Answer: It will lead to form a white colored product 
.
Explanation: The reaction of iodine and zinc involves the direct reaction between a metal and a non-metal leading to the synthesis of a metal salt.
During this reaction, heat is released (exothermic reaction) while forming Zinc Iodide() which can be easily obtained by evaporating the solvent.
By looking at the stoichiometric coefficients of reactants and products, we observe that whole of the iodine has reacted with zinc.
Pb(BrO3)2 is an ionic compound, Pb is a metal, (BrO3) is a non-metal part.
Pb(BrO3)2 is a salt, all salts are ionic compounds.

Answer:
93.5 moles N₂
Explanation:
To find the moles, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = constant (0.0821 atm*L/mol*K)
-----> T = temperature (K)
You can plug the given values into the equation and simplify to find moles. The final answer should have 3 sig figs to match the lowest number of sig figs among the given values.
P = 95.0 atm R = 0.0821 atm*L/mol*K
V = 224 L T = 2773 K
n = ?
PV = nRT
(95.0 atm)(224 L) = n(0.0821 atm*L/mol*K)(2773 K)
21280 = n(227.6633)
93.5 = n
