Answer:
A catalytic converter is a device used to reduce the emissions from an internal combustion engine (used in most modern day automobiles and vehicles). Not enough oxygen is available to oxidize the carbon fuel in these engines completely into carbon dioxide and water; thus toxic by-products are produced. Catalytic converters are used in exhaust systems to provide a site for the oxidation and reduction of toxic by-products (like nitrogen oxides, carbon monoxide, and hydrocarbons) of fuel into less hazardous substances such as carbon dioxide, water vapor, and nitrogen gas.
Answer:
3) Neither created nor destroyed. Only converted.
Explanation:
If you look at the periodic table, Krypton has an atomic number of 36. Krypton is one of the noble gases. They are a group of elements that are very stable because they obey the Octet Rule. As a result, other elements try to conform the electronic configurations of the nearest noble gases to them. They either give or take electrons in their valence shell.
The three atoms that have 36 electrons are: Kr (Krypton), Br⁻ (Bromide), and Rb⁺(Rubidium ion).
