Consider the reaction at 298 K. 2H2(g)+O2(g)⟶2H2O(g) Δ°=−483.6 kJ/mol

Calculate the quantities for ΔSsys, ΔSsurr, ΔSuniv in J/(mol K)

How much energy moves onto the next level, in an energy pyramid

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
