What coefficient well O2 have after balancing this equation
C4H8 + O2 -> CO2 + H2O
A. 4
B. 8
C. 6
D. 2.5
Answers
The coefficient for O₂ after balancing the equation is 4. The correct answer is A. 4.
To balance the equation C₄H₈ + O₂ → 4CO₂ + 4H₂O, we need to ensure that the number of each type of atom is the same on both sides of the equation.
Starting with carbon (C), we have 4 carbon atoms on the left side and only 1 on the right side (in CO₂). To balance carbon, we place a coefficient of 4 in front of CO₂:
C₄H₈ + O₂ → 4CO₂ + H₂O
Next, we move on to hydrogen (H). There are 8 hydrogen atoms on the left side, but only 2 on the right side (in H₂O). To balance hydrogen, we place a coefficient of 4 in front of H₂O:
C₄H₈ + O₂ → 4CO₂ + 4H₂O
Now, let's consider oxygen (O). On the left side, we have O₂, which contains 2 oxygen atoms. On the right side, there are 4 CO₂ molecules, each containing 2 oxygen atoms, and 4 H₂O molecules, each containing 1 oxygen atom. So, the total number of oxygen atoms on the right side is (4 x 2) + (4 x 1) = 8.
To balance oxygen, we need to have 8 oxygen atoms on the left side as well. Therefore, we place a coefficient of 4 in front of O₂:
C₄H₈ + 4O₂ → 4CO₂ + 4H₂O
Therefore, the coefficient for O₂ after balancing the equation is 4.
The correct answer is A. 4.

Answers
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
