when the elements mg and cl form an ionic bond, mg loses electron(s) from the 3s orbital to form the mg2 cation. cl gains electron(s) in the 3p orbital to form the cl– anion. since the total number of electrons lost always equals the total number of electrons gained, the compound formed will contain mg2 ion(s) for every cl– ion(s). fill in the blanks with the appropriate numbers.

the answer for apex is the lowest

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
