equation is balanced when the number of molecules are the equal in both reacting side and the product side.
Li(s) + n2(g) ---> Li3n(s)
From the equation above the reaction is not balanced since the molecules are not equal in both reacting side and the product side.
The reaction is balanced by adding 6 in front of Li and 2 infront of Li3n
that is
6Li(s) + n2(g)-----> 2Li3n(s)
We have that for the Question, it can be said that the mass of Ammonia is
Mass_a=3.162grams
From the question we are told
<em>Ammonia </em>gas has a <u>molar</u> mass of approximately 17 <u>grams </u>per mole. At 290k and 1.2 atm, a sample of <em>ammonia </em>has a volume of 3.7 L. In <em>three </em>to five sentences, explain how you can find the mass of the <em>ammonia</em>. Then, given R= 0.0821L.atm/mol.k, calculate the mass.
Generally the equation for the is mathematically given as
Now the mass of ammonia is
Hence the mass of Ammonia is
Mass_a=3.162grams

Answer:
The correct answer is 4,556.2 J
Explanation:
The amount of heat is calculated with the following equation:
Heat= m x Cs x ΔT
Given:
m= 100.0 g (mass)
Cs= 4.18 J/g.ºC (specific heat)
ΔT= 10.9ºC (change in temperature)
We introduce the data in the equation and calculate the heat:
Heat = 100.0 g x 4.18 J/ºC.g x 10.9ºC = 4,556.2 J
Therefore, the amount of heat absorbed by the water (gained by the solution) is 4,556.2 J
This is because the animals with the favorable traits would survive. Therefore they will be the only ones left because they were able to adapt to the environment. And when they breed, the offspring will gain those favorable and the less favorable traits will continue to not be used which is why they “fade away” overtime.
