Answer:
2.95 * 10^23 atoms
Explanation:
The number of atoms in a mole is always equal to <u>Avogadro's constant</u>, which is <u>6.02214076×10²³ mol⁻¹</u>.
To find the number of atoms in 0.490 moles of barium, multiply it with <u>Avogadro's constant</u>:
0.490 mol * 6.02214076×10²³ mol⁻¹ ≈ 2.9508 * 10^23
Convert to SigFigs (if necessary):
2.95 * 10^23
Answer:
Refractive index applies to gases, liquids and some solids, but if a solid seems totally opaque then refractive index might not be an obvious property. Similarly viscosity is not obviously applicable to most solids.

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE
<h3>
What is the book value?</h3>
- Book value is the worth of an asset based on its balance sheet account balance in accounting.
- The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses.
- Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities.
- In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both.
- The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked.
- When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."
Therefore, the statement "the book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine" is TRUE.

Answer:
The correct answer is skeleton equation.
Explanation:
In chemistry, the skeletal formula of a compound is an abbreviated representation of its molecular structure. Skeleton formulas are used because they clearly show complicated structures, they are fast and simple to draw.
All atoms that are not carbon or hydrogen are represented by their chemical symbol. The relative amounts of reagents and products are not indicated.
Have a nice day!
