Answer:
Option D: Fluorine
Explanation:
From the periodic table, Nickel and Sodium are metals. Which means that they are good conductors of electricity.
While silicon is a metalloid. A metalloid has properties of both metals and nonmetals. Thus, it has tendencies to conduct electricity.
Fluorine is a non - metal which means that it doesn't conduct electricity.
Thus, the most likely that is not a good conductor is Fluorine.
635ml will yield 1m of hcl
xml will yield 10m of hcl
that means 6250ml will yield 10m of hcl
Multiply first the mass given in kilograms by 1000 in order to convert it to grams.
(0.23 kg) (1000 g / 1kg) = 230 g
Then, divide the mass in gram by the molar mass of SO2
molar mass of SO2 = 64.044 g/mol
Solving for the number of moles,
(230 g)(1 mol/64.044g) = 3.59 moles
Thus, there are approximately 3.59 moles of SO2 present in 0.23 kg of SO2.
