Answer:

²³⁸₉₃Np  → Pu₉₄²³⁸ + ⁰₋₁e

Explanation:

²³⁸₉₃Np  → Pu₉₄²³⁸ + ⁰₋₁e

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 aluminium is used to block the beta radiation

⁴₆C → ¹⁴₇N + ⁰₋₁e

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

A chemist has a block of aluminum metal (density is 2.7 g/mL). The block weighs 1.5. What is the volume of the aluminum block?
12345 [234]

Answer:

0.56 mL

Explanation:

Volume = mass ÷ density

Volume = 1.5 ÷ 2.7 g/mL

Volume = 0.5555555556 = 0.56 mL

The volume of the aluminum block is 0.56 mL.

Hope this helps. :)

Question 2
Naddika [18.5K]

Answer:

38.4 atm

Explanation:

Data obtained from the question include:

V1 (initial volume) = 3200 L

P1 (initial pressure) = 3.00 atm

V2 (final volume) = 250.0 L

P2 (final pressure) = ?

Using Boyle's law equation P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

3 x 3200 = P2 x 250

Divide both side by 250

P2 = 3 x 3200/250

P2 = 38.4 atm

Therefore, the pressure of the gas if ethylene is supplied by a 250.0 L tank is 38.4 atm
