Identifying polar regions within molecules is a very useful skill for chemists that us to think about the strength of intermolecular forces and molecular interactions, but it also us to understand the chemical properties of substances like acids and bases. here we investigate the molecular structures of the common weak acid, acetic acid, and one of the more common weak bases, methyl amine. acetic acid methyl amine 8th attempt part 1 (1 point)feedbacksee hintsee periodic table what is the molecular formula for acetic acid? $$ part 2 (1 point)feedbacksee hint draw the lewis structure for acetic acid. part 3 (1 point)feedbacksee hint which bond in the acetic acid molecule is the most polar? choose one: a. o–h bond b. c–o bond c. c=o bond d. c–c bond e. c–h bond part 4 (1 point)feedbacksee hint what is the molecular formula for methyl amine? $$ part 5 (1 point)feedbacksee hint draw the lewis structure for methyl amine. part 6 (1 point)feedbacksee hint which bond in the methyl amine molecule is the most polar? choose one: a. c–n bond b. c–h bond c. n–h bond

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?
