Answer:
The right answer is A. Matter is preserved throughout the combustion of wood.
Explanation:
A key principle regarding matter suggests that the mass prior to a reaction equals the mass afterward.
According to Joan's experiment, she found that the quantity of carbon atoms stays at 840 during the combustion process. The count of carbon atoms present in the wood initially matches the amount present in carbon dioxide once combustion completes. This illustrates that Joan's model endorses the conservation of matter principle during wood burning.
Answer:
Explanation:
For approximately 250 years, or two and a half centuries, there has been a rapid consumption of fossil fuels to satisfy human demands. These fossil fuels release significant quantities of carbon dioxide when combusted. As a result of burning these resources in factories, power plants, vehicles, and more, carbon is emitted into the atmosphere. Carbon dioxide acts as a greenhouse gas, which leads to the trapping of heat and an increase in global temperatures.
It's projected that nearly 5.5 billion tons of carbon dioxide are emitted annually due to fossil fuel combustion. This vast quantity is overwhelming for plants to convert into oxygen through photosynthesis, causing an imbalance in the carbon cycle. Consequently, more carbon dioxide is produced than can be absorbed, ultimately contributing to a rise in the planet's temperature as the excess carbon dioxide captures additional sunlight.
