A balance chemical equation is an equation describing a chemical reaction with the right number of molecules to cancel out each side of the equation.
For example:
H2 + O2 —> H2O
Make sure the number of molecules in your reactants equal the number of molecules in your product
2H2 + O2 —> 2H2O
(4 hydrogens and 2 oxygens = 4 hydrogens and 2 oxygens)
Answer:
Gravitational force
Explanation:
Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.
In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.
Answer:
Low pressure spins counterclockwise, causing weather systems to move from west to east in the Northern Hemisphere.
This is due to lower air pressure further North America than in the tropics. Since low-pressure systems spin counterclockwise, winds move from the west to the east.
Prevailing weather results from expansive convection currents formed by the temperature differences on the surface of the earth as latitude increases. The Coriolis effect adds the twist.
I got this from a few sites so use this information as you want and be careful <3
Fossil evidence because these changed occur over long time periods (millions of years).
