Chemistry
1 answer:
vovikov84 [41]3 years ago
4 0

Answer:

0.71

Explanation:

The molecular mass of NaCl is, 23+35.5

= 58.5

1 mole means molecular mass (in gram)

In 58.5 gm NaCl there is 1 mole.

So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.

7. Suppose each of these isotopes emits a beta particle. Give the iso-
Volgvan

In a beta emission, the mass number of the daughter nucleus remains unchanged while the atomic number of the daughter nucleus increases by one unit. The following are isotopes produced when the following undergo beta emission;

1) potassium-42  ------> Ca - 42

2) iodine-131 ------------> Xe - 131

3)  iron-52 ---------------> Co - 52

4)  sodium-24 -----------> Mg -24

The daughter nucleus formed after beta emission is found one place after its parent in the periodic table.

Regarding the stability of the daughter nuclei, a nucleus is unstable if the neutron-proton ratio is less than 1 or greater than 1.5.

Hence, the following daughter nuclei are stable; Ca - 42, Xe - 131, Mg -24.
