Metallic tantalum crystallizes in a body-centered cubic lattice, with one Ta atom per lattice point. If the edge length of the u

nit cell is found to be 328 pm, what is the metallic radius of Ta in pm
Chemistry

Answer:

The radius of the atom Ta is 142pm

Explanation:

To solve this question we need to know that for a body-centered cubic lattice we have the equations:

X = 4/√3 R

<em>Where X is edge length and R is radius of the atom in the lattice.</em>

<em />

If adge length of unit cell is 328 pm:

328pm = 4/√3 R

328pm * √3 / 4 = R

142pm = R

The radius of the atom Ta is 142pm

Olive oil has a density of 0.92g/ml. How much would 1.0 Liter of olive oil weigh in grams?
Julli [10]

Answer:

9.2x10²g

Explanation:

Data obtained from the question include the following:

Density = 0.92g/ml

Volume = 1L = 1 x 1000 = 1000mL

Mass =..?

Density is simply defined as the mass of the substance per unit volume of the substance. Mathematically it can be represented as:

Density = Mass /volume.

Mass = Density x volume

Mass = 0.92 x 1000

Mass = 9.2x10²g.

Therefore, 1L of olive will weigh 9.2x10²g.

What is the mass of silver bromide that precipitates when 2.96 g of iron(iii) bromide is combined with excess silver nitrate?
KIM [24]

<u>5.6400 </u>is the mass of silver bromide that precipitates when 2.96 g of iron(iii) bromide is combined with excess silver nitrate.

<h3>Difference between silver bromide and iron(iii) bromide</h3>

  • Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials. AgBr is widely used in photographic films and is believed by some to have been used for making the Shroud of Turin. The salt can be found naturally as the mineral bromargyrite.

  • Iron(III) bromide is the chemical compound with the formula FeBr3. Also known as ferric bromide, this red-brown odourless compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds. It dissolves in water to give acidic solutions.

A gas absorbs 10J of heat and is simulataneously comptessed by a constant external pressure of 0.5atm from 4L to2L in volume.Wha
Ne4ueva [31]

Answer:

B. 111 J

Explanation:

The change in internal energy is the sum of the heat absorbed and the work done on the system:

ΔU = Q + W

At constant pressure, work is:

W = P ΔV

Given:

P = 0.5 atm = 50662.5 Pa

ΔV = 4 L − 2L = 2 L = 0.002 m³

Plugging in:

W = (50662.5 Pa) (0.002 m³)

W = 101.325 J

Therefore:

ΔU = 10 J + 101.325 J

ΔU = 111.325 J

Rounded to three significant figures, the change in internal energy is 111 J.
