Is burning methane a chemical reaction? Write the balanced equation for the combustion of 2,4-dimethylpentane. Which of the following are the general products of a combustion reaction? A. C(s), O2, H2 B. C(s), H2O, O2 C. CO2, H2 D. CO2, H2O ...
What is the starting substance in a chemical reaction? Can chemical reactions be reversed? What is an endothermic reaction? What chemical reactions produce gas? What kind of reactions are redox reactions? What kind of chemical reaction is shown: CaCO3 yields CaO + CO2?
Photosynthesis is the process used by plants, algae and somebacteriato turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) andoxygen. The chemical reaction often relies on a pigment called chlorophyll, which gives plants their green color. ...
the removal process can be a physico-chemical reaction, at the border of the atmosphere and of another compartment of the planet. CO2, for example, is reduced by photosynthesis (atmospheric/ground border), or is dissolved in the ocean then converted into bicarbonate and carbonate ions (CO2 is...
Energy stored for use elsewhere must be in some other form than electromagnetic radiation. For example, in molecular or atomic structures, made in stars, the most energy intense structural forms of molecular binding energy or nuclear binding energy, released by chemical reactions or nuclear fission ...
A‘three-way catalytic converter’ (TWC) simultaneously removes three main compounds using reduction and oxidation reactions: Reduction of nitrogen oxides (NOx) to nitrogen – NOx may be nitrous oxide (NO) or nitrogen dioxide (NO2) gases which create smog and acid rain. ...
Stoichiometry: Stoichiometry refers to the calculations made to find amount of reactants and products in a chemical reaction. Stoichiometry is based on the law of conservation of mass, where the total mass of reactants will have to produce an equal amount of products, supposing the reaction has...
The raw fat or oil must first undergo a series of chemical reactions in order to become fuel. There are a few different ways to make biodiesel, but most manufacturing facilities produce industrial biodiesel through a process called transesterification. In this process, the fat or oil is first ...
sodium bicarbonate (NaHCO3), is a chemical that can undergo adecomposition reactionwhen heated. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2)....
Chemical etching is used in semiconductor fabrication to selectively remove materials from the surface of silicon wafers. It involves exposing the wafer to a chemical solution that reacts with the targeted material, causing it to dissolve or erode. Etching is employed to create desired patterns, rem...
