A Group 2 metal with an electron configuration of [Ne]3s2 combines with fluorine (F2) to
lidiya [134]

The molar mass of the product is equal to 62g/mol.

<h3>Mole calculation</h3>

To calculate the molar mass of a compound it is necessary to have knowledge of the atomic mass of all the elements involved.

In the case of the question, we have the reaction between flourine and magnesium, which represents the element of group 2 with the presented electronic configuration.

Thus, we have the following reaction:

                                   Mg^{+2} + 2F^{-1} = MgF_2

So, just add the molar masses, having:

MM_Mg = 24.3g/mol\\MM_F = 19g/mol

                                               24.3 + 19 + 19 = 62.3g

So, the molar mass of the product, round to the nearest tenth, is equal to 62g/mol.

Which of the following statements characterizes nuclear fission?
san4es73 [151]

Answer: C) the splitting of a nucleus released a large burst of energy

Explanation:

nuclear fission occurs when an isotope (usually unstable) is hit with particles such as neutrons and splits, resulting in an extreme burst of energy.

for instance, the atomic bombs developed by the U.S. during WWII were products of nuclear fission in which plutonium-239 and uranium-235 were struck by a neutron that hit either nucleus of either isotope. The result was the neclus split into fragments that released huge amounts of energy snd the fission process became self-sustaining as neutrons produced by the splitting nucleus hit other nuclei and produce more fission, causing a chain reaction.
