By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
You can find carbon by itself or with other naturally occurring compounds, in all organic compounds (carbohydrates and nucleic acids), and in every living thing
Answer:
a)decrease
b)increase
c)smaller
d)smaller
Explanation:
Ionization energy decreases down the group due to increase in the atomic radius. The distance between the outermost electron and the nucleus increases hence the nuclear attraction for the outermost electrons become smaller and the ionization energy also become smaller as electrons are now easily removed from the outermost shell.
Hence the group of answer choices provided above.
Endothermic is when the compound absorbs energy in the reaction. Exothermic is the opposite: the compound releases energy in the reaction.
