In an experiment, two unknown compounds (one an alcohol and the other an amine) of
equal molecular mass were heated. The result of the experiment shows that Compound A
boiled at a lower temperature than Compound B.
Which of the following correctly explains the identity of Compound A and why this was
the result? (4 points)
It is an amine; it contains nitrogen-hydrogen bonds that are less polar and oxygen-hydrogen
bonds.
It is an alcohol; it contains nitrogen-hydrogen bonds that are less polar and oxygen-hydrogen
bonds.
It is an alcohol; it contains oxygen-hydrogen bonds that are less polar and nitrogen-hydrogen
bonds
It is an amine; it contains oxygen-hydrogen bonds that are less polar and nitrogen-hydrogen
bonds.

In pea plants, the allele for tallness (t) is dominant to the allele for shortness (t). in the cross between a tall pea plant and a short pea plant shown below, what is the probability that the resulting offspring will be tall? whats the percent

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
