The model below shows a carbide ion.

8 light grey and 6 dark grey balls sit at the center with 2 concentric black rings around them. The inner ring has 2 medium grey balls on it, and the outer ring has 8 medium grey balls on it. At bottom, a dark grey ball = +1, a light grey ball = 0, a medium grey ball = negative 1.

What could be done to change this carbide ion to a neutral carbon atom?

remove 2 electrons
add 2 electrons
remove 4 electrons
add 4 electrons

An observer that stands still as the electron moves by him, will observe

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
