1. Preparation of Sodium carbonate. Sodium carbonate is an important industrial raw material widely used in industries such as glass, textiles, fertilizers, and soaps. There are many methods for preparing Sodium carbonate, and one of them is the Solvay process. The molecular weight of Sodium carb...
A solution's concentration expressed in moles of solute per liter of solution. What does the measure molarity mean? By mass, the water is the solute and the sucrose is the solvent. Consider the following: There are- 3.3 x 10^24 molecules in 100 g of water- 3.5 x 10^23 molecules in ...
Earthworms are probably one of the most effective natural composters. They work silently below, churning and enriching the earth. To see how many earthworms you have in your yard, you can take your own 12-inch by 12-inch sample and count the number of earthworms. If you’re worn out ...
In Equation (1), 𝑚𝑖mi refers to the masses and 𝑀𝑖Mi the molar masses of the mixture components. For the studied MEA/EG/ChCl system [52], this composition showed an optimal combination of absorbing capacity (𝑚CO2mCO2, moles of CO2 absorbed by 1 kg of a solution) and ...
