Answer:
The answer to your question is 1.2 moles
Explanation:
Reaction
N₂(g) + 3H₂ (g) ⇒ 2NH₃
Check if the reaction is balanced
Reactants Elements Products
2 N 2
6 H 6
As the number of reactants is equal to the number of products, this reaction is balanced.
Now, calculate the moles of ammonia produced using proportions
1 mol of nitrogen -------------- 2 moles of ammonia
0.6 mol of nitrogen ----------- x
x = (0.6 x 2) / 1
x = 1.2 / 1
x = 1.2 moles of ammonia are formed
It is nitrogen and oxygen.

Good Luck Studying :)</span>
1.53 mole of n2o2.
now just multiply 1.53 by avogadro's number.
1.53 x 6.02 x 10^23 = 9.21 x 10^23
that is your answer in scientific notation
Answer:
Moles = Mass / Mr
Moles = Concentration x Volume
Explanation:
Moles can be worked out in several ways depending on the information you are given. Some of the equations containing moles are:
Moles = Mass / Mr
Moles = Concentration x Volume
Answer:
151.1J
Explanation:
Given parameters:
Mass of iron = 6.21g
Initial temperature of iron = 25°C
Final temperature of iron = 79.8°C
Unknown:
Amount of heat = ?
Solution:
The amount of heat require to cause this temperature can be determined using the expression below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
Specific heat capacity of iron 0.444J/g°C
Insert the parameters and solve;
H = 6.21 x 0.444 x (79.8 - 25)
H = 151.1J
