Based on the description of the demonstration, were the bubbles that formed more dense than the surround-
ing water, or less dense than the surrounding water?
F. More dense; the bubbles sank to the bottom after
formation.
G. More dense; the bubbles floated to the surface of
the beaker after formation.
H. Less dense; the bubbles sank to the bottom after
formation.
J. Less dense; the bubbles floated to the surface after
formation.

How does a large body of water, such as the ocean, influence climate?

Alidded glass container is filled with a colored gas. after a period of time, it is observed that the gas is uniformly spread throughout the box and that the movement has slowed considerably. next, a warm iron plate is carefully placed under the box. why is there resumed movement of the gas in the container?

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
