Answer: 3.94 atm
Explanation:
Given that,
Initial pressure (P1) = 3.80atm
Initial temperature (T1) = 25°C
since the standard unit of temperature is Kelvin, convert 25°C to Kelvin
(25°C + 273= 298K)
Final pressure P2 = ?
Final temperature T2 = 36°C
(36°C + 273= 309K)
Since pressure and temperature are given while volume is held constant, apply the formula for Pressure's law
P1/T1 = P2/T2
3.80 atm / 298K = P2 / 309K
To get the value of P2, cross multiply
3.80 atm x 309K = P2 x 298K
1174.2 atm•K = 298K•P2
Divide both sides by 298K
1174.2 atm•K/298K = 298K•P2/298K
3.94 atm = P2
Thus, the final pressure is 3.94 atm
Answer:
First ionization step:
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
Second ionization step:
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
Explanation:
Selenic acid is a dyprotic and a strong acid with the formula: H₂SeO₄.
When it reacts to water, it release two protons in two ionizations.
Finally it gives hydronium to the medium.
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Tides are the rise and fall of the oceans. They are caused by the gravity, or pull, of the Moon and Sun. The Moon's gravity is the main force in causing tides. It makes the oceans bulge out toward it. Another bulge occurs on the opposite side, because Earth is being pulled toward the Moon and away from the water. The water on the side farthest away from the Moon is least affected by its gravity.
In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
