A lead sphere has a mass of 1.20 x 104 g, and its volume is 1.05 x 103 cm^3. Calculate the density of lead.

Hatshy [7]

Answer: The density of lead will be $11.42g/cm^3$

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of lead= $1.20\times 10^4g$

Volume of lead = $1.05\times 10^3cm^3$

Putting in the values we get:

$Density=\frac{1.20\times 10^4}{1.05\times 10^3}=11.42g/cm^3$

Thus density of lead will be $11.42g/cm^3$

What is an ionic bond? A. the attraction positive ions have for free electrons B. the force that holds the valence electrons to

Olin [163]

Ionic bond is a type of chemical bond that refers to the bonding of <span>oppositely charged ions (anions and cations) because of attraction and the </span>transfer of valence electron(s) between atoms. Cation is the metal that loses electrons and become a positively charged cation, and anions are the nonmetal that accepts those electrons to become a negatively charged anion.
According this explanation, an ionic bond is:
B. the force that holds the valence electrons to the atom

The formula ca(no3)2 tells us that one formula unit of this compound is composed of ________ calcium atoms, ________ nitrogen at

ad-work [718]

Answer:- The formula $Ca(NO_3)_2$ tells us that one formula unit of this compound is composed of one calcium atom, two nitrogen atoms, and six oxygen atoms.

Explanations:- Subscripts tell us about the number of atoms of the element for which they are used. For example, here the subscript of Ca is one, it means there is one calcium atom in the given one formula unit.

When we have subscripts inside and outside the parenthesis then they are multiplied and the outside subscript is considered for all the atoms present inside the parenthesis.

Here, for the given chemical formula, the subscript of N is 1 and the subscript present outside is 2. So, 1 x 2 = 2 and for oxygen, 3 x 2 = 6

So, we have one calcium atom, two nitrogen atoms and six oxygen atoms for one formula unit of given compound.
