- (Note: please give me solution within one hour)When defining a problem, you should divide the problem into three separate components. What are these components?the mass of magnesium chloride produced when 1,5 g of magnesium reacts completely with dilute hydrochloric acid. b. the volume of hydrogen gas produced, at STP, when 17,75 g of hydrochloric acid reacts completely with magnesium. (5) (5) [17) Question 5 5. A toy missile (mass 500 g) is launched with a speed of 12 m-s from a platform (at position A) which is 3 m above the ground. It reaches a maximum height at position B, then falls back down to the ground passing position A and landing at position D. [The diagram is not drawn to scale.] Ignore the effects of air resistance. 5.1 Define kinetic energy. (2) 5.2 Calculate the initial kinetic energy of the missile. (4) 5.3 Define mechanical energy. 5.4 Calculate the initial mechanical energy of the missile. 5.5 State the law of conservation of mechanical energy. 5.6 Calculate the maximum height reached by the missile above the ground. 5.7 Determine the speed of the missile just before it hits the ground at position D.
