The half-life in years of Neptunium-237 which was the first isotope is 2.1 10^{6} years.

Neptunium is most stable and Neptunium-237 is undergoes alpha decay, it means Neptunium-237 is decays by the emission of alpha particles . Seven alpha particles is emitted during decay of  Neptunium-237.  Neptunium-237 is radioactive actinide  elements and first  transuranium element.

The transuranium synthesis process involves creating a transuranium element through the transmutation process . The transmutation process  is the process of creating heavy elements from light elements. Hence the process is the transmutation of light elements. There are two types: artificial and natural transmutation.

An agent of weathering where liquid water seeps into the cracks of rocks is called?​
babunello [35]

Answer:

Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze. ... This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing.

A gas occupies 210 mL at -73°C to have the same gas occupy 360 mL:
const2013 [10]

Answer:

a. The temperature should be increased.

b. 342.86K

Explanation:

Using Charles law equation as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question, the following information were given:

V1 = 210mL

V2 = 360mL

T1 = -73°C (-73 + 273 = 200K)

T2 = ?

Using V1/T1 = V2/T2

210/200 = 360/T2

Cross multiply

200 × 360 = 210 × T2

72000 = 210T2

T2 = 72000/210

T2 (new temperature) = 342.86K

A mixture of 0.600 mol bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C. Br2(g) + I2(g) 2 IBr(g
Tamiku [17]

Answer:

The answer to your question is   Ke = 1.4751

Explanation:

Data

bromine = 0.6 mol

iodine = 1.6 mol

volume = 1 L

Ke = ?

Iodine monobromide concentration = 1.190 M

Process

1.- Write the balanced chemical equation

                    Br₂  +    I₂   ⇒   2IBr

2.- Write the formula for Ke

     Ke = [IBr]²/[Br₂][I₂]

3.- Substitution

      Ke = [1.19]² / [0.6][1.6]

4.- Simplification

      Ke = 1.4161 / 0.96

5.- Result

      Ke = 1.4751
