The hcl(g) molecule has a bond length of 127 pm and a dipole moment of 1.08
Roman55 [17]

Let us assume that this molecule is 100 percent ionic. In that case, the charges are distinguished by a bond length.

h = Q × r

= (160 × 10⁻¹⁹ c) (127 × 10⁻¹² m) (10 / 3.336 × 10⁻³⁰ cm)

= 6.09 D.

The actual dipole moment is = 1.08 D

Therefore, the percent ionic character is,

= 1.08 D / 6.09 D × 100

= 17.7 %.

The radioisotope that has the longest half-life is the best to use in powering planet and space exploration vehicles because the
Diano4ka-milaya [45]

Answer:

U-238

Explanation:

For a given radioisotope, half life can be defined as the time taken for the isotope to decay into one-half of its original amount. Mathematically, this is expressed as:

t_{1/2} = \frac{0.693}{k}

where k = rate constant for the radioactive decay process

Greater the t1/2 longer will be its stability.

Based on the given data, U-238 has the largest half life and therefore will be best suited for applications mentioned.
