Li(s)+n2(g)→li3n(s) express your answer as a balanced chemical equation. identify all of the phases in your answer.
elixir [45]
  equation  is   balanced  when  the  number  of  molecules     are  the  equal  in  both  reacting  side  and  the  product side.
Li(s)  +  n2(g) ---> Li3n(s)
From   the  equation  above  the  reaction  is not  balanced  since    the  molecules  are  not  equal  in  both  reacting  side  and  the  product   side.

The reaction  is  balanced   by  adding   6  in  front  of  Li  and  2  infront  of  Li3n
  that  is
 6Li(s)  + n2(g)----->  2Li3n(s)

What type of reaction is shown by this equation?
Romashka-Z-Leto [24]
This is an acid base reaction which is basically a double displacement reaction. However, since carbonic acid is produced, it rapidly decomposes to carbon dioxide and water.

Involves combining of nuclei:
bogdanovich [222]

Explanation:

Involves combining of nuclei:  Nuclear fusion

Nuclear fusion is a radioactive reaction  in which small atomic nuclei combines into larger ones with the release of a large amount of energy. The energy released is used to furnish a series of chain reactions.

Produces dangerous radioactive waste:  Nuclear fission

Nuclear fission is used in powering most nuclear power plants. The products of these reactions are radioactive in nature. They are very dangerous to human health and the environment at large.

Have high activation energies:  Nuclear fusion

The activation energy is the energy barrier that must be overcome before a reaction starts. Nuclear fusion reactions require very high amount of energy input to overcome the activation needed to start the reaction.

Releases large amounts of energy:  Nuclear reactions

Both nuclear fusion and fission releases large amount of energy.

Occurs in the stars:  Nuclear fusion

Nuclear fusion occurs in stars and they involve the combination of atomic nuclei to form larger ones.

Drives chemical plants: Nuclear fission

Chemical plants uses electricity and nuclear power plants can produce electricity through nuclear fission.

The lightest particle among the following is :
Triss [41]

The question is incomplete, the complete question is;

The lightest particle among the following is:

• Electron •Proton • Neutron • Alpha​

Answer:

Electron

Explanation:

There three basic subatomic particles are electrons, protons and neutrons. Both protons and neutrons are found in the nuclear and both contribute towards the mass of the atom. The alpha particle has the same mass as the helium nucleus.

However, the electrons are found in orbiit and have a negligible mass compared to the mass of the protons and neutrons. The mass of the electron is about 9.11 × 10^-31 Kg. This makes it the lightest of all the particles listed among the options.

Two solutions are created by mixing one solution containing lithium nitrate with one containing sodium phosphate.
babunello [35]

Answer:

Solution A that will form a precipitate with Ksp = 2.3 x 10−4

Explanation:

                                  Li₃PO₄ ⇄ 3 Li⁺(aq) + PO₄³⁻(aq)

                                                     3S               S

Where S = Solubility(mole/lit) and Ksp = Solubility product

⇒ Ksp = (3S)³ x (S)

⇒ 27S⁴ = 2.3x10−4

⇒ S = 0.05 mol/lit

Concentration of Li₃PO₄ precipitate = 0.05

<u>Solution A </u>

0.500 lit of a 0.3 molar LiNO₃ contains 0.5 x 0.3 = 0.15 mole

0.4 lit of a 0.2 molar Na₃PO₄ contains = 3 x 0.4 x 0.2 = 0.24 mole

                                     3 LiNO₃ + Na₃PO₄ → 3 NaNO₃ + Li₃PO₄

(Mole/Stoichiometry)    \frac{0.15}{3}                \frac{0.24}{1}

                                   = 0.05            = 0.24

Since from (Mole/Stoichiometry) ratio we can conclude that LiNO₃ is limiting reagent.

So concentration of Li₃PO₄ is equal to 0.05.
