Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible for us to relate the rate of formation of C and the rate of consumption of B as shown below:

Thus, we solve for the rate of change of B as shown below:

Best regards!
Answer:
Filtration is a process in which insoluble matter is separated from a liquid. Filtration is a separation process in which a mixture is passed through a filter that allows one component to pass-through but blocks another component from passing through because of its matter and consistency. Heterogeneous mixtures can be separated into their respective constituents. For example, a mixture of mud and water can be separated through filtration process easily, because water being liquid will pass through the filter paper easily but the mud will not because of it being solid
Yes, because beryllium is less dense and harder than oxygen.
<u>Given:</u>
Frequency (ν) = 319 THz
<u>To determine:</u>
The wavelength corresponding to the given frequency
<u>Explanation:</u>
Wavelength (λ) and Frequency(ν) are related as:
λ = c/ν
where c = speed of light = 3*10⁸ m/s
Now:
SI unit of frequency is Hertz (Hz) also expressed as cycles per second
i.e 1 Hz = 1 s⁻¹
1 Terahertz (THz) = 10¹² Hz
therefore the given frequency ν = 319 *10¹² s⁻¹
λ = 3 * 10⁸ ms⁻¹/319 *10¹² s⁻¹ = 940 * 10⁻⁹ m
since 1 nanometer (nm) = 10⁻⁹ m
The wavelength is λ = 940 nm
Ans: The infrared wavelength = 940 nm
