aluminum

Explanation:

Given

[tex]T_1 = 25.2^oC[/tex]

[tex]T_2 = 55.1^oC[/tex]

[tex]m = 5.00g[/tex]

[tex]\triangle Q= 133J[/tex]

See attachment for chart

Required

Identify the unknown substance

To do this, we simply calculate the specific heat capacity from the given parameters using:

[tex]c = \frac{\triangle Q}{m\triangle T}[/tex]

This gives:

[tex]c = \frac{\triangle Q}{m(T_2 - T_1)}[/tex]

So, we have:

[tex]c = \frac{133J}{5.00g * (55.1C - 25.2C)}[/tex]

[tex]c = \frac{133J}{5.00g * 29.9C}[/tex]

[tex]c = \frac{133J}{149.5gC}[/tex]

[tex]c = 0.89\ J/gC[/tex]

From the attached chart, we have:

[tex]Al(s) = 0.89\ J/gC[/tex] --- The specific heat capacity of Aluminum

Hence, the unknown substance is Aluminum

What is the percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water?

73.1%
36.7%
26.9%
24.2%

Answers

Answer:

26.9%

Explanation:

I just took the test! :)

The percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.

How to calculate percentage by mass?

The percentage by mass of a solution can be calculated by dividing the mass of the solute by the mass of the solvent, then, multiplied by 100.

percent by mass = mass of solute/mass of solvent × 100

According to this question, 36.0 grams of HCl is dissolved in 98.0 grams of water. The percentage by mass is calculated as follows:

percent by mass = 36g/98g × 100

percent by mass = 36.7%.

Therefore, the percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.

Answers

Answer:

3

Explanation:

remember the equation percentage yield = actual/ theoretical yield as

4.20/4.88 x 100

86.065 so 86.1.

hope this make sense:)

The percentage yield of the product is 86.1%. The correct option is 3) 86.1%

Calculating percentage yield

From the question, we are to calculate the percentage yield of the product

Percentage yield can be calculated from the formula,

[tex]Percentage \ yield = \frac{Actual\ yield}{Theoretical \ yield} \times 100\%[/tex]

From the given information,

Actual yield = 4.20 g

Theoretical yield = 4.88 g

Putting the parameters into the formula, we get

[tex]Percentage \ yield = \frac{4.20}{4.88} \times 100\%[/tex]

Percentage yield = 0.86065574 × 100%

Percentage yield = 86.065574%

Percentage yield ≅ 86.1%

Hence, the percentage yield of the product is 86.1%. The correct option is 3) 86.1%

The Oyo Empire was the ancient African Kingdom is located in western Africa.

What is Oyo Empire?

The Oyo Empire prospered on regional trade and became a key facilitator in moving slaves from Africa's interior to the coast and waiting European sailing ships, with its capital at Old Oyo near the River.

The human trade was so extensive that this region of Africa became known simply as the "Slave Coast."

Finally, despite all efforts, the Oyo Empire became a protectorate of the United Kingdom in 1888; its states ceased to exist as a superpower, and it never regained its prominence in the region.

During the colonial period, however, the Yoruba were one of Africa's most urbanized groups.

Thus, the ancient African kingdom of the Oyo Empire was located in western Africa.

What is the molarity of a solution of 58.7 grams of MgCl2 in 359 ml of solution?

Answers

Answer:

1.72 M

Explanation:

Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:

Molarity = number of moles (n? ÷ volume (V)

According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.

Using mole = mass/molar mass

Molar mass of MgCl2 = 24 + 35.5(2)

= 24 + 71

= 95g/mol

mole = 58.7g ÷ 95g/mol

mole = 0.618mol

Volume of solution = 359ml = 359/1000 = 0.359L

Molarity = 0.618mol ÷ 0.359L

Molarity = 1.72 M

The volume of the solution is given below which can be calculated using the molarity formula.

d. 2.18 litres

Molarity:

It is defined as the ratio of number of moles of solute to the volume of the solution.

It is given by:

M= n/V

What information do we have?

M= 0.420M

mass = 64.0 grams

Molar Mass= 74g/mol

To find:

Volume of solution=?

Calculation for number of moles:

n= m/ M

n= 64/70

n= 0.91 moles

Molarity=  n/V

0.420 M= 0.91 moles /V

V= 0.91/ 0.420

V= 2.1768 litres

Thus, the volume of the solution is 2.18 litres.

Is the ending substance the same substance as the blue powder? What happened to the atoms of the starting substances when the ending substances formed

Answers

Answer:

Vanished completely.

Explanation:

The atoms of starting substances are transformed into the ending substances because the starting substances mixed with each other and turn into new substances. The starting substances i.e. reactants vanished completely when the ending substances means products are formed completely so we can say that the vanishing of ending substance happened when the ending substances are formed.

The ratio of atoms of potassium to atoms of oxygen is  2:1

Explanation:

As the equation given is :

The product formed is 2 moles of potassium oxide .

Amount of potassium atom in the potassium oxide  is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .

But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .

Hence , we get 4 atoms of potassium and 2 atoms of oxygen .

Ratio of potassium to oxygen atoms is -   4:2

A presión de 3atm, 7L de un gas a temperatura constante experimenta un cambio ocupando un volumen de 0,5L ¿Cuál será la presión que ejerce? ayuda

Answers

Answer:

La presión que ejerce es 42 atm.

Explanation:

La ley de Boyle relaciona la presión y el volumen y dice que  el volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión.

La ley de Boyle se expresa matemáticamente como:

P*V=k

Ahora es posible suponer que tienes un cierto volumen de gas V1 que se encuentra a una presión P1 al comienzo del experimento. Si varias el volumen de gas hasta un nuevo valor V2, entonces la presión cambiará a P2, y se cumplirá:

P1*V1= P2*V2

En este caso:

P1= 3 atmV1= 7 LP2= ?V2= 0.5 L

Reemplazando:

3 atm* 7 L= P2* 0.5 L

Resolviendo:

[tex]P2=\frac{3 atm*7 L}{0.5 L}[/tex]

P2= 42 atm

La presión que ejerce es 42 atm.
