An object will remain at rest or maintain constant, straight-line motion unless acted on by a force that is .inertialb. balancedc. unbalancedd. along a straight linecan someone explain it somehow for me? .

C.unbalanced
Newton's Law explains that an object continues at constant speed due to the net force acting on the object being zero. When the net force is not zero (unbalanced), then there is a net force and the object will accelerate.

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for
