Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it: solids becomes liquid, and liquids becomes gaseous. If even more energy is supplied to a gas, it is ionized and goes into the energy-rich plasma state, the fourth state of matter.ore than 99% of the visible matter in the universe is in the plasma state.
 
        
             
        
        
        
Molarity is defined as the ratio of number of moles to the volume of solution in litres.
The mathematical expression is given as:

Here, molarity is equal to 1.43 M and volume is equal to 785 mL.
Convert mL into L
As, 1 mL = 0.001 L
Thus, volume =  = 0.785 L
 = 0.785 L
Rearrange the formula of molarity in terms of number of moles:

n = 
= 1.12255 mole
Now,  Number of moles  = 
Molar mass of potassium hydroxide  = 56.10 g/mol
 1.12255 mole  = 
mass in g =  
 
= 62.97 g
Hence, mass of  = 62.97 g
 = 62.97 g

Answer:
a. 0.5 mol
b. 1.5 mol
c. 0.67
Explanation:
Fe3+ + SCN- -----> [FeSCN]2+
a. The ratio of the product to Fe3+ is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of Fe3+ was used. Leaving 0.5 mol remaining at equilibrium
b. The ratio of the product to SCN= is 1:1. Meaning that if 0.5 mol of product was produced up then 0.5 mol of SCN- was used. Leaving 1.5 mol remaining at equilibrium
c. KC =  0.5/(0.5*1.5) =  0.67
