Answer:
[HI] = 0.097 M
Explanation:
Let's consider the following reaction.
2 HI(g) ⇄ H₂(g) + I₂(g)
The order of reaction for HI is 1. Thus, we can calculate the concentration of HI ([HI]) at certain time using the following expression:
ln [HI] = ln [HI]₀ - k. t
where,
[HI]₀ is the initial concentration of HI
k is the rate constant
t is the time elapsed
When [HI]₀ = 0.440 M and t = 0.210 s, the concentration of HI is
ln [HI] = ln (0.440) - 7.21 s⁻¹ × 0.210 s
ln [HI] = -2.33
[HI] = 0.097 M
Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
Quantitative data is defined as the data that can be counts in number or can be measured in numbers. There are two main types of quantitative data : discreate data and the continuous data. examples are age , date, distance , weight etc. so, the countable and measurable quantities in numbers is quantitative data. Wavelength here is measured in numbers . so, wavelength is the quantitative data.
Thus, Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.

The result of acid on rain on buildings and bridges would be decay and rotting, the chipping and loss of cement.
Answer:
4.
Explanation:
I believe that #4 best shows the runoff in the system. We see 2/3 which is precipertation falling and 4 shows this water running off the mountains into the ocean.
