The strength of an acid or a base is determined by the
of the substance in solution. the acid dissociation
constant, is a quantitative measure of acid strength. a
strong acid has a much ka than a weak acid. the ka of
an acid is determined from measured values.
hydrochloric acid and sulfuric acid are ionized in
solution and are acids. ethanoic acid, which is only
about 1 percent ionized, is a acid. magnesium hydroxide
and calcium hydroxide are strong
weak bases react with to form the hydroxide ion
and the conjugate of the base. concentration in solution
does not affect whether an acid or a base is or weak.

Which of the following best supports the concept that genetic information is passed on to offspring from both of their parents, not just one?

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
