The question is incomplete, complete question is :
In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 348 liters per second of dinitrogen are consumed when the reaction is run at 205°C and 0.72 atm. Calculate the rate at which ammonia is being produced.
Answer:
The rate of production of ammonia is 217.08 grams per second.
Explanation:
Volume of dinitrogen used in a second = 348 L
Temperature of the gas = T = 205°C = 205+273 K = 478 K
Pressure of the gas = P = 0.72 atm
Moles of dinitrogen = n
According to reaction, 1 mole of dinitriogen gives 2 mole of ammonia.Then 6.385 moles of dinitrogen will give:
Mass of 12.769 moles of ammonia;
12.769 mol 17 g/mol = 217.08 g
217.08 grams of ammonia is produced per second.So, the rate of production of ammonia is 217.08 grams per second.
Answer:
A = non polar solvent.
Explanation:
Solvent:
Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.
Explanation:
In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.
The solvent dissolve the solute. The dissolution of solute in to solvent always follow the " like dissolve like " rule of chemistry.
If solvent is made up of polar substance then it dissolve the polar solute. If it is non polar then it can dissolve the non polar substances.
Example:
Iodine have covalent iodine-iodine bond which is non polar so iodine would dissolve in ethanol. Ethanol in non polar solvent.
