Question

? + 40₁₈Ar → 43₁₉K + ₁₁H How do I solve this?

A. Balance the chemical equation.
B. Identify the reactants and products.
C. Determine the atomic numbers of the elements involved.
D. Calculate the molar mass of each compound.

Answer 1

The missing reactant to balance the nuclear reaction ?+40₁₈Ar → 43₁₉K + 1₁H is a Neutron (n) with a mass number of 1 and an atomic number of 0.

Step-by-step explanation:

To balance the nuclear reaction ?+40₁₈Ar → 43₁₉K + ₁₁H, we need to identify the missing reactant, which is deduced from the conservation of mass and charge. The atomic number (bottom number) on the left must add up to the atomic number on the right, as must the mass number (top number). The missing reactant must supply 3 units of mass and 1 unit of charge since Argon (Ar) has a mass number of 40 and an atomic number of 18, while Potassium (K) has a mass number of 43 and an atomic number of 19, and Hydrogen (H) has a mass number of 1 and an atomic number of 1.

The missing reactant is Neutron (n) with a mass number of 1 and an atomic number of 0. The balanced nuclear equation is 1n+40₁₈Ar → 43₁₉K + ₁₁H.
