Calculate the number of moles of CO required to react with 2.99 g of Fe2O3. Do not include units in your answer. Round to the tenths place or further.

Its trait is different and it the organism survive

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.

"electrical energy" transforms to "thermal energy".hope my answer has you : )
