Neutrons are very important in provide stability for an atom. When atoms are created by fusion, neutrons are included in this process. Because protons don't like each other and repel each other that's where neutrons come in.
Answer:
Partial pressure of ICl at equilibrium is 1.69 atm
Partial pressure of chloride gas at equilibrium is 0.00631 atm.
Partial pressure of iodine gas at equilibrium is 0.00631 atm.
Explanation:
The partial pressure of ICl initially = 1.70 atm
The equilibrium constant of the reaction =
Initially
1.70 atm 0 0
At equilibrium
(1.70-2p) p p
The expression of equilibrium constant is given by :
Solving for p :
p = 0.00631 atm
Partial pressure of ICl at equilibrium = 1.70 atm- 2 0.00631 atm = 1.69 atm
Partial pressure of chloride gas at equilibrium = 0.00631 atm.
Partial pressure of iodine gas at equilibrium = 0.00631 atm.
The molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
CaVa = CbVb
Where;
- Ca = concentration of acid
- Cb = concentration of base
- Va = volume of acid
- Vb = volume of base
60 × 0.0100 = 30 × Cb
0.6 = 30Cb
Cb = 0.6/30
Cb = 0.02M
Therefore, molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.

Answer:
A = l×b
Explanation:
Rectangle is a closed figure with 4 vertices. Each angle of a rectangle is 90 degrees. The opposite sides of a rectangle are equal.
Let l is the length of opposite sides of a rectangle and b is the breadth of the opposite sides of a rectangle.
The area of a rectangle is then given by :
A = l×b
i.e. area of a rectangle is equal to length times breadth.
