<span>The reason why it is easiest to assume the first step is slow is because that would be your rate determining step and would give you the rate law given in the problem. So you take the two compounds from the rate law given and put them as your two reactants in your first step:
NO2 + F2 ---> NO2F + F (all gases)
Your next step needs to make sense for your overall reaction. And you also need to have an intermediate which in this case will be F:
F + NO2 ---> NO2F (again all gases) This is the fast step.
Your intermediate cancels out to give you your overall equation:
2NO2 + F2 ---> 2NO2F (all gases)</span>
Answer:
c. electrical neutrality.
Explanation:
A <em>crystalline solid</em><em> possesses a rigid and long-range order; its atoms, molecules, or ions occupy specific positions.</em> The arrangement of such particles in a crystalline solid is such that the net attractive intermolecular forces are at their maximum.
Ionic crystals, particularly, have two important characteristics:
(1) They are composed of charged species.
(2) Anions and cations are generally quite different in size.
The forces holding the atoms together are electrostatic attractions. Examples of these types of crystals include NaCl, LiF, MgO, CaCO₃.
<u>Since they are composed of anions and cations, in stoichiometric amount, they are to be said electrically neutral.</u>
Answer:
i think that the wet cloth will keep the coolness inside the water instead of evaporating and getting warm
Explanation:
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an atom to attract the shared pair of electrons towards itself whenever a bond is formed.
This property increases as we move from left to right across a period because the number of charge on the nucleus gets increased and electrons are attracted more towards the nucleus.
This property decreases as we move from top to bottom in a group because the electrons get add up in the new shells which make them further away from the nucleus.
Thus, the correct answer is Option A.
