<h3>The molecular formula of this protein : C₁₈H₄₂O₁₂N₆</h3><h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
The principle of determining empirical formula and molecular formula
- Determine the mass ratio of the constituent elements of the compound.
- Determine the mole ratio by dividing the elemental mass with the relative atomic mass obtained by the empirical formula
- Determine molecular formulas by looking for values of n
Find mol ratio for every component :
N (r=14 g/mol) :
Mass of Nitrogen :
40.4-(17.16+3.17+13.71)=6.36 g
C : H : O : N = 1.43 : 3.17 : 0.857 : 0.454 = 3.15 : 7 : 1.89 : 1=3:7:2:1
Empirical formula : C₃H₇O₂N
Molecular mass of protein :
(C₃H₇O₂N)n=565.75
(12.3+1.7+2.16+14)n=565.75
(89)n=565.75
n=6.4≈6
so the molecular formula : C₁₈H₄₂O₁₂N₆
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Explanation:
In the combustion reaction methane (CH₄) will react with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).
CH₄ + O₂ → CO₂ + H₂O
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
So the balanced chemical reaction will be:
CH₄ + 2 O₂ → CO₂ + 2 H₂O

Answer:
Hi
The high dipole moment of water and its ease in forming hydrogen bonds make it an excellent analysis. A molecule is soluble in water if it can interact with its molecules through hydrogen bonds or ion-dipole interactions.
With anions that have oxygen they can form hydrogen bonds, since oxygen acts as their acceptor. The attraction of the anion on the water dipole must be taken into account. The same goes for Cl-F, which have solitary electron pairs and can act as hydrogen bridge acceptors. On the other hand, cations such as Na+, K+, Ca++ or Mg++ are surrounded by water molecules to which they are joined by dipole ion interactions while oxygen atoms are oriented towards the catión.

Answer: sulphur is an element with RAm of 32g/mol
Saturated solution is the solution which do not dissolve more soulute at given temperature
<u>A solution of NaF is added to a solution that is 0.0144 M in Ba²⁺. When the concentration of F- exceeds </u><u>0.011 m, BaF₂</u><u> will precipitate.</u>
Let's consider the solution of BaF₂.
BaF₂(s) ⇄ Ba²⁺(aq) + 2 F⁻(aq)
We can use the solubility product constant (Ksp) to find the equilibrium concentration of F⁻ when [Ba²⁺] is 0.0144 M.
When [F⁻] exceeds 0.011 M, BaF₂ will precipitate.
A solution of NaF is added to a solution that is 0.0144 M in Ba²⁺. When the concentration of F- exceeds 0.011 M, BaF₂ will precipitate.
What is BaF₂.?
- BaF2 crystallizes in the cubic Fm3m space group and has a fluorite structural makeup.
- Eight comparable F1 atoms and Ba2+ are joined in a cubic shape with the body in the middle. The average Ba-F bond length is 2.72.
- Four comparable Ba2+ atoms are joined with F1 to create a mixture of corner- and edge-sharing FBa4 tetrahedra.
