To see if an equation is balanced, make sure that each side of the reaction has an equal number of the types of atoms. The one that has a mismatch is A
Animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
The one you have selected is correct. CO is a compound because it contains more than one element.
the nebular theory states that the solar systems developing <u><em>rotations </em></u>revolve around sun. it is located in the milky-way. revolving around the <u><em>sun</em></u>, with <u><em>gravity</em></u> pulling it, an interstellar cloud of dust and gas, is formed. (i.e. the nebula that we are speaking)
this formation is a<u><em> protostar</em></u>. the idea in the theory states that the <u><em>nebula</em></u> has flattened into a <u><em>disk</em></u> called the "protoplanetary disk"; and over time, the debreis eventually formed this disk. (i.e. creating the milky-way)
hopefully this helped, thank you!! :D
You’ll need to be sure to count all the atoms in each side of the chemical equation.
