It was the meaning of "tiny" in Greek then... atomus
Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.
It would be CH2! you’re just simplifying C4H8, 4 can go into C4 1 time (so we just say C) and 4 can go into H8 2 times (H2)
Answer:
B Fluorine is the most reactive because it has 7 electrons in the outer shell.
Explanation:
The valid conclusion about the reactivity of the elements is that fluorine is the most reactive because it has 7 electrons in the outer shell.
- Reactivity of elements is in a bid to attain a stable configuration of their atoms.
- Fluorine belongs to group 7 on the periodic table.
- To complete its octet, it requires just one electron.
- This makes it very reactive
- On getting an electron, it becomes like the nearest noble gas, Neon.
