Burrows, tracks, coprolites, nests and footprints are examples of traces that can be found in a fossil.
There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
Hope this helped
Have a nice day :)
The correct response would be A. The slowest step that determines the speed(rate) of the overall reaction.
Carbon disulfide is prepared by heating sulfur and charcoal. the chemical equation is S2(g) + C(s) <---> CS2 (g) Kc = 9.40 at 900 K.
Hope this helps:)
Answer:
<u>Physical Properties</u>
Alkali metals are good conductors of heat and electricity while halogens are poor conductors of heat and electricity.
Only specific to Alkali metals: They are soft and can be cut by knife.
<u>Chemical</u><u> </u><u>Properties</u>
Alkali metals have 1 valence electron while halogens have 7 valence electrons.
Alkali metals react with non-metals to form ionic compounds while halogens react with non-metals to form covalent compounds.
You can also look at the trends ( melting/boiling point, reactivity) down their group.
