Answer:
Yes a bowling ball made of matter.
Explanation:
T = 20 % : 20 / 100 = 0.2
m1 = solute
m2 = Solvent
T = m1 / m1 + m2
0.2 = 500 g / 500 g + m2
0.2 * ( 500 + m2 ) = 500
0.2 * 500 + 0.2 m2 = 500
100 + 0.2 m2 = 500
0.2 m2 = 500 - 100
0.2 m2 = 400
m2 = 400 / 0.2
m2 = 2000 g of water

Answer:
Titration curves for strong and weak acids illustrating the proper choice of acid-base indicator. Any of the three indicators will exhibit a reasonably sharp color change at the equivalence point of the strong acid titration, but only phenolphthalein is suitable for use in the weak acid titration.
Explanation:
bacterial growth
Explanation:
Excessive bacterial growth is one of the example of a natural process that causes water pollution.
Pollution is the undesired concentration or harmful introduction of a particular body into the environment and causes harm overall.
- Pollution can result from both natural and anthropogenic sources.
- Anthropogenic causes of pollution are the most common due to activities of human beings.
- Natural causes of pollution results from the activities of nature in itself.
- From the given options, the bacterial growth is an natural process of pollution.
