Two reactions of MG and HCL happen. One at 20°C and one at 60°C. Which reacts faster and why?

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

Describe the interaction that occurs between two objects with the same electrical charge.
