Bubbling if you put it in a liquid
Answer:
1. Alkali metals (group 1)
2. halogens (Group 17)
3. noble gasses (group 18)
Explanation:
1. alkali metals only have one valence electron meaning that they really want to lose that one valence electron to get a full octet.
2. halogens have 7 valence electrons meaning that they just need to gain 1 to get a full octet.
3. Nobel gasses already have a full octet meaning that they don't want to react. (atoms only react to get a full octet)
I hope this helps. Let me know if anything is unclear.
The overall process of cellular respiration is to use the energy or ATP in the sugars in your body, to supply your cells with with oxygen and water.
Alfred Wegener
Explanation:
Alfred Wegener in 1912, proposed the theory of continental drift from his careful studies of different land masses. From his observations, he suggested the following:
- Some fossils of tropical plants were found in polar and temperate regions.
- Fossils of mesosaurus were found in South America and South Africa now separated by the Atlantic ocean.
- He fitted the continents into a giant land mass puzzles.
- Coal beds in Europe were similar to those in United States.
- Mountain chains in the edge of West Africa was similar to that of Eastern part of South America.
His theory lacked a mechanism which facilitated the plate movement.

Answer:
See explanation
Explanation:
I know that we usually associate the sp3 hybridization to the tetrahedral shape. This is common in molecules such as CH4. So it may sound somewhat strange that NH3 molecule has an sp3 hybridized nitrogen atom and a trigonal pyramidal geometry.
Let us recall that the central nitrogen atom in NH3 has a lone pair of electrons. These lone pairs causes more repulsion than bond pairs. As a result of the presence of this lone pair, the bond angle in the NH3 molecule is distorted away from the expected 109.7 degrees in tetrahedral geometry and the bonding groups are now arranged in a trigonal pyramidal geometry(with bond angle less than 109.7 degrees) to minimize electron pair repulsions.
