Answer:
5.42x10^24 atoms/1 x 1 mole/6.022x10^23
= 9.5 mol
1: viewing any chemical reaction in a laboratory
2: dangerous to look at when it burns & used in photography, fireworks, and flares
3: the product
The keg for the reaction
2 SO2(g) + O2(g) → 2 SO3(g) is
Keg = [SO3]^2/ {(SO2)^2 ( O2)}
Keg (equilibrium constant) is the ratio of of equilibrium concentration of the product raised to the power of their stoichiometric coefficient to the equilibrium concentration of the reactant raised to the power of their stoichiometric coefficient.
Chemical ; Conducts heat and electricity, Reacts with dilute acids.
Physical : Ductile and Malleable.
