Answer:
We learned that waterhas three states: ice is the solid state, watervapor is the gaseous state, and wateris the liquid state. When water is heatedit evaporates, which means it turns into watervapor and expands. Secondly, does water expand when heated?
Explanation:
Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is
the point which there is stoichiometrically equivalent amounts of acid and
base. <span>
<span>Chemist can draw pH curve (graph
showing the change in pH of a solution, which is being titrated) for
titration and determine equivalence point.</span></span>
They are volcanoes
The difference between a quiet and explosive eruption is the silica content. In a quiet eruption, the magma is low in silica, allowing the magma to flow out gently. In an explosive eruption, the magma is high in silica, which causes the magma to be thick and sticky.
