Answer:
1) Dispersion forces: It is a type of force which is present between atoms and molecules. It is a weakest intermolecular force that occurs between atoms. It is also called induced dipole-induced dipole attraction.
2. Dipole-dipole: It is a type of attractive force which is present between the negative end of one molecule with the positive end of another molecule. This type of attractive force occurs between polar molecules.
3) Hydrogen bond: It is a type of electromagnetic force which is present between hydrogen and high electronegative atoms such as nitrogen and oxygen etc.
<span>Chemical transformation: it's all transformation changes the composition of matter, i.e. that matter produces a new substance with different initial properties burning sugar to make caramel, we cannot retrieve the initial sugar.

Answer:
An alloy is a combination of metals or metals combined with one or more other elements. For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver. Elemental iron, combined with non-
Explanation:
that's what an alloy is all the rocks including gold silver combined with copper and sterling silver
I'm pretty sure it's A, but then again I'm only in 8th grade. Sorry if this doesn't help:(
Answer:
Molecular formula = C₅H₁₀
Explanation:
From the question given above, the following data were obtained:
Empirical formula of compound => CH₂
Molar mass of compound = 70.1 amu
Molecular formula of compound =...?
The molecular formula of a compound is usually a multiple (n) of the empirical formula i.e
Molecular formula = [CH₂]ₙ
Thus, to obtain the molecular formula of the compound, we must first determine the value of n. The value of n can be obtained as follow:
[CH₂]ₙ = 70.1
[12 + (2×1)]n = 70.1
[12 + 2]n = 70.1
14n = 70.1
Divide both side by 14
n = 70.1 / 14
n = 5
Molecular formula = [CH₂]ₙ
Molecular formula = [CH₂]₅
Molecular formula = C₅H₁₀
Thus, the Molecular formula of the compound is C₅H₁₀.
