Hydrocarbons in which some or all of the hydrogen atoms are replaced by chlorine and fluorine?
Chlorofluorocarbons (CFCs) are hydrocarbons in which some or all of the hydrogen atoms are replaced by chlorine and fluorine. These chemicals were commonly used in refrigerants, propellants, and solvents but are now known to be harmful to the ozone layer.
Teflon is a polymer of ethylene where all the hydrogens have been replaced by chlorine?
Teflon is a polymer of tetrafluoroethylene, not ethylene. It is a synthetic fluoropolymer in which all the hydrogens in the ethylene backbone have been replaced by fluorine atoms. This substitution makes Teflon highly non-reactive and resistant to heat and chemicals.
Why does 111-trichloroethane is being replaced in favour of a better solvemt?
1,1,1-trichloroethane is being replaced because it is classified as a volatile organic compound (VOC) and poses risks to human health and the environment. It is being substituted with safer solvents that are less harmful and have lower environmental impact. The replacement is part of efforts to reduce emissions of harmful chemicals and promote sustainability.
Which are the chamicals used to make picture tube?
Picture tubes typically consist of different chemicals such as lead oxides, barium compounds, phosphors, and heavy metals like cadmium and mercury. These chemicals help in the production of color and image on the screen by converting electric signals into light. However, due to environmental concerns, newer display technologies have mostly replaced picture tubes.
Can chemicals change by being combined with other chemicals?
Chemicals yes, elements however, no. Elements are themselves chemicals, Burn hydrogen in oxygen and you'll end up with water, another chemical.

What is the fear of chemicals?
Chemophobia - Fear of chemicals or working with chemicals.
What are the chemicals in spray paint?

What kind of energy change takes place in the fuel cell?
A fuel cell (like a battery) converts chemical energy to electrical energy. The main difference being in the fuel cell the energy rich chemicals are continually being resupplied, while in a battery the energy rich chemicals were put in when the battery was initially assembled and cannot readily be replaced or resupplied.
Where does chemicals come from?
Chemicals are natural or artificial.
