Which ion does not have a Roman numeral as part of its name? a) {Fe}^{2+} b) {Pb}^{2+} c) {Sn}^{2+} d) {Zn}^{2+} b) a) d)

Answers

Answer 1

The ion that does not have a Roman numeral as part of its name is {Zn}^{2+}.

Explanation: Zinc ion has no roman numeral.

Zinc(II) or Zn2+ is a cation having a charge of +2, indicating that it has lost two electrons.

It is also one of the most common trace elements in the human body and is required for numerous metabolic activities. It is located in cells throughout the body, particularly in the liver, pancreas, and bone.

It is the most important metal in the brain and is required for proper growth and development. In the name of other cations, Roman numerals are used to indicate their charge.

For example, Iron(II) is {Fe}^{2+}, Iron(III) is {Fe}^{3+}, Lead(II) is {Pb}^{2+}, and Tin(II) is {Sn}^{2+}.

Among all the options, {Zn}^{2+} is the ion that does not have a Roman numeral as part of its name.

The density of titanium is 4.51g/cm^3. What is the volume (in
cubic inches) of 3.5lb of Titanium? this could be helpful D=M/V

Answers

The volume of 3.5 lb of titanium is 21.47 in³.

The density of titanium is 4.51 g/cm³.The weight of titanium is 3.5 lb.

Formula used:

Density, D = M/V, where D is density, M is mass, and V is volume.

The conversion factor of 1 inch³ = 16.39 cm³.1 lb = 453.592 g.

First, we will calculate the mass of titanium.

3.5 lb = 3.5 × 453.592 g

= 1587.772 g

Next, we will calculate the volume of titanium.

Volume of titanium = Mass of titanium / Density of titanium

= 1587.772 g / 4.51 g/cm³

= 352.044 cm³

Next, we will convert the volume from cm³ to in³.

1 inch³ = 16.39 cm³.

Volume of titanium in in³ = Volume of titanium / 16.39

= 352.044 cm³ / 16.39

= 21.47 in³
