Why were there so many heated debates around the development of the cell theory? There were no concrete information about the development of the cell, thus they did not have the evidence to come to conclusions. People would argue about what theory was correct. who named the cell?
Answer:
Solid= all together in lines
Gas= floating round everywhere
Liquids = a lot more than gas but not all together like solid
Answer:
hexane
Explanation:
This is a 6- carbon hydrocarbon with no multiple bonds or any functional groups (such as -OH). Thus, the prefix 'hex' refers to the 6 carbons and 'ane' refers to the molecule being an alkane.
Naming molecules:
<u>Number of </u><u>carbons</u>
• pentane: 5 carbons
• hexane: 6 carbons
• heptane: 7 carbons
• octane: 8 carbons
• nonane: 9 carbons
<u>Functional </u><u>groups</u> (for 6- carbons molecules)
• Alkene (C=C): hexene
• Alcohol (-OH): hexanol
• Alkyne (C≡C): hexyne
Well one mole of stuff, any stuff, including carbon dioxide, specifies

Answer:
in an oxygen atom there are:
protons:8
electrons:8
neutrons:8
Explanation:
this is because the atomic number of oxygen is 8 and that is the proton number and the electron number is the same as the atomic number
