Calculate the mass of calcium carbide produced if 1770 kJ of heat is absorbed.
Flauer [41]

Answer:

m=243.72g

Explanation:

Hello,

For the given chemical reaction:

CaO(s) + 3 C(s) \rightarrow CaC_2(s) + CO(g)

Whose heat of reaction is 464.8 kJ/mol which means that energy is absorbed due to the chemical reaction, we can compute the moles of calcium carbide via the following relationship:

n=\frac{1770kJ}{464.8 kJ/mol}\\ \\n=3.81mol

Then, since the molar mass of calcium carbide is 64 g/mol, the yielded mass turns out:

m=3.81mol*\frac{64g}{1mol}\\ \\m=243.72g

Best regards.

KonstantinChe [14]

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.
