The reaction between magnesium (Mg) and oxygen (O2) forms magnesium oxide (MgO). a. Write a balanced chemical equation to represent this reaction.
b. Identify the type of reaction this represents.

2 Mg + O2 = 2MgO

Type: Synthesis

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
