In a laboratory, Nakisha mixes a sodium hydroxide solution with an indicator called phenolphthalein. When
combined, they create a pink solution. Nakisha wonders if mixing other solutions with phenolphthalein will also
create this pink color. How could Nakisha use the scientific inquiry process to determine whether mixing other
solutions with phenolphthalein will also create a pink color? Check all that apply.
by making qualitative observations about the sodium hydroxide and phenolphthalein in solution
by asking a classmate if sodium hydroxide turns pink when mixed with other solutions
by comparing the given solution to other familiar solutions containing phenolphthalein
by designing an experiment to test phenolphthalein with other solutions
by repeating the experiment at different temperatures

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
