I don’t get it? haha

Final answer:

The frequency of the light emitted by the laser pointer is approximately 5.64 x 10ⁱ⁴ Hz, as calculated using the speed of light and the specific wavelength of the light.

Explanation:

To calculate the frequency of the light emitted by the laser pointer, you can use the equation c = fλ, where c represents the speed of light in vacuum (approximately 3.00 × 10⁸ m/s), f is the desired frequency, and λ represents the given wavelength of the light (in this case, 5.32 x 10⁻⁷ m).

By rearranging the equation to solve for frequency (f = c/λ), you can substitute in the given values: f = (3.00 × 10⁸ m/s) / (5.32 x 10⁻⁷ m), which yields a frequency of approximately 5.64 x 10ⁱ⁴ Hz. Therefore, the frequency of the light emitted by the laser pointer is about 5.64 x 10ⁿ⁴ Hz.

It's important to understand that light acts as a wave, and every color of light has a unique frequency, which correlates with its wavelength. The wavelength and frequency of light determine many its characteristics, including the color we perceive.

Answer:

975.56×10²³ molecules

Explanation:

Given data:

Number of molecules of C₂H₆ = 4.88×10²⁵

Number of molecules of CO₂ produced  =  ?

Solution:

Chemical equation:

2C₂H₆  + 7O₂     →      4CO₂ + 6H₂O

Number of moles of C₂H₆:

1 mole = 6.022×10²³ molecules

4.88×10²⁵  molecules×1mol/6.022×10²³ molecules

0.81×10² mol

81 mol

Now we will compare the moles of C₂H₆ with CO₂.

                     C₂H₆          :             CO₂

                          2           :               4

                           81         :           4/2×81 = 162 mol

Number of molecules of CO₂:

1 mole = 6.022×10²³ molecules

162 mol ×6.022×10²³ molecules / 1 mol

975.56×10²³ molecules
