Volume of solution in liters:
5.00 x 10² mL / 1000 => 0.5 L
number of moles:
mass of solute / molar mass
21.1 / 119.0 => 0.1773 moles
Molarity = number of moles / volume
M = 0.1773 / 0.5
M = 0.355 mol/L

Answer:
I think it would be b. The octet rule states that transition metal group elements tend to react so that they attain a noble gas electron configuration.
Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of 
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So, 
So, for the reaction of 1.57 moles of , 
As, is negative therefore reaction is product favored under standard condition.
A thermocouple is a sensor used to measure temperature. Thermocouples are made with two wires of different metals, joined together at one end to form a junction. ... Naturally, a thermocouple outputs a millivolt signal, therefore, as the resistance changes, the change in voltage can be measured.
