What evidence of chemical change is visible when electricity is run through water?
Water can be chemically changed, for instance, when an electric current is run through a sample, separating it into oxygen and hydrogen gas. Chemical change requires a chemical reaction, a process whereby the chemical properties of a substance are altered by a rearrangement of the atoms in the substance.
Added:
What is visible: it is gas bubles of hydrogen and oxygen coming out from the electrodes: O2 at the positive anode, H2 at the negative cathode.
What else can I help you with?
Does no visible change mean no chemical reaction?
Not necessarily. A lack of visible change does not always indicate the absence of a chemical reaction. Some reactions may be occurring at a molecular level and not produce a noticeable alteration in appearance. It's important to consider other evidence, such as changes in temperature, gas production, or pH level, to determine if a chemical reaction has taken place.
Approximately what percentage of the visible light that reaches Earth's producers is converted to chemical energy?
Approximately 1-2% of the visible light that reaches Earth's producers is converted to chemical energy through photosynthesis. This energy is then used by the producers to fuel their growth and metabolic processes.
What describes the visible light given off by a chemical reaction?
The visible light emitted by a chemical reaction is a type of luminescence known as chemiluminescence. It occurs when a chemical reaction produces light as a byproduct, typically as a result of excited molecules releasing energy in the form of photons in the visible range. Chemiluminescence is commonly seen in glow sticks and fireflies.
What chemical changes provide evidence that a compound has formed?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Visible formation of new compounds - A violent reaction with explosion or fire - Bubbling
Can your breath becoming visible on a cold day be a chemical change?
No, your breath becoming visible on a cold day is a physical change, not a chemical change. It simply involves the condensation of water vapor in your breath due to the colder temperatures, causing it to appear as a mist. The chemical composition of your breath remains the same.
What is visible evidence of energy passing through the water?
Visible evidence of energy passing through water can include waves, ripples, and water movement caused by wind, currents, or objects interacting with the water. Additionally, you may see changes in the color or opacity of the water due to the energy passing through it.
Can you give a sentence that has the word visible?
There was no visible evidence of tampering.
What Object that converts electricity to light?
A light bulb converts electricity into light. When electric current passes through the bulb's filament, it heats up and emits visible light.
How does electricity move through air?
Electricity only moves through the air if there are electrically charged particles in the air and a live current passed through it. It also travels in the form of static electricity (lightning).
Which is visible evidence of energy passing through water?
A wave is a good example of energy passing through water, and it is clearly visible. The crest of the wave represents the point of peak energy content, according to Bernoulli.There are other ways that energy passes through water, but these are not clearly visible. For example, when water is heated it rises because of the reduced density compared to the colder water.
What happens to the filament when electricity flows through?
When electricity flows through the filament in a light bulb, it heats up due to resistance, becoming white-hot and producing visible light. This light is what we see when we turn on a light bulb.
Why is electricity invisible?
because atoms, electrons, and neutrons are all very, very small. So they are not visible to the naked eye. However scientists can see these micro organisms with a microscope. Electricity is also visible when it sparks.
Can electricity pass through the atmosphere of earth?
Yes, electricity can pass through the Earth's atmosphere, as lightning is a natural phenomenon that demonstrates this. Lightning occurs when electrical charges build up in clouds and then discharge through the atmosphere, creating a visible bolt of electricity between clouds or from clouds to the ground.
What visible evidence do you have about the sun?
The Sun itself.
Is a type of chemical when exposed to radiation emits visible light?
is a type of chemical when exposed to radiation emits visible light.
Why can't we see electricity?
Most of our electricity is made in power stations by machines called generators. Electricity is a kind of energy and it flows into our homes, schools and towns. It happens via the cables buried beneath our feet or wires hanging over our heads.
What is the visible discharge of electricity?
It's called LIGHTNING.
