The missing element : ₇¹⁴N
<h3>Further explanation</h3>
Given
Reaction
₆¹⁴C ⇒X + ₋₁⁰e
Required
The missing element
Solution
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles ₀γ⁰
- positron particles ₁e⁰
- neutron ₀n¹
In a decay reaction, the sum of the mass number and atomic number before and after the decay is the same.
The element X :
Atomic number = 6 + 1 =7
Mass number = 14 + 0 = 14

A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Find number of moles and divide by volume to get molarity
The reaction that releases energy as heat is called an Exothermic reaction. This reaction does obey the law of conservation by preserving the energy present in the molecule and converting it to thermal heat to maintain it's from. Most reactions obey the law of conservation of energy.
