Answer: The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Answer:
The percent yield of the reaction is 82.5%
Explanation:
Let's work with moles to get the percent yield.
Mass / Molar mass =
652.5 g / 158.03 g/m = 4.13 moles
If the theoretical yield of the reaction is 5 moles but we only made 4.13 moles, the percent yield will be:
(Produced yield / Theoretical yield) . 100 =
(4.13 / 5) . 100 = 82.5 %
Answer:
0.015 mol AgI
Explanation:
First of all, you have provided an unbalanced equation, so let's balance that:
2AgNO3(aq) + CaI2(aq) --> 2AgI(s) + Ca(NO3)2(aq)
Then let's calculate the moles of AgNO3 using the formula: n = c * V:
c(AgNO3) = 0.300 M (mol/L)
V(AgNO3 - solution) = 50.0 mL = 0.05 L
n(AgNO3) = c (AgNO3) * V(AgNO3) = 0.300 mol/L * 0.05 L = 0.015 mol
Finally, using the coefficients in the equation, we find the moles of AgI:
n(AgNO3) : n(AgI) = 1 : 1
n(AgI) = n(AgNO3) = 0.015 mol
