The heat is measured with degree Celsius and degree Fahrenheit. The heat capacity depends on both it's mass and it's chemical composition.
Answer:
Explanation:
Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.
Answer:
2.71×10²⁴ particles
Explanation:
Applying Avogadro's constant
Avogadro's constant states that, The number of specified particles contained in a mole of a substance is equal to 6.02×10²³.
From the question,
If one mole of chlorine contains a particle of 6.02×10²³,
Therefore,
4.5 moles of chlorine will contain a particle of (4.5× 6.02×10²³)
⇒ 27.09×10²³
Hence the number of particle contained in 4.5 moles of chlorine ≈ 2.71×10²⁴ particles
An insect would have a harder time walking on ethanol than it would water. Water has stronger intermolecular forces which leads to higher surface tension. The higher surface tension allows for the insect to be easily supported
