Answer:
The net ionic equation is
H₃O⁺+NH₃ ↔ NH₄⁺+H₂O
Explanation:
To write the net ionic equation, we are required to dissociate the into ions all strong acids and strong bases
Hence, nitric acid which is a strong acid is dissociated as follows
HNO₃+H₂O → H₃O⁺ + NO₃⁻
in the above equation, the nitrate ion NO₃⁻, is a spectator ion because it is only present and does not partake in the chemical reaction so it is left out of the net ionic equation equation
Also the it is required to keep together weak bases in the solution therefore for NH₃ which is a weak base we have
NH₃ + H₃O⁺ → NH₄⁺ + H₂O
Hence, the net ionic equation becomes
H₃O⁺ (aq) + NH₃ ↔ NH₄⁺(aq) + H₂O (l)

Answer:
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
Explanation:
Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.
petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.
Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.
gas and oil are used to heat homes.
Answer:
The NaCl concentration will be 0.03 M.
Explanation:
Given data:
Initial volume = V₁ = 56.98 mL (56.98/1000 = 0.05698 L)
Initial concentration = M₁= 0.5894 M
Final volume = V₂= 1.20 L
Final concentration = M₂= ?
Solution:
By diluting the solution volume of solution will increase while number of moles of solute remain the same.
Formula:
Initial concentration × Initial volume = Final concentration × Final volume
M₁V₁ = M₂V₂
M₂ = M₁V₁ / V₂
M₂ = 0.5894 M × 0.05698 L / 1.20 L
M₂ = 0.0336 M /1.20
M₂ = 0.03 M
