In a lab, 20.0 g of ammonia (NH3) are reacted with 20.0 g of hydrogen chloride (HCl) to produce solid ammonium chloride. NH3(g) + HCl(9) ► NH4Cl(s) What mass of ammonium chloride is produced? g NH4Cl Your answer should have 3 significant digits. Do not include units In your answer. Enter the answer​

i think   the answer is c hope i'm right

have a great day because if you dont you and i will be sad

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
