Answer:
The number of moles = 0.66 mole
Explanation:
Given as :
The volume of container (V) = 10.0 liter
The temperature (T)= 373 kelvin
The pressure of gas (P) = 203 k pa = 2.0034 atm
Let the number of mole = n
Now from at ideal gas law
PV = nRT
Where R = 0.08206 L atm per mol per kelvin
SO, (2.0034 × 10 ) = n × 0.08206 × 373
Or, (20.034 ) = n × 30.608
∴ n =
Or n = 0.654
Hence the number of mole = 0.66 mole Answer
Answer:
He started factories and mills. He created World's first water- powered mill at Cromford, where he employed more than 200 people. This was just the beginning of the many factories which he would later set up. Because of this, Arkwright was known as the father of the modern industrial factory system........Hope you got it
Amphiprotic compounds are able to both donate and accept a proton.
Amphiprotic compounds contain a hydrogen atom and lone pair of valence electron.
For example, HSO₃⁻ (hydrogen sulfate ion) is an amphiprotic compound.
Balanced chemical equation for reaction when HSO₃⁻ donate protons to water:
HSO₃⁻(aq) + H₂O(l) ⇄ SO₄²⁻(aq) + H₃O⁺(aq).
Ka = [SO₄²⁻] · [H₃O⁺] / [HSO₃⁻]
Balanced chemical equation for reaction when HSO₃⁻ accepts protons from water:
HSO₃⁻(aq) + H₂O(l) ⇄ H₂SO₄(aq) + OH⁻(aq).
Kb = [H₂SO₄] · [OH⁻] / [HSO₃⁻]
Water (H₂O), amino acids, hydrogen carbonate ions (HCO₃⁻) are examples of amphiprotic species.
Another example, water is an amphiprotic substance:
H₂O + HCl → H₃O⁺ + Cl⁻
H₂O + NH₃ → NH₄⁺ + OH⁻

Q = mCΔT
Q is heat in Joules, m is mass, C is the specific heat of water, delta T is the change in temperature
Q = (35g)(4.18)(35 degrees) = 5121 Joules or 5.12 kJ required
The direction of spontaneous change is the direction in which total<span> entropy increases. Total entropy change, also called the entropy change of the universe, is the sum of the entropy change of a system </span>and<span> of its surroundings</span>
