Does the amount of magnesium ribbon burned affect how much magnesium oxide is produced?

Yes, the amount of magnesium ribbon burned does affect how much magnesium oxide is produced. More magnesium ribbon burned will result in more magnesium oxide being produced since the reaction between magnesium and oxygen is stoichiometric, meaning it requires a certain ratio of reactants to produce a set amount of product.


The suns energy is generated at its?

The sun's energy is generated at its core through the process of nuclear fusion, where hydrogen atoms fuse together to form helium, releasing immense amounts of energy in the form of heat and light. This energy then travels through the sun's layers before being emitted as sunlight into space.


How do Calcium Pyruvate supplements increase energy?

Calcium pyruvate increases your energy by boosting your metabolism. When your metabolism is boosted, fewer of your consumed starches and sugars are stored as fat as opposed to being burned off by your body. When more starch and sugar is burned off by your metabolism, your energy increases.


What energy rich substance is being produced in the mitochondria?

Adenosine triphosphate (ATP) is the energy-rich substance produced in the mitochondria through the process of cellular respiration. ATP is the primary energy currency of the cell and is used to power various cellular processes.


What are the conditions under which oxygen reacts with hydrogen to produce water. Oxygen supports combustion and hydrogen is a good fuel but water is a good extinguisher - why?

It is very good question indeed. Volume by volume two parts of hydrogen will burn in one part of oxygen.(Formula being 2H2 + O2 = H2O.) Mass for mass 212=4 to 16*2=32. 1 and 16 being mass number of hydrogen and oxygen. So 4 is to 32 means 1 is to 8 would be proportion mass by mass. After burning of hydrogen in oxygen, large amount of heat is produced and water is formed. To burn the hydrogen in oxygen you have to ignite the reaction in the form of spark, otherwise both of them will not burn and will remain as a mixture. Onceignitedthen further energy will be given by burning of gases. Now as water is already burn out product, it can not burn again. By burning wood, you get ash. You can not 'burn' the ash. So water is like 'ash' already burned out. And it consume lot of energy to get evaporated and easily available. So you use it to extinguish fire.

What organic compounds are produced when materials containing carbon and hydrogen are burned?

Hydrocarbon is an organic compound which is entirely made up of hydrogen and carbon. Hydrocarbons are the main source of the world’s electric energy and heat because of the energy produced when they are burned.


Why is water produced when hydrogen is burned?

The combustion of hydrogen requires oxygen, which is supplied by the surrounding air. When hydrogen is combusted, it reacts with oxygen in the equation: 2H2 + O2 --> 2H2O with water (H2O) being the product


What fuel is being burned by main sequence stars?

Where is the sun's energy produced?

The energy in the Sun is primarily produced in the core, where nuclear fusion reactions convert hydrogen into helium, releasing vast amounts of energy in the process. This energy then travels outward through the Sun's layers before being emitted as sunlight into space.

When coal is burned energy is being converted to energy?

When coal is burned, chemical energy stored in the coal is converted into heat energy. This heat energy is then used to produce steam, which drives turbines to generate electricity.


What is hydrogen evolution?

Hydrogen evolution is the process in which hydrogen gas is produced by the electrolysis of water or through a chemical reaction. This process is important for producing hydrogen as a clean energy source for fuel cells and other applications.
