How is rotting a chemical change?
garbage rotting is a chemical change because the odour becomes different which is considered a sign of chemical change.
How chemical change that garbage undergoes?
garbage rotting is a chemical change because the odour becomes different which is considered a sign of chemical change.
How many electrons when hydrogen becomes an ion?
When hydrogen becomes an ion, it typically loses one electron to form a positively charged hydrogen ion (H⁺). This process occurs because hydrogen has only one electron in its neutral state. Consequently, when it ionizes, it has zero electrons, resulting in a net positive charge.
When a low mass star first runs short of hydrogen in its core it becomes brighter because?
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
If a chemical compound becomes oxidized it?
loses electrons, increasing its oxidation state and potentially changing its chemical properties, such as color or reactivity. This process often involves the loss of hydrogen atoms or the gain of oxygen atoms.
How does hydrogen become an ion in chemical reactions?
Hydrogen becomes an ion in chemical reactions by losing its single electron, leaving behind a positively charged hydrogen ion.
Hydrofluoric acid chemical formula?
Hyrdofluoric acid has the chemical formula HF. In pure form, it is a gas, but dissolved in water it becomes a weak acid.
What is the energy of fuels that produces electricity?
The energy in fuel that produces electricity is chemical energy. By rapidly oxidizing, "burning", the carbon, hydrogen and sulfur in the fuel we produce heat. this heat is absorbed by water to produce steam to drive an engine, this engine turns an electromagnet (field rotor) inside another electromagnet (stator) to generate electricity for use. The transformation of fuel to electricity is as follows: Chemical energy to heat energy to mechanical energy to electrical energy. Only about 25% of the energy in fuel becomes electricity.
What types of energy can electricity transform into is there more than 1?
I think so. -- Use electricity to charge a battery ==> it becomes chemical energy -- Use electricity to toast bread in the toaster ==> it becomes heat energy -- Use electricity to drive a golf cart ==> it becomes kinetic energy -- Use an electric crane to lift I-beams to the second story ==> it becomes potential energy -- Use electricity to run a fan ==> it becomes wind energy -- Use electricity to operate a radio transmitter ==> it becomes radio energy -- Use electricity to bake a turkey in 10 seconds ==> it becomes microwave energy -- Use electricity to run the washing machine ==> it becomes water-wave energy -- Use electricity to film an image of a broken leg ==> it becomes x-ray energy -- Use electricity to run a particle accelerator for research ==> it becomes nuclear energy -- Use electricity to read a comic book under the covers ==> it becomes light energy -- Use electricity to play a CD on the boom-box ==> it becomes sound energy
When table salt forms from its elements is it chemical or physical change?
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
Why do we not use hydrogen?
Hydrogen is not widely used as a fuel source because it is difficult and expensive to produce, store, and transport. Additionally, hydrogen production often relies on fossil fuels or requires large amounts of electricity, which can contribute to greenhouse gas emissions. Overall, the infrastructure for hydrogen use is not as developed as for other energy sources like fossil fuels or renewables.

What are two methods for producing hydrogen?
Two methods for producing hydrogen are electrolysis, which involves using electricity to split water into hydrogen and oxygen, and steam methane reforming, which involves reacting natural gas with steam to produce hydrogen.
What do acids for in water?
Acids in water release hydrogen ions, which can react with other substances to form new compounds. This property of acids gives them their characteristic sour taste and ability to conduct electricity. Additionally, acids can initiate chemical reactions and serve as catalysts in various processes.
Metal conducts electricity better as it becomes what?
As a metal becomes colder, it generally conducts electricity more efficiently.
