Radon is the heaviest gas on Earth with a density of about 9.73 g/L. This is very high actually.
For more informations, radon is mostly used in radioactivity and cancer therapy.
Hope this Helps :)
if you know what kind of chemical a reactant is, it can help you to quickly distinguish the chemical reaction.
Ex:
HCl + KOH <---> KCl + H2O
We can look at the reactants and identify that this reaction is an acid-base reaction because HCl is an acid (it gave a proton) and KOH is a base (it accepted the proton)
For the first question, i think the correct answer is the third option. When a gas is formed, it is <span>the most conclusive in determining whether a chemical reaction has taken place given that none of your reactants is a gas.
For the second question, the statement is true.
For the third question, the correct answer is the last option.</span>
2.67×g of form when 6. 00 moles of bromine react completely.
As per the chemical equation 2 moles of Aluminum react with 3 moles of Bromine to generate 2 moles of Aluminum Bromide
Molecular Weight of Al= 27 g/mol
Molecular Weight of Bromine= 159.8 g/mol
Molecular Weight of Aluminum Bromide= 266.7 g/mol
So,
Moles of Br = 6 moles
Moles of Al = = 4moles
similarly,
moles of = = 1mole
Moles of =
1 mole =
weight = 2.67×g
