State the color of methyl orange in a sample of NaOH

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
