Answer:
The answer is
<h2>324 K</h2>
Explanation:
To express a given temperature in degree Celsius to Kelvin simplify add 273 to the given value
That's
<h3>K = 273 + °C</h3>
where
K = Kelvin
°C = value in degree Celsius
From the question the value to be converted is 51°C
It's equivalent in Kelvin is
K = 273 + 51
We the final answer as
<h2>324 K</h2>
Hope this helps you
Answer:
S-type or silaceous asteroids are made up primarily of stony materials and nickel-iron. They inhabit the inner Asteroid Belt. M-type, or metallic, are made up mostly of nickel-iron, and are found in the middle region of the Asteroid Belt

Answer:
Explanation:
Tarnish
ing
Tarnishing is a chemical property.
One substance changes into another substance with different properties. For example, the tarnish on silverware is formed by the reaction of silver with hydrogen sulfite to form black silver sulfide.
2Ag + H₂S ⟶ Ag₂S + H₂
Freezing
Freezing is a physical property, because the composition of the substance does not change. After liquid water has frozen to ice, it is still water, but in the solid state.
H₂O(ℓ) ⇌ H₂O(s)
Rusting
Rusting is a chemical property, because a new substance with different properties is formed.
A simple equation for the formation of rust is
2 Fe + 3O₂ + H₂O ⟶ Fe₂O₃·H₂O
