Calculate percentage change in mass for chip 5

The correct answer is - 14.41%.

Explanation:

Given:

The initial mass of chip 5 -

end mass of chip 5 -

Percent Change in Mass =  /

Formula used:

Mass Difference= Final Mass- Initial Mass

Percent Change in Mass = (Mass Difference/Initial Mass) *100

Solution:

Putting the value in the formula:

Mass Difference = 2.15 - 1.84

= 0.31

Percent Change in Mass = (0.31/2.15)*100

= 14.41

Thus, the correct answer is - 14.41.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
