The atomic masses in the Periodic Table are not integral numbers. For example, carbon is listed as 12.011 amu instead of 12.000 amu. Why?

Does the amount of heat absorbed as 1 kg of saturated liquid water boils at 100°C have to be equal to the amount of heat released as 1 kg of saturated water vapor condenses at 100°C?

es the molecule defective leading to sickle cell anemia. Predict whether the following hypothetical change would or would not have a major effect at position 6.

At the beginning of this lesson, there was a question about two acids. Vinegar, which contains acetic acid, is used in foods and has few safety concerns. Hydrochloric acid is used in chemistry labs and requires the use of safety goggles and gloves.

In an analysis of interhalogen reactivity, 0.440 mol of ICl was placed in a 5.00-L flask, where it decomposed at a high T: 2 ICl (g) ⇌ I2 (g) + Cl2 (g) Calculate the equilibrium concentrations of I2, Cl2, and ICl (Kc = 0.110 at this temperature).
