An example of force that acts at distance is gravity and an example of contact force is pushing a chair across the room
Answer:
True, polar covalent bond
Explanation:
A covalent bond is one of the types of the chemical bond which is formed when the electrons are shared between the two atoms.
Based on the magnitude of the sharing of electrons between atoms two types of covalent bonds are formed which are: pure covalent bond in which the electrons are shared equally whereas the polar covalent bond in which the electrons are shared unequally between two atoms.
Since there is a type of covalent bond formed which has unequal sharing of electrons called polar covalent bond therefore true is the correct answer.
C! Because animal cells don’t have a cell wall! Have fun in Science!
