How much heat is required to change 100.0g of ice at 0 ∘C into water at 0 ∘C? use heat curve formulas, tell me if there is more info you need.

Please help, I am v confused :)

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

What is the value of keq for the reaction expressed in scientific notation?
