Ignite curiosity with a biology tutor who enhances understanding through engaging visuals.

Sunitha and a student residing in High Point reviewed the properties and reactivity of metals, including transition metals, metallic bonding, and the extraction of iron from its ore. The student practiced identifying the reactivity of different metals based on observations and understanding the processes in a blast furnace. They discussed scheduling the next lesson and will continue with the remaining material then.

During their recent chemistry lesson, Sunitha and Ifadha thoroughly reviewed periodic table trends, covering electronic configuration, core charge, electronegativity, atomic radius, ionization energy, metallic character, and reactivity. They also explored the properties and uses of various metals. Their lesson concluded with a plan to continue with Chapter 3 on Saturday, focusing on the chemical properties of metals.

Sunitha provided comprehensive chemistry instruction to a student from Modesto Junior College. They reviewed atomic structure, isotopes, and emission spectra, covering electron arrangement and ionization energy. The student learned a method for writing electronic configurations using SPDF notation and how it relates to the periodic table. Sunitha assigned practice problems up to element 21 and will cover the D block in the next lesson.

During their chemistry lesson, Sunitha and Ifadha delved into stoichiometry, limiting reagents, and analytical techniques such as colorimetry and UV-visible spectroscopy. Ifadha honed her skills by practicing calculations and identifying concentrations using calibration curves. They also discussed atomic emission and absorption spectroscopy and their applications, and plan to review the chapter further in their upcoming lesson.

Sunitha and a student reviewed redox reactions and delved into quantitative analysis, focusing on gravimetric analysis and stoichiometry. The student, who attends the University of Illinois Chicago, practiced calculating mole ratios and determining the mass of salts in solutions using precipitation reactions. They also discussed limiting and excess reactants, and Sunitha assigned practice problems on gravimetric analysis for the next lesson.

Sunitha and Ifadha had a comprehensive chemistry lesson, where they explored chemical contaminants and salts found in water. They thoroughly discussed their sources, potential health effects, and various methods for sampling and analysis. Specific topics included heavy metals, the process of bioaccumulation, the characteristics of hard water, and techniques for salinity testing. Their next lesson is planned to focus on the analytical techniques used to quantify these substances, incorporating calculations based on mole concepts.
