Ozone depleting chemicals are most likely belong to <u>halogen </u>group on the periodic table.
<h3>Ozone depleting chemicals are most likely to belong to which group on the periodic table?</h3>
Ozone depleting chemicals are the halogen group on the periodic table. Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromo-fluorocarbons and methyl chloroform. Fluorine, chlorine, bromine, iodine, astatine and tennessine are the elements of halogen group elements. These elements greatly affected the ozone layer.
So we can conclude that Ozone depleting chemicals are most likely belong to halogen group on the periodic table.

Answer:
You will generate 0.124 moles of aluminum when you react 0.372 moles of potassium
Explanation:
Determine the reaction:
3K + AlBr₃ → Al + 3KBr
Ratio is 3:1
3 moles of K can produce 1 mol of Al
So, 0.372 moles of K, may produce (0.372 .1) /3 = 0.124 moles of Al
Answer:
Yes the given equation is balanced.
Explanation:
Chemical equation:
Fe + O₂ → Fe₂O₃
Balanced chemical equation:
4Fe + 3O₂ → 2Fe₂O₃
There are four iron and six oxygen atoms on both side of equation thus the given equation is balanced.
The given reaction also follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
This reaction is synthesis reaction:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
the false statements are a, and e (not sure about e but think a is false)
Answer:
Isotopes are atoms with the same number of protons, but different numbers of neutrons.
Explanation:
Ex.
Ne 20/10
Ne 21/10
Ne 22/10
*the number of protons in an atom must stay the same or the element itself will change drastically
