A carbon forms one bond to an X atom plus three more bonds to three hydrogen atoms. If the hybridization to X has 81% p-character, what is the H-C-X bond angle in degrees to the nearest tenth of a degree? Hint: recall our discussion of Bent's rule and Coulson's directionality theorem. To determine the LaTeX: \lambdaλH value, consider the "conservation of p-character" rule, which states that the sum from i = 1 to 4 of LaTeX: \lambdaλi/(1 + LaTeX: \lambdaλi) = 3. Thus, LaTeX: \lambdaλH = 2 + 3/LaTeX: \lambdaλX.

Me! last question, and i'm stuck! write the algebraic expression that models the word phrase. the product of 2 divided by the number h and 8 more than the number k

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
