A foliated rock forms when the minerals are realigned due to the presence of high temperature and pressure. The minerals align in such a way that the axes are directed to where the pressure was applied.
Answer:
Volume of ammonia produced = 398.7 dm³
Explanation:
Given data:
Volume of N₂ = 200 dm³
Pressure and temperature = standard
Volume of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Number of moles of N₂:
PV = nRT
1 atm× 200 L = n× 0.0821 atm.L/mol.K × 273 K
n = 200 atm.L /22.41 atm.L/mol
n = 8.9 mol
Now we will compare the moles of ammonia and nitrogen.
N₂ : NH₃
1 : 2
8.9 : 2/1×8.9 = 17.8 mol
Volume of ammonia:
1 mole of any gas occupy 22.4 dm³ volume
17.8 mol ×22.4 dm³/1 mol = 398.7 dm³
In a titration experiment, 31. 4 ml of 1. 120 M HCOOH is neutralized by 16. 3 ml of 
. So, the concentration of the solution is 23.16 M
Calculation,
The formula for the dilution of a solution is given as:
= 
Where M is molarity and V is the volume of the solution in liters ( L ).
Given data,
= 120 M
=31. 4 ml
= ?
= 16. 3 ml
120 M ×31. 4 ml = × 16. 3 ml
= 120 M ×31. 4 ml / 16. 3 ml =23.16 M
In a titration experiment, the concentration of the solution is 23.16 M

Answer: The density of a liquid determines whether it will float on or sink in another liquid. A liquid will float if it is less dense than the liquid it is placed in. A liquid will sink if it is more dense than the liquid it is placed in.
