<h3>What is
Fluorine?</h3>
The chemical element fluorine has an atomic number of 9 and the symbol F. The lightest halogen, it is an extremely poisonous, pale yellow diatomic gas under normal conditions. It is exceedingly reactive and, as the most electronegative element, reacts with all other elements with the exception of argon, neon, and helium.
Fluorine is the 24th most abundant element overall and the 13th most abundant on Earth. In order to decrease the melting temperatures of metal ores for smelting, fluorite, the main mineral source of fluorine, was added. The Latin verb fluo, which means "flow," gave the mineral its name. Fluorite was first described in 1529.

<span>If the the level of water in a container is compared before and after the fusion, it can be realized that the ice has a higher level than that of liquid water: solid and liquid water does not have the same volume.
</span><span>We can generalize:
A state change always causes a change in volume.
Comment:
Water is an exception, volume increases during a melting for most of substances.</span>
Answer:
P = 8000 Kg m/s
When speed is increased to 50 m/s,
P = 40,000 kg. m/s
Explanation:
Given data:
Mass = 800 Kg
Velocity = 10 m/s
Momentum = ?
Speed increased = 50 m/s
Momentum = ?
Solution:
Formula:
P = mv
P = 800 kg× 10 m/s
P = 8000 Kg m/s
When speed is increased to 50 m/s.
P = mv
P = 800 kg× 50 m/s
P = 40,000 kg. m/s
Answer:

Explanation:
deals wit pain help with healing
M₁ x V₁ = M₂ x V₂
2.5 x V₁ = 0.50 x 100.0
2.5 x V₁= 50
V₁ = 50 / 2.5
V₁= 20 mL
