The balanced chemical equation for powdered quartz (SiO2) reacting with powdered magnesium (Mg) when heated is: 2Mg + SiO2 -> 2MgO + Si. This reaction produces magnesium oxide (MgO) and silicon (Si).
Yes, a torch is usually powered by both chemical and light energy. The chemical energy is stored in the batteries or fuel used to create the light, while the light energy is produced when the chemical energy is converted into light through a reaction in the bulb or LED.
Chemical work in cells is powered by the energy produced from chemical reactions, specifically the breakdown of molecules such as glucose through processes like cellular respiration. This energy is captured in the form of ATP (adenosine triphosphate) and utilized to drive cellular processes such as protein synthesis, active transport, and muscle contraction.
No, watches do not contain chemical energy. Watches are typically powered by batteries or mechanical movements that convert energy from winding or movement into powering the watch.
No chemical process could provide the energy that the sun does for as long as it has. At the sun's mass and energy output, any chemical process would have exhausted its supply in a few hundred to a few thousand years. The sun has maintained roughly the same energy output for several billion years.
One common example is a battery-powered device, where the chemical energy stored in the battery is converted to electrical energy to power the device. Another example is a fuel cell, where chemical reactions between fuel and an oxidizing agent produce electrical energy.
No. Gasoline will work in the dark. Gasoline is powered by the chemical reaction that causes the flames when ignited.
Most moving vans are powered by burning either gasoline or diesel fuel; in either case, it's chemical energy.
It is a physical change

The way things glow is because some chemical compounds absorb light that is high powered and release it in a low powered way which we see glowing.
the energy transfer is from chemical to electrical to radiant
In a Diesel powered car, chemical energy powers the car. Chemical energy heats food on a gas cooker. Chemical energy delivers electrical energy in a battery. Chemical energy powers a living organism.
A battery-powered radio operates on electrical energy stored in a chemical form within the battery. When the battery is connected to the radio, a chemical reaction releases stored energy in the form of electrical current to power the radio's components.
Talking is powered by chemical energy derived from the food you've eaten.
the conversions are solar to chemical to light to heat
Chemical energy is converted into mechanical energy.
