What is the difference between melting point and boiling point?​

Chemistry

MrRissso [65]2 years ago

The melting point is the temperature a substance must reach to go into its liquid phase (or solid) and a boiling point is the temperature a substance must reach to go into its gas phase (or liquid). For example, water must be 0ºC to melt or freeze and 100ºC to boil.

The melting point is a certain temperature a thing has to be at to melt or to turn into a liquid and the boiling point is the same thing its just with gas

How does the structure of compounds determine the properties of the compounds?
aleksley [76]

Answer:

All of these properties are due to the chemical structure of the compound. The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.

Explanation:

Hope it helps.

Calculate the mass of atoms of carbon and 3 molecules of hydrogen​
PSYCHO15rus [73]

The mass of atoms of carbon and 3 molecules of hydrogen​ : 18 g/mol

<h3>Further explanation </h3>

An atomic mass unit ( amu or "u") is a relative atomic mass of 1/12 the mass of an atom of carbon-12.  

The molar mass(molecular mass-formula mass-molecular weight(MW)) of a compound is the sum of the relative atomic mass (Ar) of the constituent elements of the compound

Can be formulated :  

M AxBy = (x.Ar A + y. Ar B)  

The mass of atom of Carbon(C)⇒Ar = 12 g/mol

The mass of 1 molecule of Hydrogen - H₂(MW) : 2 g/mol

The mass of 3 molecules of Hydrogen : 3 x 2 = 6 g/mol

So the mass of atoms of carbon and 3 molecules of hydrogen​ :

\tt 12+6=18~g/mol

Consider the reaction.
N76 [4]

Answer: m = 50 g ZnSO4

Explanation: First is convert the moles of Zn to the moles of ZnSO4 by having their mole ratio which is 2:2 based from the balanced equation. Next is convert the moles of ZnSO4 to mass using its molar mass.

0.311 mole Zn x 2 moles ZnSO4 / 2 moles Zn

= 0.311 moles ZnSO4

0.311 moles ZnSO4 x 161 g ZnSO4 / 1 mole ZnSO4

= 50 ZnSO4
