Which statements accurately describe Dmitri Mendeleev’s contributions to the development of the periodic table? Check all that apply. 1.Mendeleev wrote the first modern chemistry textbook. 2.Mendeleev produced the first orderly arrangement of known elements. 3.Mendeleev ordered the elements by increasing atomic number. 4.Mendeleev used patterns to predict undiscovered elements. 5.Mendeleev accounted for variations resulting from isotopes.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
