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
Answer: hydrolysis oxidation acidification
Explanation:
they break down, dissolve, or create new elements
The component of the dri reflects the requirement of a nutrient for 50 percent of healthy americans and canadians in a specific life stage and gender is Estimated Average Requirement (EAR).
What is EAR?
A daily food intake number known as the Estimated Average Requirement (EAR) is one that is thought to satisfy the needs of 50% of healthy persons in a given life stage and gender group.
Based on a review of the scientific literature, the estimated average requirements (EAR) are predicted to meet the needs of 50% of the population in that age range.
It serves as the foundation for the creation of RDAs and is employed to assess the sufficiency of nutritional consumption for a given population.

Answer:
Explanation:
Hello,
In this case, by using the Avogadro's law which allows us to understand the volume-moles behavior as a directly proportional relationship:
We can compute the volume of 34.3 g of argon by representing it in mole as shown below:
Thus, we find:
Best regards.
