Answer:four hydrogen atoms
Explanation:
Answer:
Explanation:
Hello,
In this case, considering the given chemical reaction, we can use the molar mass of octane (114.23 g/mol) and the 2:16 molar ratio with carbon dioxide to compute the emitted moles of CO2 to the atmosphere via the following stoichiometric procedure:
Which also corresponds to the following mass:
Best regards.
In a controlled experiment the factor tested is called the experimental group
Answer is: D. Neon is the most stable element because its highest occupied energy level is filled.
Neon (symbol: Ne) is an element (noble gas) with atomic number 10, which means it has 10 protons and 10 electrons.
Electron configuration of neon atom: ₁₀Ne 1s²2s²2p⁶.
Noble gases are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
