Answer:
Explanation:
Given: Entropy of surrounding: ΔSsurr = ?
Temperature: T= 355 K
The change in enthalpy of reaction: ΔH = -114 kJ
Pressure: P = constant
As we know, ΔH = -114 kJ ⇒ negative
Therefore, the given reaction is an exothermic reaction
Therefore, Entropy of surrounding at <em>constant pressure</em> is given by,
<u><em>In the given reaction:</em></u>
2NO(g) + O₂(g) → 2NO₂(g)
As, the number of moles of gaseous products is less than the number of moles of gaseous reactants.
As we know, <em>for a spontaneous process, that the total entropy should be positive.</em>
<u>Therefore, at the given temperature,</u>
- if then the given reaction is spontaneous
- if then the given reaction is non-spontaneous
The pH of a solution depicts the alkalinity or the acidity of the components of the solution and is given as a negative log function of hydrogen ions.
The pH of the solution is:
2
The pH can be estimated as:
- Ionic equation of reaction is written as:
- The mole ratio between HCl and = 1 : 1
- Concentration of = 0.01 M
Therefore, 2 is the pH of the solution.

Answer:
1.01atm
Explanation:
760mmHg = 1atm
765mm Hg = 765/760 = 1.01atm
Therefore, the barometer reading in atmosphere is 1.01atm
Answer:
A. It has one carbon atom
D. It has two oxygen atoms
E. It is a chemical compound
