Nitrogen dioxide

CHEMISTRY STAGE 1: ISSUE INVESTIGATION In this issue investigation, the essay will be focussed on and discussing the beneficial and non-beneficial of fuel cells and associating it with fossil fuels. But first, you might query what fuel cells and fossil is? Well fuel cell is an electrochemical energy stratagem that converts hydrogen fuel as well as oxygen to produce electricity, heat and water. While on the other hand fossil fuel are the products fossils that are really old. For instance the…

climate has been one of the major factor that has greatly impacted the earth.” (Riebeek, para 1). Another definition by Maria Trimarchi simply states that “Global Warming is as a result of the long-term effects by greenhouse gas; mainly carbon dioxide…

that greenhouse gases emitted by the human population cause global warming. Greenhouse gases come from a variety of sources such as the exhaust of automobiles, and even from cattle in feedlots. The gas most responsible for global warming is carbon dioxide a waste gas emitted by most living things, which…

This is good news but the bad news still remains in play. Vehicles were a huge impact on the environment by releasing carbon dioxide into the atmosphere and destroying the ozone layer. Spending billions of dollars on the conservation movement has been a helping hand the situation but the track it is on will take numerous decades to finally eradicate and in doing so, the research…

Global warming or climate change is the gradual increase of Earth’s temperature over time, through the greenhouse effect. The greenhouse effect is the rising carbon level in the atmosphere, trapping radiation, and heating the Earth. Humans are depending on fossil fuels that release these emissions. Though we have increasingly started depending on renewable resources that don’t release these harmful gases into the atmosphere, we can already see the effects today and if this doesn’t stop now the…

All organisms in an ecosystem are interconnected and play specific roles that are crucial to the entire community’s sustainability and well-being. When a single aspect of the community is taken away, it affects the rest of the organisms that inhabit the ecosystem, and usually in a way that negatively impacts the area’s biodiversity. The source of most energy on Earth comes from the Sun however, only a certain group of organisms can harness the sun’s energy and convert it into sugars and…

the earth will still continue to warm at a rapid pace due to the carbon dioxide still present in the atmosphere, mind you CO2 has a residence time in the atmosphere of over 100 years. The most viable solutions to this problem have been geo-engineering methods, some of which are extremely clever, but also extremely costly and impractical. A lot of the proposed solutions have to do with removing the already present carbon dioxide gas through methods that involve installing stations equipped with…

It is on the local news or found in the newspaper. It is in the air that people breathe every single day. However, many humans are still not aware of the harmful effects of global warming. Carbon is emitted into the air daily because of the burning of fossil fuels. Eventually, we will run out of fossil fuels. Then what happens? There are plenty of clean alternatives that put little to no greenhouse gas into the atmosphere. One small switch at a time could save a population of polar bears or even…

destruction of the environment. The natural gas option that was previously seen as more climate friendly, is actually seriously harming it. Fracking has been proven to be linked to leaks of methane 23 times more potent in greenhouse gas than carbon dioxide. A recent study by the National Oceanic and Atmospheric Administration on Opposing Viewpoints, monitoring gas wells in Weld County, Colorado, estimated that 4 percent of the methane produced by these wells is escaping into the atmosphere. The…

reaction that requires water, carbon dioxide and energy from the sun to produce glucose and oxygen. In the process of photosynthesis water is oxidised and carbon dioxide is reduced. The process of photosynthesis consists of two parts; a light-dependent reaction and a light-independent reaction. In the light dependent reaction the energy from light moves the electrons from a photosystem into to high energy state. In the light dependent reaction carbon dioxide and a few other compounds are…
