Passing an electric current through a certain substance produces oxygen and sulfur?
The substance is likely sulfuric acid (H2SO4). When an electric current passes through sulfuric acid during the process of electrolysis, water molecules in the acid are split into oxygen gas (O2) and sulfur.
How ozone can be obtained from oxygen?
Ozone can be obtained from oxygen by passing oxygen gas through an electric field or by exposing it to ultraviolet light, which causes some of the oxygen molecules (O2) to break apart and recombine into ozone (O3). This process usually takes place in ozone generators that are specifically designed for producing ozone gas.
What is a nonmetal element that sublimes?
Iodine is a nonmetal element that can sublime, meaning it can change directly from a solid to a gas without passing through a liquid phase.
Which of the following element ability to undergo sublimation?
Element iodine has the ability to undergo sublimation, which is the process of transitioning from a solid directly to a gas without passing through the liquid phase.
Which of the element is sublimes on heating?
One example of an element that sublimes on heating is iodine. When solid iodine is heated, it directly changes into a gas without passing through a liquid phase.
Passing an electric current through a certain substance produces oxygen and sulfur This substance cannot be a?
This substance cannot be water, because passing an electric current through water, in a process called electrolysis, produces hydrogen and oxygen gas, not oxygen and sulfur.
What process do car headlights use to emit light?
Electric Discharge- the process of emitting light because of electricity passing through a gas.
Is the heating element on a stove a chemical reaction?
No, the heating element on a stove works based on the conversion of electrical energy into heat through electrical resistance. It is a physical process rather than a chemical reaction.
What happens when an electric current is passed through the gas of vapor of an element?
When an electric current is passed through a gas or vapor of an element, it can cause the gas or vapor to ionize and emit light. This process is known as a gas discharge or glow discharge and is commonly seen in neon signs or fluorescent lights. The color of the light emitted depends on the element present in the gas or vapor.
What is the energy transfer in an electric cooker?
In an electric cooker, electrical energy is transferred into heat energy through resistance in the heating element. The electrical current passing through the element encounters resistance, which generates heat as a byproduct. This heat energy is then used for cooking food.
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
Why crook tube is called discharge tube?
A Crookes tube is called a discharge tube because it operates by passing an electric current through a gas or vacuum, causing the gas to ionize and emit light or radiation. The term "discharge" refers to the process of the gas being excited and emitting radiation when the electric current passes through it in the tube.
What will be value of flux if the surface does not enclose any charge?
If the surface does not enclose any charge, the electric flux through the surface will be zero. This is because electric flux is a measure of the total electric field passing through a surface, and if there are no charges within the surface, there will be no electric field passing through it.
What is a arc?
discharge: electrical conduction through a gas in an applied electric field
What is meant by total normal electric induction over a surface?
Total normal electric induction over a surface refers to the total electric flux passing through the surface when the electric field is perpendicular to the surface. It is a measure of the total electric field passing through the surface and is calculated by the dot product of the electric field and the surface area vector.
Compare and contrast an electric discharge with an electric current?
An electric discharge is the sudden flow of electricity through a gas, liquid, or vacuum due to a buildup of charge, often resulting in a visible spark. In contrast, an electric current is a continuous flow of electric charge through a conductor. While both involve the movement of charged particles, the key difference is that an electric discharge is a temporary and often localized event, whereas an electric current is a sustained, directed flow of charge.
Passing an electric current through a certain substance produces oxygen and sulfur?
The substance is likely sulfuric acid (H2SO4). When an electric current passes through sulfuric acid during the process of electrolysis, water molecules in the acid are split into oxygen gas (O2) and sulfur.
