The rate law of a reaction is rate = k[D][X]. The units of the rate constant are ________.
bogdanovich [222]

Answer:

D

Explanation:

Hello!

Since the rate must have the following units: mol/(L*s), the suitable units for k, considering that the term [D] [X] leads to mol^2/(L^2) (it means a second order kinetic law), are L/(mol*s), nevertheless, that answer isn't in the given options.

Composition of the nuclei of two atomic species A and B are given below:
Inessa [10]

Explanation:

(a) mass number = atomic number + number of neutrons

(the atomic number is the number of protons of an element)

mass number of A = 11 + 12 = 23

mass number of B = 17 + 18 = 35

(b) +1 and -1, respectively

(c) A+ + B- → AB (the first plus sign and the minus sign are superscripts)

(b) Briefly explain how the presence of charged ions in ionic solids such as NaCl(s) helps to explain why NaCl(s) is a soluble i
bonufazy [111]

Answer:

-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.

Explanation:

-Sodium Chloride has positively charged sodium ions, Na^+ and negatively charged chloride ions, Cl^-.

-Water on the other hand has positively charged Hydrogen ions,H^+ and negatively charged Oxygen ions, O^{2-} due to the difference in electroneganivity.

-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:

NaCl+H_2O->NaOH+HCL\\\\Na^++Cl^-+H_2O->Na^++(OH)^-+H^++Cl^-

What is the most common way an earthquake changes Earth's landforms? A
g100num [7]

<u>Answer</u>:

"The earthquake shakes the position of land" is the most common way an earthquake changes Earth's land forms

<u>Explanation</u>:

Most of the times earthquake has been found to be making drastic reforms over the surface. With respect to the movement of ground other surface effects includes variation in the flow of groundwater, landslides and also in the direction flow change of mudflow. It affects the buildings, bridges, pipelines and railways and other important structures. the ground movement takes place due to the movement of underground rocks which found to be breaking near the faults. This release energy that further leads to movement of the tectonic plates. The generation of seismic wave from the energy.
