The overall charge of an ionic compound is ______________. a. always positive b. usually positive c. usually negative d. usually

telo118 [61]

Answer:

d. usually neutral

Explanation:

The overall charge of an ionic compound is usually neutral.

There is no net charge on the compound formed by an ionic bond due to the electrical stability that is derived from this bond association.

In an ionic bond, a metal transfers some of its electrons to a non-metal. The metal is electropositive and the non-metal is electronegative.

Therefore, the result is that two ions are produced which attracts each other with an electrostatic force.

A large piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is subme

Lerok [7]

The density of the substance is 10.5 g/cm³.

The jewelry is made out of Silver.

Density ρ is defined as the ratio of mass m of the substance to its volume V. The cylinder contains a volume V₁ of water and when the jewelry is immersed in it, the total volume of water and the jewelry is found to be V₂.

The volume V of the jewelry is given by,

$V=V_2 -V_1$

Substitute 48.6 ml for V₁ and 61.2 ml for V₂.

$V=V_2 -V_1\\ =61.2 ml -48.6 ml\\ =12.6 ml$

calculate the density ρ of the jewelry using the expression,

$\rho =\frac{m}{V}$

Substitute 132.6 g for m and 12.6 ml for V.

$\rho =\frac{m}{V}\\ =\frac{132.6 g}{12.6 ml} \\ =10.5 g/ml$

Since $1 ml=1 cm^3$ ,

The density of the jewelry is 10.5 g/cm³.

From standard tables, it can be seen that the substance used to make the jewelry is silver, which has a density 10.5 g/cm³.
