CO2: 12.0107 + 15.9994(2) = 44
NH3: 14.0067 + 1 (3) = 17
1.55 (17/44) = .599g
Answer: Scientific Theory
Explanation:
A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. People commonly use the word theory to describe a guess about how or why something happens.
Answer:
The yield of hydrogen decreases
Explanation:
The Haber process is exothermic. The equation of the Haber process is;
N2(g) + 3H2(g) --------> 2NH3(g) ΔH = -ve
Now, if we maintain a constant temperature, the number of volumes will affect the yield of products as follows;
The higher the pressure the lesser yield of hydrogen because the increase in pressure shifts the equilibrium position towards the right hand side.
Answer:
8 Silicon atom are present in unit cell.
16 oxygen atoms are present unit cell.
Explanation:
Number of atoms in unit cell = Z =?
Density of silica = tex]2.32 g/cm^3[/tex]
Edge length of cubic unit cell = a = 0.700 nm = 
Molar mass of Silica = 
Formula used :
where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.
1 silicon is 2 oxygen atoms. then 8 silicon atoms will be 16 oxygen atoms.
