How many grams of hydrogen gas would be produced from the use of 9.5 miles of aluminum?

Answer:

28.5g of H2

Explanation:

First, let us write a balanced equation for the reaction. This is illustrated below:

2Al + 6HCl —> 2AlCl3 + 3H2

From the balanced equation,

2moles of Al produced 3moles of H2.

Therefore, 9.5 moles of Al will produce = (9.5x3)/2 = 14.25moles of H2.

Now let us convert 14.25moles of H2 to grams as illustrated below:

Molar Mass of H2 = 2x1 = 2g/mol

Number of mole H2 = 14.25moles

Mass of H2 =?

Number of mole = Mass /Molar Mass

Mass = number of mole x molar Mass

Mass of H2 = 14.25 x 2

Mass of H2 = 28.5g

If you start with 3 moles of sodium and 3 moles of chlorine to produce sodium chloride, what is the limiting reagent?(you will n
Harman [31]

Sodium(Na) is the limiting reagent.

<h3>What is Limiting reagent?</h3>

The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. The precise quantity of reactant required to react with another element may be estimated from the reaction stoichiometry.

How do you identify a limiting reagent?

The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.

Start by writing the balanced chemical equation that describes this reaction

2Na_{(s)} + Cl_{2 (g)} -- > 2NaCl_{(s)}

Notice that the reaction consumes 2 moles of sodium metal for every 1 mole of chlorine gas that takes part in the reaction and produces 2 moles of sodium chloride.

now we can see that we have 3 moles of sodium and 3 moles of chlorine, according to question. so, we can say that sodium is the limiting reagent in the given situation.

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that mac
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.

I NEED ANSWER PLEEEAASSEE!!!
emmasim [6.3K]
The answer is B. This is because Sodium has 1 valence electron and Fluorine has 7 valence electrons. All elements want 8 valence electrons so they may be stale, like the noble gases are. Hope this helps.

Mars2501 [29]

Answer:

Measuring the Volume of Solids

Rectangular prism - Multiply the measurement of the length times the width, then times the height.

Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
