The particles of objects have
both kinetic and potential energy because these forces are drive by the force
of motion or stillness of an object. Potential energy is the a type of energy
which an object possess however without motion. Kinetic energy in the other
hand, is the energy in motion or if the object moves along from one space to
another with respect to time. They both have these two energies by the presence
of atoms in these entities.
Answer:
D) 
Explanation:
Carbon.
The electronic configuration is -
Thus, 2s orbital is fully filled and p orbital can singly filled 3 electrons. Thus, Carbon has 2 singly occupied orbitals.
But in methane, 
it forms 4 bonds. So, 1 electron each from 2s orbital jumps to the next orbital in the p subshell.
Thus, the configuration is:-
Thus, the valence electron configuration is:-
Answer: made up of an infinite number of indestructible atoms in unpredictable motion.
Answer:
76.25cm
Explanation:
38cm + 56cm +97cm +114cm = 305cm
305cm÷4 = 76.25cm
i. When an acid reacts with metal, a salt and hydrogen are produced:
ii. When oxygen and metal react, metal oxide forms also known as rust
iii. Acid and water produce hydroxide ions
