The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

The observation that is inconsistent with the ideal gas equation is; "When temperature is held constant and volume increases, the pressure increases."
Boyle's law describes the relationship between the pressure and volume of ideal gas. Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Hence, the statement that "When temperature is held constant and volume increases, the pressure increases." does not agree with Boyle's law therefore it is inconsistent with the ideal gas law.
Answer:
It will change weather patterns and destroy ecosystems.
Explanation:
Carbon dioxide, while not being the most power, is the most common greenhouse gas. A greenhouse gas helps to trap longwave radiation from leaving the Earth’s atmosphere and is enhancing global warming. We say enhanced global warming due to the Earth warming through natural reasons too. Several changes occur due to this temperature increase. Sea ice melting causes freshwater to enter the sea. An increase in sea levels can cause coastal flooding, increased erosion and a higher frequency and power of storms. Water density is linked to salinity. By introducing more freshwater the salinity decreases in the north and south of the Earth. If the oceanic currents change this will cause the weather to become more extreme during seasonal changes in many regions around the world. While humans can adapt their living conditions to suit the climate, many animals and plants can not. Therefore, enhanced global warming will cause the loss of many ecosystems around the world, including coral reefs.
