The balanced equation for the reaction between NaI and Cl₂
2NaI and Cl₂ --> 2NaCl + I₂
stoichiometry of NaI to I₂ is 2:1
this means that when 2 mol of NaI reacts, it produces 1 mol of I₂
Molar mass of I₂ is 254 g/mol
Number of I₂ moles produced - 48.7 g / 254 g/mol = 0.192 mol
for 1 mol of I₂ to be formed - 2 mol of NaI required
Therefore to form 0.192 mol of I₂ - 2 x 0.192 = 0.384 mol of NaI
Then mass of NaI required - 0.384 mol x 150 g/mol = 57.6 g
120 barrels = 15120 quarts
To convert from barrels to quarts, you just need to multiply the value in barrels by 126 (the conversion factor).
So, 120 barrels = 120 × 126 = 15120 quarts.
id say theres a good plenty!
Answer:
B. Poor conductor.
Explanation:
It cannot be A, as only 1 metal is not solid at room temp.
It cannot be C, as most metals are ductile.
It cannot be D, as most metals are malleable.
This leaves B, which is not true about metals, as a lot are very good conductors.
