(Originais Teachy 2023) - Question Hard of Chemistry

A pharmaceutical company is developing a new medicine. In one of the reactions, two reactants A and B are combined to form a product C. The reaction is represented as follows: A + B ⇌ C. Initially, the concentrations of A, B, and C were 5M, 4M, and 0M respectively. After reaching the equilibrium, the concentration of C was found to be 3M. Using the law of mass action, calculate the equilibrium constant for this reaction.
a.
1.5
b.
2.0
c.
1.0
d.
0.75
e.
2.5

In a chemical industry, the synthesis process of ammonia (NH3) occurs through the reaction between hydrogen (H2) and nitrogen (N2). This reaction is an example of a chemical equilibrium and is represented by the equation N2(g) + 3H2(g) ⇌ 2NH3(g). The initial quantities of the reactants are 2 mol of N2 and 10 mol of H2, and after reaching equilibrium, it was found that the concentration of NH3 is 1 mol/L. Considering that the volume of the reactor is 5L, solve the following items: 1. Determine the expression of the equilibrium constant (Kc) for this reaction. 2. Calculate the molar concentrations of the reactants and products at equilibrium. 3. Find the value of the equilibrium constant (Kc) and discuss the meaning of the obtained value in relation to the equilibrium of the reaction.

You are a scientist who is studying two different samples of matter: Sample A and Sample B. Sample A has a mass of 200 grams and a volume of 50 cm³. Sample B has a mass of 300 grams and a volume of 75 cm³. You want to compare their densities to determine which sample is more compact. To do this, you need to calculate the density of each sample using the formula: Density = Mass / Volume. After calculating, analyze which sample has the higher density and formulate a judgment about why this sample might be more compact than the other.
