Predict the formula for a compound made from X and Y2–.

1 answer:

7 0

A compound is composed of a cation that is considered as the positively charged ion and an anion that is considered on the other hand as the negatively charged ion. In this case, when a compound is formed, an exchange of numbers reflected on the subscript takes place. The compound formed thus is X2Y

Zepler [3.9K]

Answer:

$\boxed{8.4\times 10^{-10} \text{ N}}$

Explanation:

The formula for the force exerted between two ions is

$F = \dfrac{kq_{1}q_{2}}{r^{2}} = \dfrac{kz_{1}z_{2}e^{2}}{r^{2}}$

where the Coulomb constant

k = 8.988 × 10⁹ N·m·C⁻²

Data:

z₁ = +2; r₁ = 0.62 nm

z₂ = -1; r₂ = 0.121 nm

Calculations:

r = r₁ + r₂ = 0.62 + 0.121 = 0.741 nm

$F =\dfrac{8.988 \times 10^{9} \text{ N $\cdot$ m$^{2} \cdot$ C$^{-2}$} \times 2 \times (-1) \times ( 1.602 \times 10^{-19} \text{ C})^{2}}{(0.741 \times 10^{-9} \text{ m})^{2}}\\\\ = -\mathbf{8.4\times 10^{-10}} \textbf{ N}\\\text{The attractive force between the ions is } \boxed{\mathbf{8.4\times 10^{-10}} \textbf{ N}}$

What functional group would be expected to be found in the major, and final, organic product upon completion of the reaction bet

taurus [48]

Answer:

Ketone

Explanation:

The reaction between 1-hexyne and mercuric sulphate in the presences of aqueous sulphuric acid is a reaction that leads to the formation of a product containing a carbonyl group(a ketone in this case).

This reaction occurs in alkynes but the product formed depends on the structure of the alkyne; an aldehyde or ketone may be formed depending on the structure of the alkyne.
