Hypothetical elements x and y form a molecule xy2, in which both y atoms are bonded to atom x (and not to one another). the x—x distance in the elemental form of x is 2.04 å, and the y—y distance in elemental y is 1.68 å. what would you predict for the x—y distance in the xy2 molecule?

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
