Answer:
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
Explanation:
Assuming Pressure is constant.
where T1 and T2 are temperature in Kelvin
Substituting the give values we get-
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
The [H₃0⁺] of the solution : 1.778 x 10⁻¹² M
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH of solution = 11.75
the [H₃0⁺] of the solution :
Answer:
mass number!
Explanation:
remember your atomic number is the amount of protons in an atom while your mass number is the total number of neutrons and protons in a atom
This reaction is decomposition. It is the breakdown of a compound into simpler and smaller elements.
Answer:
Ans. is 20.80 kJ/mol,
Explanation:
the vapor pressure of a liquid at temperature range of 200K to 260K was found to fit the expression ln(p/torr)=16.255 - 2501.8/(T/K).
