Answer:
B
Explanation:
To calculate questions like this, you need to make use of the equation below:
ν = c / λ
ν is the frequency, c is the speed of light, and λ is the wavelength
ν = c / λ
2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)
λ = 0.122 m = B

I think it means the reaction doesn't have any intermediate phases - the order doesn't change, and it moves at the same rate, it doesn't speed up or slow down at any time
Density of a substance is given by dividing its mass with volume.
The volume of the block is 3.5 cm× 2.0 cm ×1.5 cm = 10.5 cm³
thus density = 34.56 g/ 10.5 cm³
= 3.291 g/cm³
Answer:
d. diethyl alcohol
Explanation:
When ketones undergo reduction, they produce 2° alcohol, and 3-pentanone will produce dimethl alcohol as the secondary (2°) alcohol
