Answer:

metallic bonding

Explanation:

Metallic bonding is bonding where electrons exist as "sea of electrons" meaning they can go anywhere in the structure and are not localized in specific place like covalent bonds are sometimes.

NISA [10]

Answer:

D.

Explanation:

D. A strong force exists between the particles in a nucleus, and this force is usually stronger than the electric forces that would pull them apart.

A strong force acts only on very short distances, and stronger than electric forces when particles are very close.

Cyclopropane, C3H6, is used as a general anesthetic. If a sample of cyclopropane stored in a 2.36-L container at 10.0 atm and 25
alekssr [168]

Explanation:

The given data is as follows.

     V_{1} = 2.36 L,    T_{1} = 25^{o}C = (25 + 273) K = 298 K,

      P_{1} = 10.0 atm,   V_{2} = 7.79 L,

       T_{2} = ?,       P_{2} = 5.56 atm  

And, according to ideal gas equation,  

               \frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}

Hence, putting the given values into the above formula to calculate the value of final temperature as follows.          

 \frac{10.0 atm \times 2.36 L}{298 K} = \frac{5.56 atm \times 7.79 L}{T_{2}}

            T_{2} = \frac{43.3124}{0.0792} K

                     = 546.87 K

Thus, we can conclude that the final temperature is 546.87 K.

When NAD becomes NADH, it is being reduced and gaining chemical energy.

Nicotinamide adenine dinucleotide (NAD), a coenzyme, can exist in two forms, NAD⁺ (oxidized) and NADH (reduced form).

Electrons and protons released in catabolism reactions are attached to NAD⁺. The conversion of NAD⁺ to NADH is important reaction for production of ATP during the cellular respiration.

Reduction is lowering oxidation number because element, ion or compound gain electrons.

Chemical equation for reaction of reduction of NAD⁺ (see picture below):

NAD⁺ + 2e⁻ + H⁺ → NADH

Nicotinamide adenine dinucleotide (NAD) is made of two nucleosides joined by pyrophosphate.
