How many atoms are in 1.7 mols of CHF3
erastovalidia [21]

Given :

Number of moles of CHF₃ is 1.7 .

Solution :

We know, 1 mole of any complex contains 6.022 × 10²³ molecules.

Let, 1.7 moles of CHF₃ contains n numbers of molecules.

So, n = 1.7 × 6.022 × 10²³ molecules

n = 10.2374 × 10²³ molecules

n = 1.0237 × 10²³ molecules

Hence, this is the required solution.

Complete the chemical equation for the formation reaction of ethyl alcohol (C2H5OH,l) from its constituent elements in their sta
oee [108]

Answer:

2C(s, graphite)+ 3H₂(g) + ½O₂(g) ⟶ C₂H₅OH(ℓ)  

Explanation:

The thermodynamic standard state of elements and compounds is defined as their most stable state at 25 °C and 1 bar

The elements in ethanol, C₂H₅OH, are C, H, and O.

Their most stable states at standard conditions are C₂H₅OH(ℓ), C(s, graphite), H₂(g), and O₂(g)

The equation for the formation of ethanol from its elements is  then

2C(s, graphite) + 3H₂(g) + ½O₂(g) ⟶ C₂H₅OH(ℓ)
