Answer: The correct option is B.
Explanation: Ammonia which is used as a household cleaner, has an IUPAC name as nitrogen trioxide.
Symbol for Nitrogen = N
Symbol for Hydrogen = H
In ammonia, Number of nitrogen atoms are 3 and number of hydrogen atoms are 3.
The formula for ammonia becomes 
Therefore, the correct option is B.
Answer:
Potential energy
Explanation:
Potential energy is the energy possed by an object at rest. It is otherwise referred to as the stored energy due position.
Answer:
The answer to your questions is Cm = 25.5 J/mol°C
Explanation:
Data
Heat capacity = 0.390 J/g°C
Molar heat capacity = ?
Process
1.- Look for the atomic number of Zinc
Z = 65.4 g/mol
2.- Convert heat capacity to molar heat capacity
(0.390 J/g°C)(65.4 g/mol)
- Simplify and result
Cm = 25.5 J/mol°C
Answer:
The equilibrium is shifted to the formation of OH⁻.
Explanation:
AH + OH⁻ ⇄ A⁻ + H₂O
At the equivalence point, the acid AH has entirely been converted to A⁻, which is its conjugated base. This causes the equilibrium to shif to consume the excess of A⁻, which leads to production of OH⁻. This is why, at the equivalence point, the pH is larger than 7.
