Lithium nitride reacts with water to produce ammonia and lithium hydroxide according to the equation
li₃n(s)+3h₂o(l)⟶nh₃(g)+3lioh(aq)
heavy water is water with the isotope deuterium in place of ordinary hydrogen, and its formula is d₂o.
the same reaction can be used to produce heavy ammonia, nd₃(g), according to the equation
li₃n(s)+3d₂o(l)⟶nd₃(g)+3liod(aq)
calculate how many grams of heavy water are required to produce 160.0 mg nd₃(g). the mass of deuterium, d, is 2.014 g/mol.

0.48 g D2O

Explanation:

Using the balanced equation we can calculate the mol and grams of heavy water required to produce the 160 mg of ND3 as follows:

Li3N (s) + 3 D2O (l) ND3 (g)  + 3 LiOD (aq)

gD2O = ?

MW ND3 = 20.04 g/mol

160 mg ND3 = 0.160 g ND3 = 0.160g /20.04g /mol =  0.08 mol ND3

1 mol ND3 needs  3 mol D2O to be produced, then

0.08 mol ND3  x 3 mol D2O/1 mol ND3 = 0.024 mol D2O

Then multiplying this number of moles by the molecular weight of D2O ( 20.028 g D2O/mol ) we will get the

0.024 mol D2O  x 20.028 g D2O/ mol = 0.48 g D2O

43.452

step-by-step explanation:

284 times .153 = 43.452

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
