What could happen to the amount of greenhouse gases in the atmosphere if oceans continue to warm? How could this impact global c
My name is Ann [436]

The solubility of gas in water is inversely proportional to the temperature. That means cool waters can hold more gases than hot waters. So when the oceans continue to warm all the green--houses gases present in oceanic waters will be released into to the atmosphere. This would further lead to the heating up of the planet. The global climate would keep changing and the temperature of the planet would increase further. Therefore, when the oceans continue to warm the amount of green-house gases  cannot be sequestered by the oceans (as the temperatures are high) and so this would further enhance the greenhouse effect.

identify each material as a compound or a mixture. Caffeine contains hydrogen, carbon, nitrogen, and oxygen atoms in a fixed rat
vitfil [10]
Answer: caffeine is a compound.

Explanation:

1) As stated c<span>affeine contains hydrogen, carbon, nitrogen, and oxygen atoms in a fixed ratio.

2) The definition of compound is a pure substance formed by chemical bonding of two or more fifferent elements. That means a defined ratio of the elements in the compound, which conferes uniform and equal properties to every part of the compound.

Some examples of compounds are salt (NaCl), water (H2O), vinegard (CH3 COOH).

A mixture combines several elements or compounds, not bonded by chemical bonds but mixed in ratios which may vary.
