Answer:
53.85%
Explanation:
Data obtained from the question include:
Mass of antimony (Sb) = 27.6g
Mass of Fluorine (F) = 32.2g
Mass of compound = 59.8g
Percentage composition of fluorine (F) =..?
The percentage composition of fluorine can be obtained as follow:
Percentage composition of fluorine = mass of fluorine/mass of compound x 100
Percentage composition of fluorine = 32.2/59.8 x 100
= 53.85%
Therefore, the percentage composition of fluorine in the compound is 53.85%
The greenhouse effect increases the temperature of the Earth by trapping
heat in our atmosphere. This keeps the temperature of the Earth higher
than it would be if direct heating by the Sun was the only source of
warming.
When the sunlight reaches the surface of the Earth, some of it is absorbed
which warms the ground and some bounces back to space as heat. Greenhouse gases that are in the atmosphere absorb and then redirect some of this heat back towards the Earth.
When a nuclide's nucleus contains more protons than neutrons, a positron is created, whereas radionuclides are utilized to emit both a positron and a neutrino.

What exactly does positron emission tomography entail?</h3>
In the field of medical diagnostics, it is simple to monitor the positron emission of radiotracers. Positron-emission tomography, also known as PET scans, is frequently used to examine the structure and function of the brain. When an isotope annihilates an electron, positrons are released, which are used in positron-emission tomography. As a result, alpha photons are released that are 180 degrees apart from one another. The devices can now identify these protons, and they can also evaluate photos. A positron emission tomography (PET) scan is an imaging procedure that can help show how your tissues and organs' metabolisms or biochemical processes work. In order to display both typical and abnormal metabolic activity, the PET scan uses a radioactive substance (tracer).
