Chemistry
1 answer:
NARA [144]3 years ago
7 0

Should be B. It is talking about reducing thermal energy from transferring, so insulation is the only thing that helps. High efficiency appliances saves you electricity, and C is talking about renewable energy.

Is there an N−Cl bond in solid ammonium chloride?
Tems11 [23]
When ammonia is reacted with HCl it abstracts proton from acid and forms Ammonium Ion and Chloride Ion.

                              NH₃  +  HCl   →   ⁺NH₄  + Cl⁻ (simply Written NH₄Cl)
Structure,
              The structure of Ammonium Chloride is among those structures which contains all three types of bonding's, i.e.
                                  
                                                Ionic Bond

                                                Covalent Bond

                                                Coordinate Covalent Bond

Three Hydrogen atoms previously bonded with Nitrogen are covalent in nature. The new incoming proton from HCl forms co-ordinate covalent bond with Nitrogen and Chloride Ion containing negative charge make Ionic Bond with the positive Ammonium Ion. In question, if the line between Nitrogen and Chlorine atom is assumed covalent then it is incorrect. Structure is shown below,

5. A sample of gas occupies 1.55 L at 27 degrees Celsius and 1.00 atm pressure. What will the volume be if the pressure is incre
Sergio039 [100]

Answer:

The volume will be 0.031 L

Explanation:

Since temperature is constant, Boyle's law is applied in this case.

Boyle's law States that at constant temperature, the volume of a given mass of a gas is inversely proportional to it's pressure.

From this statement it was deduced that P1V1 = P2V2

From the question, P1 = 1atm, V1 = 1.55L, P2 = 50 atm and V2 is to be calculated.

V2 = P1V1/P2

= 1×1.55÷50

=0.031 L
