States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

For the denitrification [microbiological conversion of nitrite/nitrate (N-containing contaminants) to nitrogen gas (harmless end product)] to be more effective, an external carbon source (e.g., methanol) is frequently added for denitrifiers (denitrifying microorganisms) during the reaction. The following chemical reaction is for when methanol is added for this purpose. Calculate how much (concentration) of methanol (in mg/L) needs to be added to completely convert 30 mg/L of NO3--N to N2 gas. 0.1667 CH3OH + 0.1343 NO3- + 0.1343 H+ ↔ 0.0143 C5H7O2N + 0.06 N2 + 0.3505 H2O + 0.0952 CO2
Suppose that you plan to make 10 grams of MgCO₃ by reacting MgSO4 with Na₂CO₃ [Figure 10]. However, Na₂CO₃ is unavailable and you need to replace it with K₂CO₃. Which statement is correct? * a) It can be predicted form the periodic table that the yield of MgCO₃ will be more when using K₂CO₃ because potassium is more reactive than sodium. b) It can be predicted form the periodic table that the precipitate of MgCO₃ will form faster because potassium is more reactive than sodium. c) None of these statements is correct. d) Both these statements are correct.
