Answer: (F) chemical energy
Explanation:
₈O¹⁸ + ₁¹H(proton) ⇒ ₉F¹⁸ + ₀n¹(neutron) + ₀γ⁰
(gamma)
<h3>Further explanation</h3>
Given
Fluorine-18
Oxygen-18
Required
Nuclear equation
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
The principle used is the sum of the atomic number and mass number before and after the decay reaction is the same
The reaction
₈O¹⁸ + ₁¹H(proton) ⇒ ₉F¹⁸ + ₀n¹(neutron) + ₀γ⁰
(gamma)
For metric unit conversions, figure out if you are going to go from a smaller measurement to a larger one, and vice versa. for small to large, divide by 10, 100, 1000 depending on how much different they are. ex 987 cm = 98.7 dm.
for large to small, multiply by 10,100, or 1000 depending. ex 987 km = 9870 hm.

Answer:
A condensation reaction joins two larger molecules by splitting out a smaller molecule — usually water or ammonia — between them.
In an esterification reaction, an OH from the acid and an H from the alcohol form a molecule of water.
The larger parts join to form the ester.
Ethanol and butanoic acid react to form ethyl butanoate.
