Ionic bonding involves ionic bonds forming between a metal and a non- metal (show where metals and non- metals lie on the periodic table) and electrons are transferred. The structure of this ionic compoun...

Empirical formula is the simplest whole number ratio of atoms of each element in a compound. With the empirical formula and relative molecular mass, we can determine the actual molecular formula of a comp...

The Earth's atmospheric oxygen increased because plants and algae developed and used carbon dioxide for photosynthesis. This led to a decrease in atmospheric carbon dioxide levels. The origins of the ocea...

Magnesium oxide has a giant 3D lattice structure formed by strong electrostatic forces of attraction between the positively charged magnesium ions and the negatively charged oxygen ions. These ionic bonds...

NO2 is a strongly electron withdrawing group, making the ring more electrophilic (pi withdrawing).NMe2 is a strongly electron donating group, making the ring more nucleophilic (pi donating).These changes ...
