In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.

<h3>What is a formula unit?</h3>

A formula unit is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations.

  • Step 1: Convert 40.32 kg to g.

We will use the conversion factor 1 kg = 1000 g.

40.32 kg × (1000 g/1 kg) = 4.032 × 10⁴ g

  • Step 2: Convert 4.032 × 10⁴ g to moles.

We will use the molar mass of NaHCO₃ as the conversion factor.

4.032 × 10⁴ g × (1 mol/84.01 g) = 479.9 mol

  • Step 3: Convert 479.9 moles to formula units (fu).

We will use Avogadro's number as the conversion factor.

479.9 mol × (6.022 × 10²³ fu/1 mol) = 2.890 × 10²⁶ fu

In 40.32 kg of NaHCO₃, there are 2.890 × 10²⁶ formula units of NaHCO₃.

Why do we have to balance chemical equations
Lunna [17]

Answer:

  • <em>Chemical equations are balanced </em><u>to comply with the law of conservation of mass.</u>

Explanation:

Law of conservation of mass states that matter cannot be either created or destroyed.

A skeleton chemical equation shows the reactants and products of a chemical reaction without taking into account the real proportion in which the reactants combine and the products are obtained.

An example of a skeleton reaction is the combustion of methane:

  •    CH₄ + O₂ → CO₂ + H₂O

Such as that equation is shown, there are four atoms of hydrogen in the reactants but only 2 atoms of hydrogen in the products. Also, there are 2 atoms of oxygen in the reactants but three atoms of oxygen in the products. This seems to show that some atoms of hydrogen have been destroyed and some atoms of oxygen have been created. This is impossible as it is against the law of conservation of matter.

Then, to show a real situation, the chemical equation of combustion must be balanced, adjusting the coefficients. This is the balanced chemical equation:

  •    CH₄ + 2O₂ → CO₂ + 2H₂O

Now you see that the number of atoms of each matter is conserved: the number of carbon atoms in each side is 1, the number of atoms of hydrogen in each side is 4, and the number of atoms of oxygen in each side is 4. Thus, by balancing the chemical equation, the law of conservation of mass is not violated.

For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation
Y_Kistochka [10]

Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation energy for this reaction is described below.

Explanation:

When the rates are equal and the concentration of reactants and products are constant not equal. Other like activation energies and potential energies are not necessary for equilibrium.

The activation energies of the forward and reverse reactions ,the rates of the forward and reverse reactions are  25 minutes ago.

For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45
