The rate law for 2 NO2 +F2⇔ 2NO2 F is
rate = k[ NO2][F2]
<h3>explanation</h3>
The order with respect to reactant is the exponent is raised in the rate law. Since the reaction above is a second order overall and is a first order in F2 then it must be also a first order in NO2 therefore the rate raw = K[No2][F2]
Question: What is shown on the photo above?
Choices: A) An aquifer B) A sinkhole C) A watershed D) Karst topography
Answer: <u>It's C) A watershed because A. is where the water is underground, B. is a sinkhole and it has a big hole that is big or sometimes small, and D. Is where it has a little crack in it and it goes underground. </u>

Answer:
Empirical formula is C₃H₄O
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
.
Given data:
Percentage of hydrogen = 7.14%
Percentage of carbon = 64.3%
Percentage of oxygen = 28.6%
Empirical formula = ?
Solution:
Number of gram atoms of H = 7.14 / 1.01 = 7.1
Number of gram atoms of O = 28.6 / 16 = 1.8
Number of gram atoms of C = 64.3 / 12 = 5.4
Atomic ratio:
C : H : O
5.4/1.8 : 7.1/1.8 : 1.8/1.8
3 : 4 : 1
C : H : O = 3 : 4 : 1
Empirical formula is C₃H₄O.
