CO cause polyatomic means many types of atom.
S8 only contain one type of atom - S
Na only contain one type of atom - Na
Cl2 only contain one type of atom - Cl
CO contains two types of atoms - C and O
Answer:
ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃
Explanation:
- Assume that the solution is formed via dissolving solute A in the molecules of Solvent B.
<em>The formation of the solution goes through 3 steps:</em>
1- The dissociation of the solute A particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₁ > 0 beause this is an endothermic process.
2- The dissociation of the solvent B particles, solute breaks apart the intermolecular forces holding the molecules together. It has ΔH₂ > 0 because this is an endothermic process.
3- The particles of the solvent and solute are holding together. It has ΔH₃ < 0 because this is an exothermic process.
- The enthalpy of the solution (ΔH of solution) will be equal to the sum of the enthalpy change of the three steps.
- ΔH of solution = ΔH₁ + ΔH₂ + ΔH₃.
Conduction as it transmits energy from solid to solid through a medium
Answer:
The scaling factor is 5.
Explanation:
Hello there!
In this case, since the scaling factor is defined as the ratio of the molar mass of the molecular formula (complete) to the empirical formula (simplified), it is possible to compute it for the empirical formula of CH2O whose molar mass is 30 g/mol (12+2+16) as shown below:
Therefore, we can also infer that the molecular formula would be:
Best regards!
The formula shows the number of each type of atom in the molecule. There are 2 atoms of sodium, one atom of chromium and four atoms of oxygen, being a total number of 7 atoms.
