What is formed when calcium metal burns in air?
Calcium oxide (CaO), and calcium nitride (Ca3N2)
Why silver bromide is stored in brown bottles?
Silver bromide is sensitive to light and can degrade when exposed to it. Storing it in brown bottles helps to protect it from light exposure, which can prevent unwanted chemical reactions and maintain its quality and effectiveness for longer periods of time.
What would be produced when calcium is heated in air?
Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
Why calcium turns to red in the flame test?
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.

How does the hydrolysis of calcium carbide happen to produce an acetylene gas by means of heat?
When calcium carbide reacts with water, it undergoes hydrolysis to produce calcium hydroxide and acetylene gas. The reaction is exothermic, meaning it releases heat. This heat can further increase the rate of hydrolysis and aid in the production of acetylene gas.
Are worms sensitive to light?
Yes, they are sensitive to light.
Are plants sensitive to light?
yes plants sensitive to light
Which part of the eye is sensitive to light?
The retina at the back of the eye is light-sensitive.
Is Rabeprazole light sensitive?
Yes, rabeprazole is sensitive to light. It should be stored in its original packaging or container, away from light and moisture, to maintain its stability and effectiveness.
Is human eye sensitive to red light?

What is the name of the light-sensitive pigment in rods?
The name of the light-sensitive pigment in rods is rhodopsin.
Is there a list of light sensitive drugs?
A list of light sensitive drugs can be found in most pharmaceutical books. Many pharmacies will provide customers with a list of light sensitive drugs.
What are rods in the eye sensitive to?
The rods (themselves) are sensitive to light The cones are sensitive to colour
Which blood chemical is light sensitive?
The blood chemical constituant that is light sensitive is Bilirubin..
If photo sensitive is for light what is the term for heat sensitive?
thermal.
What is the light sensitive surface that converts light into neural impulses called?
The light sensitive surface that converts light into neural impulse is called the retina
