Answer:
4
Step-by-step explanation:
The reactions are:
Glycolysis: 1 glucose ⟶ 2 pyruvate
Link reaction: 2 × [1 pyruvate ⟶ 1 acetyl CoA]
Citric acid cycle: 2 × [1 AcetylCoA ⟶ 2 CO₂]
Now, add the reactions, cancelling species that occur on both sides of the reaction arrow,
1 glucose ⟶ <u>2 pyruvate
</u>
<u>2 pyruvate</u> ⟶ <u>2 acetyl CoA
</u>
<u>2 AcetylCoA </u>⟶ 4 CO₂
<em>Overall</em> : 1 glucose ⟶ 4 CO₂
For each mole of glucose, four molecules of CO₂ are released in the citric acid cycle.
Answer:
PCl₃
Explanation:
To determine the empirical formula of a compound, we need to follow a series of steps.
Step 1: Divide each percent composition by the atomic mass of the element
P: 22.6/30.97 = 0.729
Cl: 77.4/35.45 = 2.18
Step 2: Divide all the numbers by the smallest one, i.e. 0.729
P: 0.729/0.729 = 1
Cl: 2.18/0.729 ≈ 3
The empirical formula of the compound is PCl₃.
The reaction is based on law of conservation of mass.
The balanced chemical equation is
<h3>What is law of conservation of mass?</h3>
Every balanced chemical equation follows the direction of conservation of mass. This law states that mass can neither be completed nor can be destroyed but it can only be transformed from one condition to another form. This law likewise states that the total number of individual atoms on the reactant side must be comparable to the total number of individual atoms on the product side.
- The Law of Conservation of Mass holds because naturally occurring elements are stable under the conditions located on the surface of the Earth. Most elements come from fusion reactions found only in stars or supernovae.
- Consequently, in the ordinary world of Earth, from the peak of the highest mountain to the depths of the deepest ocean, atoms are not transformed into other elements during chemical reactions. Because of this, individual atoms that make up living and nonliving subjects are very old and each atom have a history.
- An individual atom of a biologically essential element, such as carbon, may have expended 65 million years buried as coal before standing burned in a control plant, followed by two decades in Earth's environment before being disbanded in the ocean,

The Clausius-Clapeyron equation:
ln(P₁/P₂) = ΔH/R * (1/T₂ - 1/T₁)
-25 °C = 248 K and pressure is 344 torr
-6.4 °C = 266.6 K and pressure is 760 torr (atmospheric)
Using the equation:
ln(760/344) = ΔH/62.364 * (1/248 - 1/266.6)
ΔH = 175.7 kJ/mol
Moles of H₂ are needed to produce 9.33 moles of NH₃ : 13.995
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
The reaction coefficient in a chemical equation shows the mole ratio of the reactants and products
Reaction for the synthesis of ammonia :
N₂+3H₂⇒2NH₃
moles of NH₃ = 9.33
From equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol H₂ :
