Answer:
The balanced equation is.
CH₄ + 2O₂ → CO₂ + 2H₂O
Explanation:
CH₄ + O₂ --> CO₂ + H₂O
You have 4 H in reactant side. In order to balance the H, you add 2 in water, in product side.
Now, you unbalanced the O, because you have 2 O from CO₂ and 2 O from water. As you have 4 O in total, you add a 2 in the O₂ in the reactant side. C is balanced because you have 1 C on each side
Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.
Answer:
i think O.C is correct answer

Bromocresol Green belongs to a class of dyes called as <span>Sulfonephthaleins. This dye imparts different colours at different pH's.
Colors at different pH:
</span> Bromocresol Green has a transition pH range between 3.8 and 5.4.
Color Below pH 3.8:
Bromocresol Green imparts Yellow color below pH 3.8.
Color Above pH 5.4:
Bromocresol Green imparts Blue color above pH 5.4.
Due to different colors at different pH this compound is used at Indicator in quantitative analysis techniques like Titration.
Result:
Bromocresol Green will give Blue color at pH 7.
