As what we see in the chemical reaction that is given, we can conclude that the Lithium must be the reducing agent since it is the one that is oxidised. In addition to that, a redox reaction or simply known as the oxidation-reduction reaction usually operates when electrons get transferred between species.

Which locations are likely to have subatomic particles with the least mass?
rusak2 [61]

Answer:

2 and 3 because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4. The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus. The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.

As the energy level decreases, the size of the orbital:
hoa [83]

Answer:

B or C

Explanation:

When an atom absorbs the right amount of energy, an electron moves from its original orbital to a higher-energy orbital that has a vacancy. Similarly, when an atom emits energy, the electron drops to a lower-energy orbital that has a vacancy.

This is all I could find

Rom4ik [11]

Answer: Melting point of the naphthalene is 80^oC.

Explanation:

Melting point of a substance is temperature at which given solid changes its state from solid to liquid. It is also referred as freezing point of the substance.

Freezing point of substance is a temperature at which given substance changes its state from liquid to solid.

Here, the solid piece of naphthalene is heated and remains at 80°C until it is completely melted.

MrRissso [65]

The question is incomplete, complete question is :

The frequency factors for these two reactions are very close to each other in value. Assuming that they are the same, compute the ratio of the reaction rate constants for these two reactions at 25°C.

\frac{K_1}{K_2}=?

Activation energy of the reaction 1 ,Ea_1 = 14.0 kJ/mol

Activation energy of the reaction 2,Ea_1  = 11.9 kJ/mol

Answer:

0.4284 is the ratio of the rate constants.

Explanation:

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

The expression used with catalyst and without catalyst is,

\frac{K_2}{K_1}=\frac{A\times e^{\frac{-Ea_2}{RT}}}{A\times e^{\frac{-Ea_1}{RT}}}

\frac{K_2}{K_1}=e^{\frac{Ea_1-Ea_2}{RT}}

where,

K_2 = rate constant reaction -1

K_1 = rate constant reaction -2

Activation energy of the reaction 1 ,Ea_1 = 14.0 kJ/mol = 14,000 J

Activation energy of the reaction 2,Ea_1  = 11.9 kJ/mol = 11,900 J

R = gas constant = 8.314 J/ mol K

T = temperature = 25^oC=273+25=298 K

Now put all the given values in this formula, we get

\frac{K_1}{K_2}=e^{\frac{11,900- 14,000Jl}{8.314 J/mol K\times 298 K}}=2.3340

0.4284 is the ratio of the rate constants.
