Answer : The correct answer is : Difference in edges , length and angles .
Crystal system shows large varieties of forms . These forms differs due to difference in length , angles and edges . On the basis of their difference in edge length and angles they can be of following types :
1) Cubic
2) Tetragonal
3) Hexagonal
4) Orthorhombic
5)Rhombohedral
6) Monoclinic
7) Triclinic
Red phosphorus and white phosphorus are solid is a physical property
First, find length of AB, using coordinates of the points A and B.
A(1,4) and B(4,8)
|AB|=√((y2-y1)² +(x2-x1)²) =√((8-4)²+(4-1)²)=√(16+9)=√25=5
When dilating with scale factor 4,
the length of |A'B'|=4*|AB|=4*5=20
Answer:
The answer to your question is a) N₂ b) 3.04 g of NH₃
Explanation:
Data
mass of H₂ = 2.5 g
mass of N₂ = 2.5 g
molar mass H₂ = 2.02 g
molar mass of N₂ = 28.02 g
molar mass of NH₃ = 17.04 g
Balanced chemical reaction
3H₂ + 1 N₂ ⇒ 2NH₃
A)
Calculate the theoretical yield 3H₂ / N₂ = 3(2.02) / 28.02 = 0.22
Calculate the experimental yield H₂/N₂ = 2.5/2.5 = 1
Conclusion
The limiting reactant is N₂ (nitrogen) because the experimental proportion was higher than the theoretical proportion.
B)
28.02 g of N₂ -------------------- (2 x 17.04) g of NH₃
2.5 g of N₂ -------------------- x
x = (2.5 x 2 x 17.04) / 28.02
x = 85.2 / 28.02
x = 3.04 g of NH₃
