Answer:
The correct answer is
e. NH3(aq) + H+(aq) --> NH4+(aq)
Explanation:
To solve this, we write out the indidual ionization reation for aqueous ammonia and nitric acid thus
For aqueous ammonia we have
NH₃(aq) + H₂O(l) ↔ NH₄⁺(aq) + OH⁻(aq)
Aqueous ammonia is a weak base and therefore undergoes partial ionization hence the reversible reaction sign
As the level of ionization will not be more than 5% OH⁻ cannot represebt the weak base
For nitric acid we have
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
a strong acid like nitric acid undergoes conplete ionization in the solution
The total equation is NH₃(aq) + HNO₃(aq) → NH₄NO₃(aq)
The sum of the ionic equation is
NH₃(aq) + H⁺(aq) + NO₃⁻(aq) → NH₄⁺(aq) + NO₃⁻(aq)
The ionic equation is
NH₃(aq) + H⁺(aq) → NH₄⁺(aq)
Answer:When making observations during an experiment, Descriptions of any changes in the system following an action and Descriptions of any non-changes in the system following an action a list of possible errors must be included. The correct option is C and D.
Explanation: During a scientific experiment procedures, observation is usually carried out to take into consideration an active information from the natural source. Data can be collected by the observer:
- quantitatively ( by counting and measuring data when numerical values are attached.
- qualitatively ( when the presence or absence of a property is noted). Hence, option C and D are correct.
