Answer true (t) or false (f). Make sure to only enter your answer as a lower case t for true or a lower case f for false. The final answer, bolded and underlined, in the following calculation has been reported with the correct number of significant figures: 2.3 + 8.259 = 10.559 = 11 [1] A bulls eye with darts can be used to represent accuracy and precision of data. The image in Figure 1 shows three arrows very close together on the second ring of a three-ring bulls eye. The data represented in Figure 1 can best be classified as accurate but not precise. [2] Figure 1: “The molecule of glucose contains 6 C atoms, 12 H atoms, and 6 O atoms.” The underlined and bolded portion in this statement is an example of the symbolic domain used in chemistry. [3] Pancake syrup is a homogenous mixture. [4] Buckminsterfullerene is a type of fullerene with the formula C₆₀. Buckminsterfullerene is a compound. [5] The atomic mass of Kr is 36. [6] The subatomic particle of the neutron has a +1 charge. [7] The compound of CO is an ionic compound. [8] The chemical formula below is an example of an empirical formula.
