When an ebonite stick is rubbed with a woolen cloth, electrons are transferred from the wool to the stick, giving it a surplus of electrons. Because neutral materials have equal numbers of electrons and protons to balance out their charge, the rubbed stick possesses a net negative static charge.Know More
The woolen cloth becomes positively charged by the same magnitude that the stick becomes negatively charged to conserve the total charge in both materials. These charges create static on the surfaces of the two materials, so the resulting phenomenon is called static electricity. Electrification by friction is one of three ways that static charge on the surface of a material can be induced.
When a material is connected to a source of positive or negative potential, such as the terminals of the battery, the material gains the same potential as the source. This process is called charging by conduction.
When a charged material is brought close to an isolated neutral material without contact, it causes an opposite charge to form on the neutral material. This is called charging by induction. If the material with the induced charge is grounded, the charge dissipates to the ground either by electrons flowing into the material for a positive charge or electrons flowing into the ground for a negative charge.Learn more in Chemistry
According to the European Chemistry Thematic Network, wood reacts with oxygen when it burns. The combustion of wood produces carbon dioxide and water, which are reaction products released as gases into the atmosphere.Full Answer >
Glow stick bubbles are soap bubbles mixed with the contents of a glow stick. The glow is produced when the chemical inside the glow stick goes from a high energy state to a low energy state, releasing light in the process.Full Answer >
The Austin Community College electron transport page explains that as electrons travel down the transport chain, the electrons are transferred between protein complexes and lose energy that is used to pump protons across the mitochondrial membrane. This enables the maintenance of a proton gradient across the inner mitochondrial membrane, which in turn is used to run the ATP synthase to make the ATP that cells use for energy.Full Answer >
