Answer:
C. 2.
Explanation:
The total reaction order of this reaction is second order (2). For a second order reaction ,the rate depends on two variable concentration terms which may or may not be same.
Given that:
Two reactants combine to form a product in the reaction A + B → C
The above reaction is bimolecular as two molecules are involved in the reaction.
If 
and 
are the concentrations of A and B respectively at any time t, then assuming that the reaction is of first order with respect to both A and B , the overall order is second and the reaction rate is given by:
where;
= specific rate constant for a second order reaction and becomes the rate of the reaction when both and are unity.
Here is the answer of the given question
Answer:
ionization energy is the amount of energy it takes to remove an atoms most loosely bound electron. going from the top of a group to the bottom, ionization energy decreases, as it is getting easier and easier to remove the outermost electron. As you move down a group, you add principle energy levels, which causes shielding. this means that there is decreased communication between the outermost electron and the nucleus, making it easier to remove the outer electron.
Answer:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.
