Predict the missing particle or nuclide.
Advocard [28]

Answer:

beta minus emission

Explanation:

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminum is used to block the beta radiation

²³⁹₉₃Np→ ²³⁹₉₄Pu + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.

How many grams of h2 are needed to produce 10.78 g of nh3?
balu736 [363]
Ammonia is formed by a reaction between hydrogen and nitrogen as shown by the equation below.
N2(g) + 3H2(g) = 2NH3(g)
1 mole of ammonia contains 17 g
Therefore 10.78 g of ammonia are equivalent to 10.78/17 = 0.6341 moles
The mole ratio of hydrogen to ammonia is 3 : 2
Therefore, moles of hydrogen used will be  0.6341 × 3/2 = 0.9512 moles
1 mole of hydrogen is equivalent to 2 g
Thus, the mas of hydrogen will be 0.9512 moles × 2 = 1.9023 g

Choose the molecule with the strongest internal bond, (intra-, not intermolecular bond) ​
Verdich [7]

Answer:

A

Explanation:

The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.

  • Fluorine is the most electronegative element in nature.
  • When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond.
  • This tendency and ability makes the shared electrons closer the fluorine in the bond.
  • The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.
