nadezda [96]

Superscript o subscript negative 1 e.

Explanation:

The nuclear reactions is of 2 types, one is nuclear fusion and the other one is nuclear fission.

Nuclear fusion is nothing but the combining of 2 nuclei with an emission of energy along with an electron, proton or beta particle.

Nuclear fission is the break down of a nucleus into 2 or more nuclei along with an electron, proton or beta particle.

And the reaction is,

₅₆B¹²⁴  ₅₅C¹²⁴ +  ₋₁e⁰

So the blank was filled by means of a beta particle.

There are 4.78 g of dry LICIO4 and
astraxan [27]

Answer:

The number of moles of H₂O is 0.135 mol.

The number of moles of LiClO₄ is 0.0449 mol.

Explanation:

Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.

The number of moles of a substance is calculated by:

\frac{mass of substance}{molecular weight of  substance}

To find the number of moles of H₂O:

Mass of H₂O in the sample = 2.43g

The molecular weight of H₂O = 18.02g

Number of moles = \frac{2.43}{18.02} = 0.135 mol.

To find the number of moles of LiClO₄:

Mass of LiClO₄ given = 4.78g

The molecular weight of LiClO₄ = 106.39g

Number of moles = \frac{4.78}{106.39} = 0.0449 mol.
