According to Avogadro’s hypothesis, the volume (V) of a gas is directly proportional to the number of moles (n) . V ∝ n Where V : Volume n : Number of moles The above proportionality can be written as follows: V = kn Where k : proportionality constant This equation can be represented as a graph. Consider a gas with n1 moles with a volume V1. Suppos...
Below are some examples of Avogadro’s law in everyday life . 1. Respiration: When we respire, we breathe in oxygen. The more we breathe, the more our lungs will expand. 2. Deflation: When the air is released from an inflated tire, the number of moles decreases. The shape of the tire also changes since its volume decreases. 3. Inflation: When a wate...
Explains Gay-Lussac’s lawDetermines the atomicity of the gasesDetermines the molecular formula of a gaseous compoundGives the relationship between gram molecular mass and gram molecular volume of gasProblem 1: Two moles of helium gas fill up an empty balloon to a volume of 2.5 L. What would be the volume of the balloon if an additional 1.5 moles of helium gas is added at constant temperature and pressure. Solution: Given n1= 2 mol V1= 2.5 L n2= 2 mol + 1.5 mol = 3.5 mol From Avogadro’s law, V1/n1 = V2/n2 Therefore, the final volume of the ball...
- The reaction between gaseous sulfur dioxide and oxygen is a key step in the industrial synthesis of sulfuric acid: \( 2SO_{2}\left ( g \right ) + O_{2}\left ( g \right ) \rightleftharpoons 2SO_{3}\left ( g \right ) \)
- A 1.00 mol sample of NOCl was placed in a 2.00 L reactor and heated to 227°C until the system reached equilibrium. The contents of the reactor were then analyzed and found to contain 0.056 mol of Cl2.
- The water–gas shift reaction is important in several chemical processes, such as the production of H2 for fuel cells. This reaction can be written as follows
- In the water–gas shift reaction shown in Example 10, a sample containing 0.632 M CO2 and 0.570 M H2 is allowed to equilibrate at 700 K. At this temperature, K = 0.106.
- CO2 + H2O → C6H12O6 + O2. The first step to balancing chemical equations is to focus on elements that only appear once on each side of the equation. Here, both carbon and hydrogen fit this requirement.
- SiCl4 + H2O → H4SiO4 + HCl. The only element that occurs more than once on the same side of the equation here is hydrogen, so we can start with any other element.
- Al + HCl → AlCl3 + H2. This problem is a bit tricky, so be careful. Whenever a single atom is alone on either side of the equation, it is easiest to start with that element.
- Na2CO3 + HCl → NaCl + H2O + CO2. Hopefully, by this point, balancing equations is becoming easier and you are getting the hang of it. Looking at sodium, we see that it occurs twice on the left, but once on the right.
Dec 16, 2021 · The phase rule is an important generalization dealing with the behavior of the heterogeneous system. It is possible to predict qualitatively by means of a diagram the effect of changing pressure, temperature, and concentration at equilibrium.
Many chemical reactions are carried out in solutions, and solutions are also closely related to our everyday lives. The air we breathe, the liquids we drink, and the fluids in our body are all solutions. Furthermore, we are surrounded by solutions such as the air and waters (in rivers, lakes and oceans).
