Answer:
<em>It is impossible to predict when an individual radioactive atom will decay. ... Rather, the half-life describes the average amount of time it takes for a large group of amounts to reach the point where half of the atoms have decayed.</em>
Explanation:
Some laces get warm and some get cold
N2 + 3H2 --> 2NH3
When 100g of N2 , no of moles of N2= 100/(28)=3.57 mol
no. of moles of h2 = 6/(2)=3mol
Therefore h2 is limiting reagent.
no. of moles of ammonia= 3/3*2=2moles
mass of ammonia produced= 2 mol * (14+3)= 34g
A, I believe it is 810liters of oxygen! Please correct me if im wrong
Answer:It is necessary to use Kelvin for the temperature and it is conventional to use the SI unit of liters for the volume.
Explanation:
However, pressure is commonly measured in one of three units: kPa, atm, or mmHg. Therefore, can have three different values.
