The decomposition of 86.5 g ammonium nitrate yields how many liters of dinitrogen monoxide at 1.28 atm and 328k
nh4no3-> n2o+2h2o

First, we calculate the moles of ammonium nitrate:
Moles = mass / molecular mass
Moles = 86.5 / 80
Moles = 1.08

From the equation, it is visible that the molar ratio between ammonium nitrate and dinitrogen monoxide is 1 : 1. The moles of dinitrogen monoxide formed will be:
1.08 moles

Next, we may apply the ideal gas law equation to find the volume:
PV = nRT
V = nRT/P
V = (1.08 * 0.082 * 328)/1.28
V = 22.69 liters

22.7 liters of dinitrogen monoxide will be produced

The answer is 3,5g co

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
