QUESTION 3 QUESTION 3 A bаll, A, is thrоwn verticаlly upwаrds frоm a height, h, with a speed оf 15 m.s-1. AT THE SAME MOMENT, a second, identical ball, B, is dropped from the same height as ball A as shown in the diagram below. Both balls undergo free fall and eventually hit the ground. USE UPWARDS AS POSITIVE. 3.1 Describe the term free fall. (2) 3.2 Calculate the time it takes ball A to return to its starting point. (4) 3.3 Calculate the distance between ball A and ball B when ball A is at its maximum height. (7) 3.4 Sketch a velocity-time graph for the motion of ball A from the time it is projected until it hits the ground. Clearly show the following on your graph: • The initial speed • The time it takes to reach its maximum height • The time it takes to return to its starting point (4) 
QUESTION 4 QUESTION 4 Cоnsider the fоllоwing two reаctions with wаter. Reаction 1: NH3(g) + H2O(l)→ NH4+(aq) + OH-(aq) Reaction 2: HCl(g) + H2O(l) → Cl-(aq) + H3O+(aq) 4.1 Define the term bonding pair. (2) 4.2 Draw the Lewis structure for ammonia. (2) 4.3 How many lone-pair electrons are on the central atom of a water molecule? (1) 4.4 Identify the substance in Reaction 2 that can form a dative covalent bond when reacting with an acid. (1) 4.5 Draw the Lewis structures to show the formation of the dative covalent bond in the substance identified in Reaction 2 in Question 4.4. (2) 4.6 Write down the shape of the NH3 molecule. (1) 4.7 Although the molecules of HCl and H2 have the same shape, HCl is polar, while H2 is non-polar. Give a reason for the difference in molecular polarity. (2)
