Hey there!
C₆H₁₄ + O₂ → CO₂ + H₂O
Balance H.
14 on the right, 2 on the left. Add a coefficient of 7 in front of H₂O.
C₆H₁₄ + O₂ → CO₂ + 7H₂O
Balance C.
6 on the left, 1 on the right. Add a coefficient of 6 in front of CO₂.
C₆H₁₄ + O₂ → 6CO₂ + 7H₂O
Balance O.
2 on the left, 12 on the right. Add a coefficient of 6 in front of O₂.
C₆H₁₄ + 6O₂ → 6CO₂ + 7H₂O
Our final balanced equation: C₆H₁₄ + 6O₂ → 6CO₂ + 7H₂O
Hope this helps!
According to the all-or-none principle, the thing that would happen if a cell were depolarized twice the amount needed to produce an action potential would be : Nothing would happen because the cell must be polarized to fire.
all-or-none principle stated that the strength by which muscle fiber respond to a stimulus is independent to the strength of the stimulus.
Answer:
There will be weight, there will be volume, there will be height
Explanation:
Answer:
The reaction of one mole of oxygen (O2) releases 445 kJ of energy.
Explanation:
Firstly, the reaction is exothermic since the sign of enthalpy change ΔH is negative.
The balanced equation: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l): ΔH = −890 kJ,
Shows that 1 mole of CH₄ react with 2 moles of oxygen and releases 890 kJ.
So, every choice says that absorb is wrong (choice 1& 3).
Choice no. 4 is wrong since it says that 2 moles of methane releases 890 kJ, because only one mole release this amount of energy.
So, the right choice is The reaction of one mole of oxygen (O2) releases 445 kJ of energy.
