Answer:
Arrhenius Base
Explanation:
"NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. ... Acids provide the H+ ion; bases provide the OH- ion; and these ions combine to form water."

Answer:
21.1cm or 10.1cm
Explanation:
Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.
This is this:
15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm
Or this:
15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm
