Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number. The boiling and melting points increase consistently as atomic number increases.

The boiling and melting points decrease consistently as atomic number increases.

The boiling and melting points go up and down as the atomic number increases and there is no clear trend.

What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

What effect does a decrease in temperature have on the overall rate of a chemical reaction? a decrease in temperature decreases . the reaction rate will
