Answer:

D

Explanation:

Compounds 1 and 3 are lonic.Because ionic compounds are composed of oppositely charged ions that are attracted to one another,

they require more energy to melt than covalent bonds. just usign he process of elimination you get rid of A and B becuase covalant compound contaIN same negatively charged particles that contain requrie less energy to melt and since two and four have low melting point its d

Given the balanced equation representing a reaction:Cl2==> Cl + Cl
andrew11 [14]
The correct answer is option 1. The balanced reaction represents that a bond is broken and energy is absorbed. Cl2 are held by covalent bonds that are strong. Therefore, energy is required to break these bonds. The energy supplied is absorbed for the reaction to proceed.

The total volume in milliliters of a glucose-water solution is given by the equation below: V = 1001.93 + 111.5282m + 0.64698m^2
vagabundo [1.1K]

Answer:

a. Vₐ = 111.5282 + 1.29396m

b. For m = 0.100m; Vₐ = 111.6576

Explanation:

The partial molar volume of compound A in a mixture of A and B is defined as :

V_a = \frac{dV}{dn_a}

Where V is volume and n are moles of a.

a. As molality is proportional to moles of substance, partial molar volume of glucose can be defined as:

Vₐ =  dV / dm =  d(1001.93 + 111.5282m + 0.64698m²) / dm

<em>Vₐ = 111.5282 + 1.29396m</em>

b. Replacing for m = 0.100m:

Vₐ = 111.5282 + 1.29396×0.100

<em>Vₐ = 111.6576</em>

<em></em>

Unknown element x is a metal that ionically bonds to sulfur.is the formula, x3s feasible? why or why not?a)it is feasible. the t
nasty-shy [4]
The correct answer is:
d) No, it is not feasible. three metallic ions cannot provide the exact number of electrons that one sulfur needs for the ionic bond.
Because Sulfur is divalent so it need to gain 2 electrons from metal so if we have 3 metals they can't provide only two electrons only.
