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:
3- gamma radiation
Explanation:
Hello,
In the above question, 4 of the options are related to polymerization which are
1. Synthetic polymer
2. Natural polymer
3. Condensation polymerization
4. Addition polymerization.
The first two options are types of polymer that exists while the last two are polymerization techniques.
The odd option here which is "gamma radiation" is a particle which is emitted from radioactive substances during decay. It has no mass and no charge but it is highly penetrating and dangerous to human health.
However,
Synthetic polymers are also known as man made polymers and they exist around us because they're present in materials which we use everyday. An example is polyethylene, nylon-6,6 etc
Natural polymers are compounds which are polymeric in nature (compounds catenating to form a complex molecule). Natrual occurring polymers can be found in proteins and some lipids.

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the absorbed heat by considering this is a process involving sensible heat associated to the vaporization of water, which is isothermic and isobaric; and thus, the heat of vaporization of water, with a value of about 2259.36 J/g, is used as shown below:
Thus, we plug in the mass and the aforementioned heat of vaporization of water to obtain the following:
