This is a combination reaction, where a hydrocarbon reacts in the presence of oxygen to produce carbon dioxide and water.
Answer:
Molecular formula is C21H40
Explanation:
Use the formula CnH2n-2
That is the alkyne formula
Answer:
False
Explanation:
The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.
This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).
An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.
Answer: self-actualization (C)
Explanation:
it’s at the top of the hierarchy of needs.
Answer:
0.267 mol
Explanation:
The <em>unbalanced equation</em> for the reaction that takes place is:
Once we balance it we're left with:
- 2C₈H₁₈ + 25O₂ → 18H₂O + 16CO₂
Using the <em>stoichiometric ratio </em>of water and octane from the balanced reaction, we can <u>convert mol of water into mol of octane</u>:
- 2.40 mol H₂O *
= 0.267 mol C₈H₁₈
Thus 0.267 moles of octane are needed to produce 2.40 mol of water.
