Solution: (I) Let the distance between the points (-1, 2) and (2, 3) be d, then. d = √ [ (2 – ( –1)) 2 + (3 – 2) 2] = √ [9 + 1] = √10 units. (II) Let the distance between the points (0, 1) and (6, –1) be d, then. d = √ [ (6 – 0) 2 + ( –1 – 1) 2] = √ [36 + 4] = √40 = 2√10 units.
26 cze 2019 · Chemical reactions have the same number of atoms before the reaction as after the reaction. Balancing chemical equations is a basic skill in chemistry and testing yourself helps retain important information. This collection of ten chemistry test questions will give you practice in how to balance chemical reactions.
